The Query Stages API provides endpoints to:
  • List query stage configuration properties
  • Manage query stage instances
  • Test processing on a set of queries

​
Examples

See all defined query pipeline stages, regardless of type: REQUEST 
curl -u USERNAME:PASSWORD https://FUSION_HOST:8764/api/query-stages/instances
RESPONSE 
[{
  "type" : "query-logging",
  "id" : "detailed-logging",
  "detailed" : true,
  "skip" : false,
  "label" : "detailed-query-logging",
}]
Add a new query stage: REQUEST 
curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d'{ "type" : "query-logging", "id" : "detailed-logging", "detailed" : true }' https://FUSION_HOST:8764/api/query-stages/instances
RESPONSE 
 {
  "type" : "query-logging",
  "id" : "detailed-logging",
  "detailed" : true,
  "skip" : false,
  "label" : "query-logging"
}
Update a query stage: REQUEST 
curl -u USERNAME:PASSWORD -X PUT -H 'Content-type: application/json' -d'{ "type" : "query-logging", "id" : "detailed-logging", "detailed" : true, "label" : "detailed-query-logging" }' https://FUSION_HOST:8764/api/query-stages/instances/detailed-logging
RESPONSE 
{
  "type" : "query-logging",
  "id" : "detailed-logging",
  "detailed" : true,
  "skip" : false,
  "label" : "detailed-query-logging",
}
Note that all required elements must be included in the update. Delete a query stage: REQUEST 
curl -u USERNAME:PASSWORD -X DELETE https://FUSION_HOST:8764/api/query-stages/instances/detailed-logging
No response is returned. To check that the stage is no longer defined, list all query stage instances. Test that a set-params stage defines properties correctly: REQUEST 
curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d '{"type":"set-params", "params":[{"key":"rows", "value":"2", "policy":"append"}]}' https://FUSION_HOST:8764/api/query-stages/solr/test?q=*:*
