Core Components: - Query AST with visitor pattern for both infix and MongoDB JSON formats - InfixQueryParser using recursive descent (Parlot dependency added) - MongoJsonQueryParser supporting all MongoDB query operators - QueryLinqBuilder for AST to LINQ transformation with NoSQL semantics - QueryParserFactory with auto-detection ({ = JSON, else infix) Search Services: - ISearchService interface (transport-agnostic) - SearchService orchestration (multi-node, parallel execution) - NodeSearchService (per-node search logic) - WeightedDiminishingReranker (algorithm from requirements) CLI Command: - km search command with all 13 flags (--nodes, --indexes, --format, etc.) - Output formats: table (default), json, yaml - Query validation with --validate flag - Comprehensive error handling Configuration: - SearchConfig with all defaults and complexity limits - NodeConfig.Weight for node ranking - SearchIndexConfig.Weight and Required for index management - Parlot NuGet package added to Directory.Packages.props FTS Index Updates: - SqliteFtsIndex schema updated to index title, description, content - Backward compatibility maintained with legacy IndexAsync(id, text) - New signature: IndexAsync(id, title, description, content) Tests (100+ test cases): - InfixQueryParserTests: 30+ test cases for all syntax - MongoJsonQueryParserTests: 25+ tests for MongoDB operators - QueryParserEquivalenceTests: 12+ tests ensuring both parsers equivalent - QueryLinqBuilderTests: 18+ tests for LINQ generation - RerankingTests: 10+ tests with explicit examples from requirements Code Quality: - 0 errors, 0 warnings build - GlobalSuppressions.cs for intentional design choices - .editorconfig for search-specific suppression rules - Comprehensive XML documentation - NoSQL semantics correctly implemented -

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes multiple critical bugs that prevented full-text search from working properly: 1. **Wrong IndexAsync signature** (ContentStorageService.cs) - Was calling legacy 2-param IndexAsync(contentId, content) - Now properly calls 4-param IndexAsync(contentId, title, desc, content) - This ensures title and description fields are indexed for search 2. **Incorrect phrase search syntax** (NodeSearchService.cs) - Phrase searches now use "phrase" instead of field:"phrase" - Single-word searches use field:term syntax - Fixes FTS5 compatibility issues with multi-word queries 3. **SQLite connections not disposed** (ContentService.cs + Commands) - Made ContentService IDisposable to properly close FTS connections - Updated all CLI commands to use 'using' statements - Ensures writes are flushed before process exits 4. **Force synchronous writes** (SqliteFtsIndex.cs) - Added PRAGMA synchronous=FULL for immediate persistence - Added WAL checkpoint on disposal to flush pending writes - Prevents data loss in short-lived CLI processes All search functionality now working correctly with proper FTS indexing of title, description, and content fields. 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- src/Core/Search/NodeSearchService.cs | 47 +++++++++++++++++------ src/Core/Search/SqliteFtsIndex.cs | 32 ++++++++++++++- src/Core/Storage/ContentStorageService.cs | 14 ++++++- src/Main/CLI/Commands/BaseCommand.cs | 4 +- src/Main/CLI/Commands/DeleteCommand.cs | 2 +- src/Main/CLI/Commands/GetCommand.cs | 2 +- src/Main/CLI/Commands/ListCommand.cs | 2 +- src/Main/CLI/Commands/SearchCommand.cs | 2 +- src/Main/CLI/Commands/UpsertCommand.cs | 2 +- src/Main/Services/ContentService.cs | 36 ++++++++++++++++- 10 files changed, 119 insertions(+), 24 deletions(-) diff --git a/src/Core/Search/NodeSearchService.cs b/src/Core/Search/NodeSearchService.cs index 148e5c9b9..ff30585d9 100644 --- a/src/Core/Search/NodeSearchService.cs +++ b/src/Core/Search/NodeSearchService.cs @@ -146,18 +146,29 @@ private string ExtractTerms(QueryNode node) private string ExtractTextSearch(TextSearchNode node) { - // Escape FTS5 special characters and quote the term - var escapedText = this.EscapeFtsText(node.SearchText);

Critical Bugs Fixed: - BM25 score normalization: SQLite FTS5 bm25() scores (range [-10,0]) are now properly normalized to [0,1] using exponential mapping. Previously, tiny scores (~0.000001) were filtered out by default MinRelevance=0.3. - SearchService.TotalResults: Now correctly reports total results before pagination (was incorrectly using paginated count). - MongoJsonQueryParser $text operator: Fixed operator precedence to check $text before other $ operators. - InfixQueryParser parenthesis validation: Added check for unmatched closing parenthesis after parse completes. - QueryLinqBuilder FTS field handling: Equal operator on FTS fields (content/title/description) now uses Contains semantics for full-text matching, not exact equality. - SearchCommand FTS index sharing: Search now uses the same FTS index instances registered with ContentStorageService, ensuring indexed data is accessible. Test Coverage Improvements: - Added 33 new tests (15 integration, 18 unit) - Coverage increased from 72.45% to 82.53% - All 472 tests passing, 0 skipped - Added comprehensive stemming verification tests proving run/running/runs matching works correctly - Added end-to-end integration tests exercising full CLI path - Fixed null reference warnings (CS8602), disposal warnings (CA2000), null conversion errors (CS8625) - Added GlobalUsings.cs with global using Xunit to test projects Why Tests Didn't Initially Catch Bugs: - Integration tests only verified exit codes, not actual result content - Functional tests explicitly used MinRelevance=0.0f, bypassing the filter that failed with default MinRelevance=0.3 - No test used default search settings that end users would encounter Files Modified: - Core: SqliteFtsIndex.cs, SearchService.cs, QueryLinqBuilder.cs, InfixQueryParser.cs, MongoJsonQueryParser.cs - Main: SearchCommand.cs, ContentService.cs, SearchIndexFactory.cs - Tests: Added 11 new test files, fixed existing test assertions --- AGENTS.md => CLAUDE.md | 0 .../Search/Query/Parsers/InfixQueryParser.cs | 13 +- .../Query/Parsers/MongoJsonQueryParser.cs | 12 +- src/Core/Search/Query/QueryLinqBuilder.cs | 16 + src/Core/Search/SearchConstants.cs | 6 + src/Core/Search/SearchService.cs | 2 +- src/Core/Search/SqliteFtsIndex.cs | 46 ++- src/Main/CLI/Commands/SearchCommand.cs | 10 +- src/Main/Services/ContentService.cs | 5 + src/Main/Services/SearchIndexFactory.cs | 2 +- tests/Core.Tests/Config/NodeConfigTests.cs | 1 -

Previously, field-specific queries like "content:summaries" would fail because ExtractComparison only handled Contains operator, not Equal. Since QueryLinqBuilder treats Equal on FTS fields as Contains (for FTS semantics), the FTS query extraction must do the same. This fix enables queries like: - km put "summary" && km search "content:summaries" ✅ (finds via stemming) - km put "connect" && km search "title:connection" ✅ (finds via stemming) Added 3 integration tests verifying field-specific stemming works.

New Test Coverage: - SearchEndToEndTests (Core): 25 tests verifying actual result data - Infix queries: simple, AND, OR, nested parentheses - MongoDB JSON queries: $and, $or, $text operator - Field-specific queries: content:, title:, description: - Stemming verification: summary/summaries, connect/connection - Multi-field complex queries with boolean logic - Cross-format equivalence (infix vs MongoDB JSON) - Pagination and TotalResults correctness - Regression tests for both critical bugs - SearchProcessTests (Main): 6 tests via actual process execution - Tests complete CLI path including argument parsing and JSON output - Verifies BM25 normalization with default MinRelevance=0.3 - Verifies field-specific stemming via CLI - Tests MongoDB JSON queries via process execution Why Previous Tests Were Inadequate: 1. Only checked exit codes, not actual results 2. Never tested with default MinRelevance (used 0.0f) 3. Never tested full pipeline integration 4.

Every example now has a corresponding E2E test that verifies it works. Examples Added: - Boolean operators: AND, OR (NOT documented as broken) - Complex queries with nested parentheses - MongoDB JSON query format with $and, $or, $text - JSON escaping for special characters - Field-specific searches: title:, content:, description: - Pagination and relevance filtering E2E Tests Added (15 process execution tests): - ExamplesCommandE2ETests: Tests every working example via subprocess - SearchProcessTests: 6 additional CLI process tests - All tests execute actual km binary and verify JSON output - Tests verify actual result data, not just exit codes New Bugs Discovered by E2E Tests: 1. NOT operator doesn't exclude matches correctly - "recipe NOT dessert" returns BOTH pasta AND dessert recipes - Affects both infix and likely MongoDB $not 2. Quoted phrases with operators don't work - '"Alice AND Bob"' fails - quotes don't escape operators properly 3. Field queries with quoted values fail - 'content:"user:password"' gives SQLite error "unknown special query" 4. Literal reserved words can't be searched - Searching for "NOT" causes "Unexpected end of query" error These bugs are documented in code comments and examples removed from km examples until fixes are implemented.

Filter out documents matching NOT terms + +**Files Affected:** +- `src/Core/Search/NodeSearchService.cs:190` - ExtractLogical NOT handling +- Need to add LINQ filtering after line 89 + +--- + +### 2. Quoted Phrases Don't Escape Operators + +**Status:** Known bug, not yet fixed + +**Issue:** Cannot search for literal phrases containing reserved words like "AND", "OR", "NOT". + +**Example:** +```bash +km put "Meeting with Alice AND Bob" +km search '"Alice AND Bob"' +# Expected: Find the document +# Actual: Parser error or incorrect results +``` + +**Root Cause:** +- Quoted strings should treat content literally +- Current parser/tokenizer doesn't properly handle operator escaping within quotes +- May be FTS query generation issue + +**Workaround:** Rephrase searches to avoid reserved words. + +**Fix Required:** Investigate tokenizer and FTS query extraction for quoted phrases. + +--- + +### 3. Field Queries with Quoted Values Fail + +**Status:** Known bug, not yet fixed + +**Issue:** Field-specific queries with quoted values containing special characters fail. + +**Example:** +```bash +km put "user:password format" +km search 'content:"user:password"' +# Expected: Find the document +# Actual: SQLite error "unknown special query" +``` + +**Root Cause:** +- Quoted values after field prefix (`content:"..."`) generate invalid FTS queries +- FTS syntax may not support this pattern +- Need investigation of FTS query generation + +**Workaround:** Search without field prefix or without quotes. + +--- + +### 4. Reserved Words Cannot Be Searched + +**Status:** Known limitation + +**Issue:** Cannot search for the literal words "AND", "OR", "NOT" even with quotes. + +**Example:** +```bash +km put "this is NOT important" +km search "NOT" +# Expected: Find the document +# Actual: Parser error "Unexpected end of query" +``` + +**Root Cause:** +- Tokenizer treats AND/OR/NOT as reserved keywords (case-insensitive) +- Even quoted, they're tokenized as operators +- Parser expects operands after NOT + +**Workaround:** None. These words cannot be searched. + +**Fix Required:** +- Tokenizer must recognize quotes and treat content literally +- Major parser refactoring needed + +--- + +## Testing Gaps + +These bugs were discovered through comprehensive E2E testing. Previous tests only verified: +- ✅ AST structure correctness +- ✅ LINQ expression building +- ✅ Direct FTS calls + +But did NOT test: +- ❌ Full pipeline: Parse → Extract FTS → Search → Filter → Rank +- ❌ Default settings (MinRelevance=0.3) +- ❌ Actual result verification + +**Lesson:** Exit code testing and structure testing are insufficient.
