QueryDocumentRequestMetadataFilters Property

Filter for RelevantChunk metadata. Each MetadataFilter object should correspond to a unique key. Multiple MetadataFilter objects are joined by logical "AND"s.
Note: Document-level filtering is not supported for this request because a Document name is already specified.
Example query: (year >= 2020 OR year < 2010) AND (genre = drama OR genre = action)
MetadataFilter object list: metadataFilters = [ {key = "chunk.custom_metadata.year" conditions = [{int_value = 2020, operation = GREATER_EQUAL}, {int_value = 2010, operation = LESS}}, {key = "chunk.custom_metadata.genre" conditions = [{stringValue = "drama", operation = EQUAL}, {stringValue = "action", operation = EQUAL}}]
Example query for a numeric range of values: (year > 2015 AND year <= 2020)
MetadataFilter object list: metadataFilters = [ {key = "chunk.custom_metadata.year" conditions = [{int_value = 2015, operation = GREATER}]}, {key = "chunk.custom_metadata.year" conditions = [{int_value = 2020, operation = LESS_EQUAL}]}]
Note: "AND"s for the same key are only supported for numeric values. String values only support "OR"s for the same key.
