The Hybrid Query stage performs hybrid lexical-semantic search that combines BM25-type lexical search with KNN dense vector search via Solr.
ImportantThis stage is deprecated. Use Neural Hybrid Query Stage (5.9.10 and later) instead.

Query pipeline stage condition examples

Stages can be triggered conditionally when a script in the Condition field evaluates to true. Some examples are shown below. Run this stage only for mobile clients: 
params.deviceType === "mobile"
Run this stage when debugging is enabled: 
params.debug === "true"
Run this stage when the query includes a specific term: 
params.q && params.q.includes("sale")
Run this stage when multiple conditions are met: 
request.hasParam("fusion-user-name") && request.getFirstParam("fusion-user-name").equals("SuperUser");
!request.hasParam("isFusionPluginQuery")
The first condition checks that the request parameter “fusion-user-name” is present and has the value “SuperUser”. The second condition checks that the request parameter “isFusionPluginQuery” is not present.
