Enhanced Full-Text Search and Advanced Query Debugging Features

​
Features

  • Enhanced Full-Text Search (FTS): Fuzzy Search & Boosting Now Available: it improves user experience with resilient, typo-tolerant searches and can surface the most contextually relevant results faster.
  • New SDK APIs:
    • explain_plan: Diagnose query performance and debug unexpected results by inspecting the execution plan.
    • analyze_plan: Analyze query execution metrics to optimize performance and resource usage. Such metrics include execution time, number of rows processed, I/O stats, and more.
    • restore: Revert to a specific prior version of your dataset and modify it from a verified, stable state.
  • Scalar Indexing for Extended Data Types: LanceDB now supports scalar indexing on UUID columns of FixedSizeBinary type.
  • Binary vector support in TypeScript SDK: LanceDB’s TypeScript SDK now natively supports binary vector indexing and querying with production-grade efficiency.
  • Support S3-compatible object store: Extended LanceDB Enterprise deployment to work with S3-compatible object stores, such as Tigris, Minio and etc. enterprise

​
Bug fix

  • Improved Merge insert performance: Enhanced the merge-insert operation to reduce error rates during upsert operations, improving data reliability.[lance#3603].
  • Batch Ingestion Error: Updated error codes for batch ingestion failures from 500 to 409 to accurately reflect resource conflict scenarios.
  • Cloud Signup Workflow Fix: Resolved an issue where users encountered a blank page after organization creation during the Cloud signup process.
  • Table Preview Data Display Issue: Fixed a bug causing the table preview page to show a generic “Something went wrong” error for datasets containing datetime columns, which previously prevented data inspection.
  • Rate Limit Error Clarity: Added explicit error messaging for system rate limits (e.g., API keys per table), replacing vague notifications that confused users.

​
Multivector Search ready and Table data preview available in Cloud UI

​
Features

  • Multivector Search is now live: documents can be stored as contextualized vector lists. Fast multi-vector queries are supported at scale, powered by our XTR optimization.
  • Drop_index added to SDK: users can remove unused or outdated indexes from your tables.
  • Explore Your Data at a Glance: preview sample data from any table with a single click. lancedb-cloud
  • Search by Project/Table in Cloud UI: allow users to quickly locate the desired project/table.lancedb-cloud

​
Bug fix

  • FTS stability fix: Resolved a crash in Full Text Search (FTS) during flat-mode searches.
  • prefilter parameter enforcement: Fixed a bug where the prefilter parameter was not honored in FTS queries.
  • Vector index bounds error: Addressed an out-of-bounds indexing issue during vector index creation.
  • distance_range() compatibility: Fixed errors when performing vector searches with distance_range() on unindexed rows.
  • Error messaging improvements: Replaced generic HTTP 500 errors with detailed, actionable error messages for easier debugging.
