Cmd+K search did not find what you wanted fast enough. It listed subagent threads, ranked matches inside words too high, did not favor what you used recently, and mixed late message hits in with title hits, so rows jumped.

How

One score: match quality × use. One shared scorer (packages/shared/src/paletteSearch.ts, no new dependency) rates each word: a whole word beats a word prefix, which beats words typed together ("vscode"), a one-letter typo, and a match inside a word. Thread scores then multiply by how recently you wrote in and opened the thread, capped so use never beats a better match. Subagent threads are gone everywhere.
Use and pick memory on the server. Opening a thread sends the existing thread.visit command with opened: true, plus the query when you picked it from search. The thread keeps a decayed open count and its last 3 picked queries (opens, about 100 bytes), so this syncs across devices. For three weeks, typing a query you picked before puts that thread first among word matches. Older servers ignore the new fields.
Two sections. "Threads" ranks locally on every keystroke. "In messages" comes from the server and always sits below, so late results never move the rows above. When an environment answers late, rows already shown hold their places, and the keyboard highlight stays on its row. "Searching messages…" shows in the footer, so the palette does not change height. Rows say why they matched ("Branch: …", "PR: #…"), and a row that cannot say why is left out.
FTS5 for messages. Migration 069 adds a contentless trigram index (case and Latin accents ignored) with a backfill, kept in sync by triggers that skip streaming deltas. Search reads the newest matches once and grades them with the same word rules as titles: words side by side rank first, then words near each other, then words apart. The snippet starts where the words meet. SQLite builds without trigram support fall back to the old scan.
Message results open at the message. On web, picking a message row (in Cmd+K or the sidebar) opens the thread with find on the word at that message. On mobile, it loads history down to that message and scrolls there.
Every surface. Web and desktop share the palette and sidebar. Mobile uses the same ranking in its palette, thread list, archive, and composer mentions. The MCP t3_thread_search tool ranks titles the same way. Palette rows are keyed by environment.

Proof

Ranking: 54 realistic queries from a copy of real data (584 threads, 15.8k messages), each with an expected first result. Top 1: main 41/54, #24032 48/54, this PR 53/54 (MRR 0.80 → 0.99). On the same set, uFuzzy gets 36, fzf 40, and cmdk's command-score 40. They ignore word boundaries or recency, so this PR adds no matcher dependency.
Message search, through the real service: 3-27 ms on that data, 19-88 ms on a copy with 20× the messages. Reads stop at the newest 10,000 index hits, so time stays flat as history grows. Index: 21 MB for 7.6 MB of text. Backfill: 1.4 s for 15.8k messages, once.
Snippets: for 25 two-word queries, 133 of the top 213 message rows show every word in the visible line.
Keystroke cost: 0.5-1.9 ms to rank 584 threads.
Mobile: verified on an Android 15 emulator. "nvme ssd" in the thread list opens "XFS Second Drive Worktrees" at its 2nd of 72 user messages; a thread matched by its title still opens at the newest message. iOS is covered by unit tests and typecheck only.
Review: three independent model reviewers reviewed 16 rounds. The last round scored 9, 9, and 8.5; the findings from that round are fixed here. A simplification pass in the middle cut the scorer from 1,435 to about 1,100 lines; later fixes brought it to about 1,250.
Tests: focused tests for the scorer, palette grouping, message ranking and stable order, the FTS migration, index sync and rebuild, the query plan, the bounded read, picks on the server, and the mobile jump and list helpers.

Overlaps

Builds on #24032 (merged), which hid subagent threads and ranked whole words first.
#16858 (search qualifiers) changes the same search query, palette filtering, and mobile palette. It conflicts and will need a rebase onto this.
#22099 (environment-scoped palette rows) is included here, so that PR becomes redundant.
#21444 touches CommandPalette.tsx and conflicts in small ways. #23156 merges cleanly.

Follow-ups

Find opens at the word's first occurrence in the matched message. A phrase whose spacing the snippet collapses (a code block, or words across paragraphs) opens find with no results.
"cant" does not find "Can't", "vscoed" does not find "VS Code", and two-letter words do not search messages alone.
Hex text in titles and branches counts as words ("cafe" in "7cafe52bb8"). Messages already guard this.
Threads that match only by project are left out of "In messages" even past the 20 thread rows. Two filters keep title matches out of message rows; one would do.
When one thread matches a typo exactly, the typo pass does not run, so the correct spelling can be missing.
Composer @-mentions can match by branch or PR title without showing why.
The row PR badge still uses the old substring matcher. useThreadSearch and the palette assembly are near-identical on web and mobile.

Fixed in 2825166b62. When the plain phrase test fails and either the query or the message has non-ASCII text, messageMatcher now runs the phrase on the accent-folded text too. "Le Café open late" for cafe open and "The cafe open late" for café open both score 1.25 (new cases in paletteSearch.test.ts).

A query like rust a drops messages containing rust à, so adding the short token a makes accent-insensitive message search miss valid results. The SQL prefilter uses SQLite’s ASCII-only lower() and literal instr() matching before messageMatcher can fold accents; normalize this prefilter the same way or leave the short-token check to the matcher.

Not changing this. The short-token prefilter is a substring check, so a message passes when the letters appear anywhere in it. rust à is only dropped when the message has no plain a at all. The filter runs in SQL before the 2,000-hit limit on purpose: if messageMatcher did that check after the read, a common word plus a rare short word would use up the bounded read on hits that then get dropped.

Not changing this here. It is a known limit of the fold. Queries are normalized to NFC, and message text from keyboards and agents arrives composed. Matching decomposed text would mean dropping the combining marks, which changes string length. Snippet highlights and in-thread find depend on offsets into the original text, so this needs an offset map, not a change to foldInPlace.

searchThreads can return no message matches even when eligible message-only threads exist: messageHitsQuery limits results to 2,000 before excludedThreadIds discards title-matching threads here. Apply the exclusion in the SQL query before its hit limit so those threads cannot crowd out the reserved message results.

Fixed in 2825166b62. Listed threads are now removed in the eligible CTE (excludedThreadIds on the search request), so they leave before the hit limit, and the JS skip is gone. New test: "leaves titled threads out before the hit limit" (a titled thread with 2,000 newer hits). It fails on the previous head and passes now.

Walkthrough

This change adds shared search ranking, indexed server-side message search, thread-open ranking data, and updated web and mobile search flows. Search results can include message matches. Selecting a message match can navigate to that message.

Changes: Thread and message search

Layer / File(s)	Summary
Shared search ranking and contracts `packages/shared/src/paletteSearch.ts`, `packages/shared/src/threadPullRequests.ts`, `packages/contracts/src/orchestrationV2.ts`, `packages/contracts/src/threadSearch.ts`	Shared utilities add query folding, ranking, message matching, highlighting, and thread-open scoring. Contracts add open statistics and message-match fields.
Indexed server search `apps/server/src/orchestration-v2/ThreadSearch.ts`, `apps/server/src/orchestration-v2/messageSearchIndex.ts`, `apps/server/src/persistence/Migrations/069_ThreadMessageSearch.ts`, `apps/server/src/mcp/toolkits/thread/`, `apps/server/src/persistence/`, `apps/server/scripts/migrate-dev-db.ts`	The server indexes eligible messages, ranks title and message matches, and applies project scoping. Migration, maintenance, development database copying, and MCP search use the search service.
Thread-open ranking state `packages/client-runtime/src/state/threadSearch.ts`, `packages/client-runtime/src/operations/commands.ts`, `apps/server/src/orchestration-v2/Orchestrator.ts`, `apps/web/src/components/chat/ThreadVisitWatermark.tsx`, `apps/mobile/src/features/threads/ThreadDetailScreen.tsx`	Client and server code record thread opens and picked queries. Thread shells carry open statistics, and client search subjects use local and server open data.
Web palette and sidebar search `apps/web/src/components/CommandPalette`, `apps/web/src/components/Sidebar`, `apps/web/src/components/chat/threadFindActionBus.ts`, `apps/web/src/components/chat/useThreadFind.ts`, `apps/web/src/state/queries.ts`, `apps/web/src/components/settings/settingsSearch.ts`, `docs/user/thread-sidebar.md`	The web palette and sidebar rank thread and message matches, display match context, and open find at a message match. Search state retains eligible prior results while a new query loads.
Mobile palette and thread-list search `apps/mobile/src/features/keyboard/`, `apps/mobile/src/features/threads/threadListV2`, `apps/mobile/src/features/threads/ThreadNavigationSidebar.tsx`, `apps/mobile/src/features/home/HomeScreen.tsx`, `packages/client-runtime/src/composerThreadItems.ts`	Mobile thread lists and palettes use shared ranking, distinguish message-only results, and request message navigation when such a result is selected. Composer thread suggestions use the shared scorer.
Mobile message-jump navigation `apps/mobile/src/features/threads/ThreadFeed.tsx`, `apps/mobile/src/features/threads/ThreadRouteScreen.tsx`, `apps/mobile/src/features/threads/threadMessageJump.ts`, `apps/mobile/src/lib/threadActivity.ts`	Mobile jump requests are thread-scoped and expire after 30 seconds. The thread screen loads history through the target, expands folded runs when needed, and scrolls to the message when it is available.

Full details: Title check

Explanation

The title "feat(search): Cmd+K finds the right thread first, with indexed message search" matches the main changes in the raw summary. The changeset ranks thread search with a shared scorer (paletteSearch.ts), adds server-side open and pick tracking, and adds an FTS5 trigram index for message search (migration 069). The title follows conventional commit format and is specific. It is slightly long at 77 characters and combines two themes, but both are real parts of the change.

Full details: Description check

Explanation

The description follows the repository template's main sections: Problem, How, Proof, and Overlaps/Follow-ups. It explains the problem, the approach, and the verification with concrete metrics. The template asks for a Scope and approval section that links a triaged bug issue or maintainer-approved discussion. The description has an Overlaps section but no approval link or statement of why the change qualifies without one. The Verification section gives measured results and states the iOS gap. The template's comment block is absent, so the section heading names differ from the template (Problem, Change, Scope and approval, Verification).

Resolution

Add a "Scope and approval" section that links the triaged issue or maintainer-approved discussion for this scope. This PR is large (about 4,000+ added lines across server, web, mobile, and shared packages) and builds on #24032, so it needs explicit approval. If no prior approval exists, explain why it qualifies, which the template does not allow for changes of this size. Rename the sections to match the template headings (Problem, Change, Scope and approval, Verification) or confirm that the current headings are acceptable. Also state the agent model and harness at the end of Verification. The description already names Claude Opus 5.5 and Claude Code, so this part is met.

Apply excludedThreadIds in SQL, before MESSAGE_HIT_LIMIT cuts the hits.

searchMessages drops excluded threads in JS, after messageHitsQuery has already applied LIMIT ${MESSAGE_HIT_LIMIT}. searchThreads passes every title-matched thread as excludedThreadIds. A common query can match those threads in more than 2,000 newer messages. Those excluded rows then fill the hit window, and message-only threads never reach matchMessage. The MCP tool then returns no user/assistant rows, even though its description reserves a fifth of the limit for them. The comment on messageHitsQuery also says filters run before the limit, so hidden threads cannot crowd out a visible match. That rule does not hold for this filter.

Pass the excluded IDs as a TokenList and filter them in the eligible CTE.

🤖 Claude Opus 5.5 responding on behalf of Theo

Already fixed in 2825166b62, which landed after the commit this review read. excludedThreadIds is a TokenList on the search request and is filtered in the eligible CTE, before the hit limit. The JS skip is gone. The test "leaves titled threads out before the hit limit" covers a titled thread with 2,000 newer hits.

CcoderabbitaiBot11d ago

@t3dotgg Confirmed in the supplied ThreadSearch.ts: excludedThreadIds uses TokenList, the eligible CTE filters those IDs before MESSAGE_HIT_LIMIT, and the JavaScript skip is gone. This addresses the finding. No further change is needed for this thread.

Keep the open pending until visit support is known.

useThreadShell can replace the selected shell when a thread.updated event supplies a new shell. If lastVisitedAt changes from undefined to a supported value, this effect has already stored the thread key and claimed the open, so it returns without sending opened: true. Track the claimed open separately from the dispatched visit.

Note

🤖 Claude Opus 5.5 responding on behalf of Theo

Not changing this. lastVisitedAt is undefined only when the environment's server predates visits. Shells from that server do not gain the field later in the same session. The only way to hit this is a server upgrade while the thread stays open, and the cost is one open not counted toward ranking until the thread is opened again. Tracking a separate pending-open state for that would add more state than the case is worth.

CcoderabbitaiBot11d ago

@t3dotgg Understood. I treated lastVisitedAt === undefined as incomplete hydration rather than a server-version boundary. Given that contract, the extra pending-open state is not justified. I withdraw the finding.
