The indexes and the generated column are written correctly, but as it stands this PR costs more than it saves.
searchPrompts has no callers. Search is still the client-side filter in Index.tsx, so both GIN indexes get built and neither is ever queried.
Meanwhile fts is a real column, so it now ships on every select('*'). That is getPrompt, getUserPrompts and getAllPrompts, which covers the detail page, profile pages, the feed, and the 50-row recommendations query. Every row carries a tsvector that nothing reads.
To land this, it needs both halves:
- Wire
searchPromptsinto Index.tsx, replacing the client-side filter, so the indexes actually get used. - Enumerate columns in those three selects instead of
*, softsstays server-side.
Also needs a rebase because #108 has changed all four files this touches.

Use server search when tags are selected.
When selectedTags is non-empty and searchQuery is empty, isSearch is false. The hook calls getAllPrompts(limit * 2), which returns only the newest rows before local tag filtering. With the default limit, older prompts that match the selected tags are omitted. Route tag-only selections through searchPrompts so its server-side overlaps('tags', tags) filter runs before the result limit. Add a tag-only hook test.

Preserve tag matches for free-text searches.
When isSearch is true, the local p.tags.some(...) predicate does not run. searchPrompts applies textSearch to fts, whose generated expression contains only title and prompt. Its separate overlaps('tags', tags) filter handles selected tags, not free-text tag matches. A prompt matched only by a tag is therefore omitted.
Include tag terms in the indexed fts document, or add an indexed server-side tag-match branch, so free-text searches preserve tag matches.

Preserve prior substring matches in searchPrompts.
The previous usePrompts path used case-insensitive substring checks on prompt titles and content. Non-empty queries now reach searchPrompts, which applies English websearch matching to the fts document. That document contains only title and prompt, and PostgreSQL full-text search matches normalized lexemes rather than arbitrary substrings. Partial-token or stop-word matches that the previous search returned can therefore be omitted.
Issue #102 requires results to be “at least as good as the ilike version.” Update searchPrompts or its search document to preserve the previous substring breadth with an indexed substring-compatible fallback or equivalent strategy. Add a regression test for a prior partial-token match.

Preserve ILIKE-compatible substring matches.
searchPrompts applies English websearch to the generated fts column. This performs full-text lexeme matching, not substring matching. The previous client-side filter matched cyber in Cyberpunk, but the new search omits that result. This violates Issue #102's requirement that database results be at least as good as the existing ILIKE behavior. Add an indexed substring-compatible fallback, such as a trigram-backed path, or obtain an explicit change to the requirement.

thanks @rahulkr182 ! Both review points are done.
searchPrompts is wired into the feed and the explicit column list keeps fts out of every response. 3 things before I can merge:
-
Rename the migration -
20260907120000is older than20260908000000and20260915120000, which are already applied in production, sodb pushwon't apply it. CI only passes because it builds from an empty database. Please rename it to a timestamp after20260915120000. -
Search now only matches whole words - The current search matches part of a word and also matches tag names. With
textSearch(..., { type: 'websearch' }), typing "cyber" no longer finds "cyberpunk" and "neo" no longer finds "neon", so search looks broken until the word is finished. Prefix matching fixes the typing case: build the tsquery yourself with:*on each term and calltextSearchwithouttype, so it usesto_tsquery. Please also keep tag names matching the search text, since that works today. -
Please debounce the search. The query text goes straight into the query key, so every keystroke fires a request, around 300ms is enough.
|
@rahulkr182 no pressure, but please let me know if you require any help for this, thanks for working over this! |

hi, sorry this sat for a while, main moved a lot since and this needs a rework now the big one: the prompt text is sign in only now, the db doesn't give the prompt column to signed out users at all. so PROMPT_SELECT_COLUMNS with prompt in it breaks the feed for everyone who isn't signed in. and the app doesn't load the prompt text with lists anymore even when signed in, only when you hit copy. check PROMPT_COLUMNS and getPromptText in prompts.ts on main. because of that the search can't go over the prompt text either. can you: build fts from title + tags only, not prompt |

When
ftsand the indexes do not already exist, adding the stored generated column rewritespublic.promptsunder anACCESS EXCLUSIVElock. Both regularCREATE INDEXstatements also block writes while they build. If writes must continue, replace the generated-column step with a staged maintained column and create both indexes withCREATE INDEX CONCURRENTLYthrough a migration path that runs outside the transaction. Otherwise, confirm the table size and schedule an appropriate maintenance window.🤖 Prompt for AI Agents

Search used websearch_to_tsquery, which only matches whole words, so "cyber" stopped finding "cyberpunk". Each word now becomes a prefix term, with tsquery syntax characters stripped so user input cannot make the query throw. Removing the sort in Index.tsx also dropped the trending score, leaving the hook's views-only sort. The score (views + copies * 3 + likes * 2) now lives in the hook. Also removes the unused PROMPT_SELECT_COLUMNS, which included the prompt column that signed-out selects cannot read, the leftover client-side search filter, and sets search_path on the migration's helper function.

Previously,
public.promptshad no full-text search index and no index on thetagsarray (text[]), meaning database search and tag filtering executed sequential table scans. Adding a generated tsvector column with a GIN index and a GIN index ontagsallows PostgreSQL to use fast Bitmap Index Scans (Bitmap Index Scan on prompts_fts_idxandBitmap Index Scan on prompts_tags_idx) for text search and array containment/overlap operations.How was it tested?
