From 1db4971da6a6c590856cd09af542c6e5f237093f Mon Sep 17 00:00:00 2001 From: perf3ct Date: Sat, 30 Aug 2025 18:26:31 +0000 Subject: [PATCH 01/13] feat(search): implement FST5 w/ sqlite for faster and better searching feat(search): don't limit the number of blobs to put in virtual tables fix(search): improve FTS triggers to handle all SQL operations correctly The root cause of FTS index issues during import was that database triggers weren't properly handling all SQL operations, particularly upsert operations (INSERT ... ON CONFLICT ... DO UPDATE) that are commonly used during imports. Key improvements: - Fixed INSERT trigger to handle INSERT OR REPLACE operations - Updated UPDATE trigger to fire on ANY change (not just specific columns) - Improved blob triggers to use INSERT OR REPLACE for atomic updates - Added proper handling for notes created before their blobs (import scenario) - Added triggers for protection state changes - All triggers now use LEFT JOIN to handle missing blobs gracefully This ensures the FTS index stays synchronized even when: - Entity events are disabled during import - Notes are re-imported (upsert operations) - Blobs are deduplicated across notes - Notes are created before their content blobs The solution works entirely at the database level through triggers, removing the need for application-level workarounds. fix(search): consolidate FTS trigger fixes into migration 234 - Merged improved trigger logic from migration 235 into 234 - Deleted unnecessary migration 235 since DB version is still 234 - Ensures triggers handle all SQL operations (INSERT OR REPLACE, upserts) - Fixes FTS indexing for imported notes by handling missing blobs - Schema.sql and migration 234 now have identical trigger implementations --- apps/server/src/assets/db/schema.sql | 209 ++++++ .../src/migrations/0234__add_fts5_search.ts | 513 +++++++++++++ apps/server/src/migrations/migrations.ts | 5 + apps/server/src/routes/api/import.ts | 3 + apps/server/src/routes/api/search.ts | 79 +- apps/server/src/routes/route_api.ts | 2 +- apps/server/src/services/app_info.ts | 2 +- apps/server/src/services/notes.ts | 8 + .../expressions/note_content_fulltext.ts | 166 +++++ .../src/services/search/fts_search.test.ts | 269 +++++++ apps/server/src/services/search/fts_search.ts | 680 ++++++++++++++++++ apps/server/src/services/search/note_set.ts | 4 + 12 files changed, 1937 insertions(+), 3 deletions(-) create mode 100644 apps/server/src/migrations/0234__add_fts5_search.ts create mode 100644 apps/server/src/services/search/fts_search.test.ts create mode 100644 apps/server/src/services/search/fts_search.ts diff --git a/apps/server/src/assets/db/schema.sql b/apps/server/src/assets/db/schema.sql index 07d924a915..887701167e 100644 --- a/apps/server/src/assets/db/schema.sql +++ b/apps/server/src/assets/db/schema.sql @@ -146,9 +146,218 @@ CREATE INDEX IDX_notes_blobId on notes (blobId); CREATE INDEX IDX_revisions_blobId on revisions (blobId); CREATE INDEX IDX_attachments_blobId on attachments (blobId); +-- Strategic Performance Indexes from migration 234 +-- NOTES TABLE INDEXES +CREATE INDEX IDX_notes_search_composite +ON notes (isDeleted, type, mime, dateModified DESC); + +CREATE INDEX IDX_notes_metadata_covering +ON notes (noteId, isDeleted, type, mime, title, dateModified, isProtected); + +CREATE INDEX IDX_notes_protected_deleted +ON notes (isProtected, isDeleted) +WHERE isProtected = 1; + +-- BRANCHES TABLE INDEXES +CREATE INDEX IDX_branches_tree_traversal +ON branches (parentNoteId, isDeleted, notePosition); + +CREATE INDEX IDX_branches_covering +ON branches (noteId, parentNoteId, isDeleted, notePosition, prefix); + +CREATE INDEX IDX_branches_note_parents +ON branches (noteId, isDeleted) +WHERE isDeleted = 0; + +-- ATTRIBUTES TABLE INDEXES +CREATE INDEX IDX_attributes_search_composite +ON attributes (name, value, isDeleted); + +CREATE INDEX IDX_attributes_covering +ON attributes (noteId, name, value, type, isDeleted, position); + +CREATE INDEX IDX_attributes_inheritable +ON attributes (isInheritable, isDeleted) +WHERE isInheritable = 1 AND isDeleted = 0; + +CREATE INDEX IDX_attributes_labels +ON attributes (type, name, value) +WHERE type = 'label' AND isDeleted = 0; + +CREATE INDEX IDX_attributes_relations +ON attributes (type, name, value) +WHERE type = 'relation' AND isDeleted = 0; + +-- BLOBS TABLE INDEXES +CREATE INDEX IDX_blobs_content_size +ON blobs (blobId, LENGTH(content)); + +-- ATTACHMENTS TABLE INDEXES +CREATE INDEX IDX_attachments_composite +ON attachments (ownerId, role, isDeleted, position); + +-- REVISIONS TABLE INDEXES +CREATE INDEX IDX_revisions_note_date +ON revisions (noteId, utcDateCreated DESC); + +-- ENTITY_CHANGES TABLE INDEXES +CREATE INDEX IDX_entity_changes_sync +ON entity_changes (isSynced, utcDateChanged); + +CREATE INDEX IDX_entity_changes_component +ON entity_changes (componentId, utcDateChanged DESC); + +-- RECENT_NOTES TABLE INDEXES +CREATE INDEX IDX_recent_notes_date +ON recent_notes (utcDateCreated DESC); + CREATE TABLE IF NOT EXISTS sessions ( id TEXT PRIMARY KEY, data TEXT, expires INTEGER ); + +-- FTS5 Full-Text Search Support +-- Create FTS5 virtual table for full-text searching +CREATE VIRTUAL TABLE notes_fts USING fts5( + noteId UNINDEXED, + title, + content, + tokenize = 'porter unicode61' +); + +-- Triggers to keep FTS table synchronized with notes +-- IMPORTANT: These triggers must handle all SQL operations including: +-- - Regular INSERT/UPDATE/DELETE +-- - INSERT OR REPLACE +-- - INSERT ...
