Bleve is a modern indexing and search library designed for Go. It allows developers to index various data structures, including text, numbers, and geospatial data, and perform efficient searches. Bleve offers intelligent defaults and a flexible configuration system based on Scorch. It addresses the challenge of building robust and scalable search functionality within Go applications by providing a comprehensive set of tools for indexing, querying, and analyzing data.
Bleve distinguishes itself through its comprehensive support for diverse data types, including geospatial and vector data, along with a rich set of query options like k-nearest neighbors search. Its configurable defaults and integration with Scorch simplify index management. The library also offers hybrid search capabilities, combining exact and semantic matching for enhanced accuracy and relevance.
- Data Type Support: Index text, numbers, geospatial data, and vectors with various field types.
- Query Capabilities: Perform term, phrase, fuzzy, and geospatial queries, including compound queries and result pagination.
- Scoring Models: Utilize TF-IDF and BM25 scoring models, along with hybrid scoring for improved search relevance.
- Text Analysis: Offers customizable analyzers and pre-built analyzers for multiple languages.
- Command-Line Interface: Includes a CLI tool for managing indexes, querying data, and performing other administrative tasks.
- Extensibility: Configurable defaults and support for custom analyzers facilitate tailoring Bleve to specific needs.
- Performance: Designed for high-performance indexing and searching with optimizations for scalability.
Bleve is a mature and actively developed project with a stable API and a strong community. Recent commits and a history of consistent releases indicate ongoing maintenance and support.
