Filter - Explicit interface implementation in VectorStoreTextSearch ### Dual-Path Architecture Two independent code paths, no translation layer: Legacy path (non-generic): - ITextSearch with TextSearchOptions and TextSearchFilter (clause-based) - Uses VectorSearchOptions.OldFilter (obsolete) with pragma warning suppression - No dynamic code, AOT compatible - 10 existing tests unchanged Modern path (generic): - ITextSearch with TextSearchOptions and Expression filter - Uses VectorSearchOptions.Filter (LINQ native, not obsolete) - No dynamic code, AOT compatible - 7 new tests ## Changes - Added ITextSearch interface and TextSearchOptions class - Implemented dual interface in VectorStoreTextSearch - Deleted ~150 lines of Option 2 translation layer code - Removed all RequiresDynamicCode attributes - Removed DynamicallyAccessedMemberTypes.PublicMethods from 5 locations: - VectorStoreTextSearch.cs - TextSearchServiceCollectionExtensions.cs (3 methods) - TextSearchKernelBuilderExtensions.cs (1 method) - Deleted 7 Option 2 translation tests - Added 7 LINQ filtering tests - Added DataModelWithTags to test base - Reverted Program.cs to original state ## Files Changed 8 files, +144 insertions, -395 deletions - ITextSearch.cs - TextSearchOptions.cs (added generic class) - VectorStoreTextSearch.cs (removed translation layer, added dual interface) - TextSearchServiceCollectionExtensions.cs (removed PublicMethods annotation) - TextSearchKernelBuilderExtensions.cs (removed PublicMethods annotation) - VectorStoreTextSearchTestBase.cs (added DataModelWithTags) - VectorStoreTextSearchTests.cs (removed 7 tests, added 7 tests) - Program.cs in AotTests (removed suppression, restored tests) --- .../Data/TextSearch/ITextSearch.cs | 14 +- dotnet/src/SemanticKernel.AotTests/Program.cs | 7 +- .../Search/VectorStoreTextSearchTests.cs | 3 - .../TextSearchKernelBuilderExtensions.cs | 2 +- .../TextSearchServiceCollectionExtensions.cs | 6 +- .../Data/TextSearch/VectorStoreTextSearch.cs | 169 +-------- .../Data/VectorStoreTextSearchTestBase.cs | 2 + .../Data/VectorStoreTextSearchTests.cs | 336 +++++++----------- 8 files changed, 143 insertions(+), 396 deletions(-) diff --git a/dotnet/src/SemanticKernel.Abstractions/Data/TextSearch/ITextSearch.cs b/dotnet/src/SemanticKernel.Abstractions/Data/TextSearch/ITextSearch.cs index 59eb45e08d13..496a60c13187 100644 --- a/dotnet/src/SemanticKernel.Abstractions/Data/TextSearch/ITextSearch.cs +++ b/dotnet/src/SemanticKernel.Abstractions/Data/TextSearch/ITextSearch.cs @@ -8,6 +8,7 @@ namespace Microsoft.SemanticKernel.Data; /// /// Interface for text based search queries with type-safe LINQ filtering for use with Semantic Kernel prompts and automatic function calling. +/// This generic interface supports LINQ-based filtering through for type-safe queries. /// /// The type of record being searched.
