Get query(search handler) configuration for a query using SolrJ

Question

Is it possible to get the query configuration values(default + request parameters) using SolrJ ?

For example: If I direct a request to the RequestHandler using SolrJ, I would like to get a list of parameters(default + overridden request parameters) used on the query. I need this to log the current configuration when the query was made.

Answer 1

Try adding the parameter echoParams=all.

The echoParams parameter tells Solr what kinds of Request parameters should be included in the response for debugging purposes, legal values include:

• none - don't include any request parameters for debugging
• explicit - include the parameters explicitly specified by the client in the request
• all - include all parameters involved in this request, either specified explicitly by the client, or implicit because of the request handler configuration.
