BoostBy []InstanceChatCompletionsParamsAISearchOptionsRetrievalBoostByOptional

Metadata fields to boost search results by. Overrides the instance-level boost_by config. Direction defaults to ‘asc’ for numeric/datetime fields, ‘exists’ for text/boolean fields. Fields must match ‘timestamp’ or a defined custom_metadata field.

Field string

Metadata field name to boost by. Use ‘timestamp’ for document freshness, or any custom_metadata field. Numeric and datetime fields support all four directions (asc, desc, exists, not_exists); text/boolean fields only support exists/not_exists.

maxLength64

minLength1

Direction InstanceChatCompletionsParamsAISearchOptionsRetrievalBoostByDirectionOptional

Boost direction. ‘desc’ = higher values rank higher (e.g. newer timestamps). ‘asc’ = lower values rank higher. ‘exists’ = boost chunks that have the field. ‘not_exists’ = boost chunks that lack the field. Optional — defaults to ‘asc’ for numeric/datetime fields, ‘exists’ for text/boolean fields.
