Additional Query Parameters Stage
Table of Contents
The Additional Query Parameters query pipeline stage is used to set, append, and remove Solr query parameters. This stage takes a list of query parameters. Each parameter is specified as a triple consisting of parameter name, parameter value, and update policy.
Available update policies are: replace, append, remove and default.
The policy 'default' means that this parameter will be added only if it has not yet been set via the request or by a default specification in the Solr config file solrconfig.xml.
