Implements full-text search via inverted index structures that map tokenized terms to document IDs, supporting boolean operators (AND, OR, NOT), phrase matching with proximity constraints, and fuzzy matching via edit distance. The indexing pipeline tokenizes text fields during document ingestion and maintains a trie-based term dictionary for efficient prefix and wildcard queries. Query parsing converts user input into a query node tree (src/query_node.h) that is executed against the inverted index to return ranked results.
Unique: Uses a trie-based term dictionary with incremental indexing via Redis keyspace notifications (src/redis_index.c), enabling real-time index updates without batch reindexing, unlike traditional search engines that require explicit commit/refresh cycles
vs alternatives: Faster than Elasticsearch for sub-million-document workloads because it avoids network round-trips and leverages Redis' in-memory architecture; simpler operational model than Solr with no separate JVM process
Implements vector similarity search by supporting multiple approximate nearest neighbor (ANN) algorithms: FLAT (brute-force), HNSW (Hierarchical Navigable Small World), and SVS (Streaming Vector Search). Vectors are indexed as VECTOR field types during document ingestion and stored in specialized index structures. Query execution performs similarity search using cosine, L2, or inner product distance metrics, returning top-k nearest neighbors ranked by distance. The module integrates with Redis' native data types, storing vectors as binary blobs in hashes or JSON documents.
Unique: Supports three distinct ANN algorithms (FLAT, HNSW, SVS) selectable per index, with HNSW using hierarchical graph structure for logarithmic query complexity; integrates vector search directly into Redis' command protocol via FT.SEARCH with VECTOR clause, eliminating separate vector DB round-trips
vs alternatives: Faster than Pinecone/Weaviate for sub-million-vector workloads because vectors live in the same Redis instance as source data, eliminating network latency; more operationally simple than Milvus because it's a single Redis module with no separate infrastructure
Implements thread-safe concurrent query execution using reader-writer locks and atomic operations. Multiple queries can execute concurrently on the same index (read-only operations), while index modifications (document addition/deletion) acquire write locks to prevent concurrent modification. The module uses Redis' threading model and integrates with Redis' event loop for non-blocking execution. Garbage collection (src/spec.c) runs asynchronously to clean up deleted documents without blocking queries.
Unique: Uses reader-writer locks to allow concurrent read-only queries while serializing write operations, integrated with Redis' event loop for non-blocking execution; garbage collection runs asynchronously to avoid blocking queries during cleanup
vs alternatives: More efficient than global locking because read-only queries don't block each other; simpler than optimistic locking because Redis' single-threaded event loop simplifies synchronization
Integrates with Redis' persistence and replication mechanisms to ensure indexes survive server restarts and are replicated to replica nodes. Index structures are serialized during RDB snapshots and deserialized on startup. For replication, index modifications are propagated to replicas via Redis' replication stream, ensuring replicas maintain consistent indexes. The module registers custom Redis types (IndexSpecType, InvertedIndexType) to enable proper serialization/deserialization.
Unique: Registers custom Redis types (IndexSpecType, InvertedIndexType) for proper serialization in RDB snapshots; integrates with Redis' replication stream to propagate index modifications to replicas without explicit replication logic
vs alternatives: Simpler than external backup systems because indexes are included in Redis' native RDB snapshots; more reliable than application-level index rebuilding because replication ensures replicas have consistent indexes
Implements relevance scoring using BM25 algorithm (Okapi BM25) for full-text search results, with configurable parameters (k1, b) for tuning. Field-level weights can be specified at index creation time to boost relevance of certain fields (e.g., title weighted higher than description). Results are ranked by BM25 score, with ties broken by document ID. The scoring system integrates with query execution to compute scores during result collection.
Unique: Implements BM25 scoring with field-level weights specified at index creation, enabling domain-specific relevance tuning without custom scoring logic; integrates scoring into query execution to compute scores during result collection rather than post-processing
vs alternatives: More efficient than Elasticsearch's custom scoring because BM25 is computed in-process without script execution; simpler than learning Elasticsearch's scoring DSL because field weights are declarative
Implements text processing pipeline for TEXT fields including tokenization (splitting text into terms), lowercasing, stopword removal, and stemming (reducing words to root form). Tokenization rules are specified at field creation time and applied during document indexing. The module supports multiple stemming algorithms (Porter stemmer) and configurable stopword lists. Tokenized terms are stored in the inverted index for efficient full-text search.
Unique: Applies tokenization and stemming during document indexing (not at query time), enabling efficient full-text search without per-query processing; supports configurable stemming algorithms and stopword lists at field creation time
vs alternatives: More efficient than query-time stemming because terms are pre-processed during indexing; simpler than Elasticsearch's analyzer chains because tokenization rules are declarative
Implements numeric range queries using a numeric range tree data structure (src/spec.h) that indexes NUMERIC field types for efficient range filtering. Queries specify min/max bounds and return documents within the range. The module also supports numeric aggregations (SUM, AVG, MIN, MAX, COUNT) via the aggregation framework (src/aggregate/aggregate.h), which processes result sets through a pipeline of reduction operators. Numeric fields are indexed separately from text, enabling fast range scans without full-text index overhead.
Unique: Uses a specialized numeric range tree (not a B-tree or skip list) optimized for Redis' in-memory model, combined with aggregation pipeline that supports expression evaluation (src/result_processor.h) for computed fields during aggregation, enabling complex numeric transformations without post-processing
vs alternatives: Faster than SQL databases for numeric range queries on indexed fields because the range tree is optimized for in-memory traversal; more flexible than simple hash-based filtering because it supports arbitrary range bounds without pre-computed buckets
Implements geospatial search via GEO field type for latitude/longitude-based queries and GEOMETRY field type for complex spatial shapes. GEO fields use geohashing to index points and support radius searches (e.g., 'find all restaurants within 5km'). GEOMETRY fields support polygon/linestring queries for more complex spatial relationships. Both field types are indexed separately and integrated into the query execution engine, allowing spatial filters to be combined with text and numeric filters in a single query.
Unique: Uses geohashing for GEO field indexing, enabling efficient radius searches without requiring separate geospatial indexes; GEOMETRY support via WKT parsing allows complex spatial queries without external GIS libraries, all integrated into the same query execution engine as text and numeric search
vs alternatives: Simpler operational model than PostGIS because geospatial data lives in Redis without a separate database; faster than Elasticsearch geo queries for small-to-medium datasets because it avoids Elasticsearch's inverted index overhead for spatial data
