Package com.redis.vl.query

Class AggregateHybridQuery

java.lang.Object
com.redis.vl.query.AggregateHybridQuery
public final class AggregateHybridQuery extends Object
AggregateHybridQuery combines text and vector search in Redis using aggregation.

This is the primary name for hybrid queries in RedisVL, matching the Python implementation. It is a type alias for HybridQuery.

Ported from Python: redisvl/query/aggregate.py:57-315 (AggregateHybridQuery class)

It allows you to perform a hybrid search using both text and vector similarity. It scores documents based on a weighted combination of text and vector similarity.

Python equivalent: 

 query = AggregateHybridQuery(
     text="example text",
     text_field_name="text_field",
     vector=[0.1, 0.2, 0.3],
     vector_field_name="vector_field",
     text_scorer="BM25STD",
     filter_expression=None,
     alpha=0.7,
     dtype="float32",
     num_results=10,
     return_fields=["field1", "field2"],
     stopwords="english",
     dialect=2,
 )
 results = index.query(query)

Java equivalent: 

 HybridQuery query = AggregateHybridQuery.builder()
     .text("example text")
     .textFieldName("text_field")
     .vector(new float[]{0.1f, 0.2f, 0.3f})
     .vectorFieldName("vector_field")
     .textScorer("BM25STD")
     .filterExpression(null)
     .alpha(0.7f)
     .dtype("float32")
     .numResults(10)
     .returnFields(List.of("field1", "field2"))
     .stopwords(HybridQuery.loadDefaultStopwords("english"))
     .dialect(2)
     .build();
 List<Map<String, Object>> results = index.query(query);
