Variable: searchModeSchema
constsearchModeSchema:ZodEnum<{hybrid:"hybrid";keyword:"keyword";vector:"vector"; }>
How a query is matched. hybrid (the default) fuses vector similarity with
BM25 keyword ranking - the right choice for most search boxes and for source
data with exact identifiers (SKUs, error codes). vector is pure semantic
similarity; keyword is pure BM25 full-text (Beta on Databricks). The
value maps onto the serving API’s query_type (ANN / HYBRID).
