feat(search): full-text search in a publication's archive by peterkibuchi · Pull Request #205 · peterkibuchi/goldroad

peterkibuchi · 2026-10-14T21:18:16Z

Scope

Search on a publication's archive now covers the full text of every post, not
the titles and summaries of one loaded page. Results come ranked, with the
matching passage quoted and the matched words marked.

Index. Migration 0016_post_search.sql adds search_documents (the text
of each post) and post_search, an FTS5 index over it. The index is
external-content and kept in step by triggers. search_backfills tracks how
far each writer's backfill has got.
Writes. Publish, edit, scheduled publish, publish-now and delete update
the index after the record is live, and best-effort, so a D1 failure never
fails a publish. Account deletion removes the writer's index rows.
Backfill. /api/search/backfill indexes the signed-in writer's existing
posts, 20 per call. The dashboard calls it in the background until it says
done. Search answers from the index only after that, so it never quietly
misses older posts.
Reading. The archive's search box is a GET form (/@handle?q=…). It
works without JavaScript, and a search is a link you can share.

Other authors are not indexed at all. Their archives render here, but
indexing them means reading a whole repo because a stranger typed their handle
into a search box. We'd also have no signal when they edit or delete, and we'd
spend the free plan's 100,000 rows written a day on people who never signed up.
Their archives keep the old title-and-summary filter over the newest page, and
the page now says that's what it searched.

Risk

The nightly backup. D1 refuses to export any database that holds a virtual
table, so without a change the backup job would fail from the first night
after this migration. scripts/d1-export.sh exports the ordinary tables by
name. A table-scoped export also drops every index and trigger, so the script
appends those, the FTS5 table, and a rebuild of the index, each guarded with
IF NOT EXISTS. The workflow then loads the dump into a scratch SQLite
database and runs the index's integrity check before it encrypts anything. I
verified this against local D1 only, including a full restore into sqlite3. The
remote export with --table is untested. Please run the Backup workflow once
by hand after the migration lands, and before relying on it.

Migration 0016. It's additive: two tables, one virtual table, three
triggers. It's numbered 0016 because open PRs claim 0012 to 0015. Apply it
before the deploy that needs it. Whichever lands later needs its drizzle
snapshot re-chained (pnpm db:generate after rebasing).

An uncached query. A search can't use the edge cache. The cache key keeps
only cursor, so a cached search would serve the plain archive. And no purge
can reach a stored page per query after a delete or takedown. So each search
costs a DID lookup, one publication read from the writer's server, and two or
three D1 queries. Rows read stay in proportion to one writer's archive: the
writer is a token inside the FTS5 match, not a filter after the join. A flood
of distinct queries is the same lever ?cursor= already is, and the answer is
the same: a rate-limit rule at the CDN.

Known gaps. A change made in another app after the backfill isn't seen
until the post is next written here, for example a post deleted with a repo
tool. Every Goldroad path keeps the index current; a periodic re-walk would
close the rest, and isn't built. Posts in another app's format are found by
title and summary only. A delete that lands while that writer's first backfill
is mid-page can be indexed again by that page.

Decisions worth a second look

No stemmer. Every query word of two or more characters matches as a
prefix, so "garden" finds "gardens" and "gardening" in any language, and a
half-typed word finds its full form. Porter is English-only, and it stops
"runn" from finding "running". A single character matches only itself.
prefix='2 3' keeps short prefixes from scanning every term.
Highlights are plain text. FTS5 wraps matches in control characters, not
<mark>, and the page splits on them into text and <mark> nodes. The
writer's words are never parsed as HTML. The indexer strips those characters
from what it stores, so a post can't fake a highlight.
The search server function checks takedowns itself, author-level
included, because it can be called without the archive loader in front of it.

Verification

pnpm gate exit 0: 148 files, 2175 tests. One earlier run failed on
document-content.test.ts's 250 ms timing bound while the machine was loaded.
That test predates this branch and passed on the rerun.
pnpm build exit 0.
The search tests run against real SQLite FTS5 with every migration applied:
prefixes and accents, ranking, edits replacing old words, deletes, writer
scoping, hostile queries (", NOT, title:, (), takedowns, and the
backfill's races.
With the source at main and these tests checked out, four new test files
fail to load and 7 assertions fail in the existing suites (publish, edit,
delete, scheduled publish, account deletion, rights store). With the review
fixes' tests run against the commit before them, 24 fail.
Migration applied locally. pnpm db:generate reports no drift.

Review findings fixed in 60d0ecd:

A query's cost grew with every writer's posts.
The server function skipped the author-level takedown.
Posts in another app's format had dropped out of search.
A refusal halfway through the backfill marked a partial index complete, and a
slower tab could mark a finished one unfinished.
A title search over a failed listing said "No posts match".
The backup script assumed its own output format.

Fixed from the CodeRabbit review in 521f641: posts taken down one at a time
are now left out inside the search query, before the limit, so a run of them
can't push visible matches off the page. A failed search call falls back to the
title filter instead of failing the archive. Both have tests that fail on the
commit before.

Screenshots of the archive, results, empty result and title-only search, at
1440 and 390 px, are in the comment below.

…urvives it search_documents holds the text of each post this app writes. post_search, an FTS5 index over it, is external-content and kept in step by triggers. D1 refuses to export any database with a virtual table, so the nightly backup would have stopped working. scripts/d1-export.sh exports the ordinary tables by name, then appends what that leaves out: the virtual table, every index and trigger, and a rebuild of the index. The dump still restores with one execute --file. Migration 0016, applied locally. Signed-off-by: Peter Kibuchi <68213317+peterkibuchi@users.noreply.github.com>

Publishing, editing, scheduled publishing and deleting now update the index, best-effort after the record is live. Account deletion takes the index with it. Existing posts come in through /api/search/backfill, which the dashboard calls in the background, a page at a time, until the writer's repo is done. Search answers from the index only after that, so it never quietly misses older posts. Only documents this app can round-trip are indexed. Other authors' publications are not indexed at all. The index drops the porter stemmer. Every query word matches as a prefix, which covers plurals and suffixes in any language, and a half-typed word still finds its full form.

The archive's search box is now a GET form, so it works without JavaScript and a search is a link. An indexed writer gets full-text results ranked title first, with the matching passage quoted and the matches marked. Any other publication gets its newest page's titles and summaries filtered, and the page says that is what it searched. Searches are never cached. The read cache's key would have served the plain archive, and no purge can reach a page per query after a delete or takedown.

- The index carries each writer as one token, matched with every query. A search used to match every writer's posts and filter after the join, so its rows read grew with the whole corpus. A single-character word matches exactly, not as a prefix of every word, and 2- and 3-letter prefix indexes keep short prefixes cheap. - The search server function checks the author-level takedown itself, since it can be called without the archive loader. - Posts in another app's format are found by title and summary again. - The backfill never overwrites a post edited after its page was read. A slower tab can't undo a finished backfill, and a refusal halfway through the walk no longer marks a partial index complete. - A title search over a listing that failed says so, not "no posts match". Highlight markers are stripped from the fallback's titles. - The backup script guards every appended statement with IF NOT EXISTS, names FTS5 shadow tables exactly, and appends views. The workflow now proves each dump restores before uploading it. Signed-off-by: Peter Kibuchi <68213317+peterkibuchi@users.noreply.github.com>

📝 Walkthrough

This change adds per-writer full-text search for publications. It creates and backfills an FTS5 index, updates it as posts change, adds search to publication archives, and includes the index in account deletion and backup workflows.

Changes: Publication Search

Layer / File(s)	Summary
Search schema `src/db/schema.ts`, `drizzle/0016_post_search.sql`, `drizzle/meta/*`	Adds tables for search documents and backfill progress, an FTS5 index and synchronization triggers, and the related schema migration metadata.
Search engine and backfill `src/lib/search.ts`, `src/lib/search-query.ts`, `src/lib/search-backfill.ts`, `src/routes/api.search.backfill.ts`, `src/routes/dashboard.tsx`, `src/routeTree.gen.ts`, `src/__tests__/search*.test.ts`, `src/__tests__/search-backfill.test.ts`	Adds query parsing, document indexing, ranked search, paginated backfill, and a backfill endpoint invoked from the dashboard. Tests cover search, backfill, and endpoint behavior.
Publication indexing and account cleanup `src/routes/api.publish.ts`, `src/lib/publish-document.ts`, `src/lib/rights-store.ts`, `src/routes/api.account.delete.ts`, `src/__tests__/api-publish-*.test.ts`, `src/__tests__/publish-document.test.ts`, `src/__tests__/rights-store.test.ts`, `src/__tests__/api-account-delete-route.test.ts`	Publication edits and new posts add or update index entries; deletions remove entries. Account deletion removes that account’s search documents and backfill state.
Archive search interface `src/routes/@{$handle}.index.tsx`, `src/lib/read-cache.ts`, `src/lib/archive.ts`, `src/__tests__/archive-search.test.ts`	Adds indexed archive search with title-and-summary fallback, result highlighting, query-specific cache handling, and search-page metadata.
Search-aware backups `scripts/d1-export.sh`, `.github/workflows/backup.yml`, `docs/BACKUPS.md`	Adds an export script that includes virtual-table definitions and rebuild statements. The backup workflow restores and checks the dump in SQLite, and the documentation describes export and restore steps.

Merge Risk: 🔵 Low · up to 60d0e

Archive search may fail rather than fall back when a request fails, and hidden posts can crowd visible matches out of results. Both issues are bounded, but should be fixed or accepted before merging.

I hop through the posts at a brisk pace.
New words find their way to the index,
Old rows get swept out with care.
Backups tuck the search safely away.}
