The useParams Parameter
When making a request, the useParams parameter applies the request parameters set to the request. This is
translated at request time to the actual params.
For example (using the names we set up in the earlier example, please replace with your own name):
http://localhost/solr/techproducts/select?useParams=myQueries
It is possible to pass more than one parameter set in the same request. For example:
http://localhost/solr/techproducts/select?useParams=myFacets,myQueries
In the above example the param set 'myQueries' is applied on top of 'myFacets'. So, values in 'myQueries'
take precedence over values in 'myFacets'. Additionally, any values passed in the request take precedence over
'useParams' params. This acts like the "defaults" specified in the ' ' definition in solrconfi
g.xml.
The parameter sets can be used directly in a request handler definition as follows. Please note that the
'useParams' specified is always applied even if the request contains useParams.
true
false
terms
To summarize, parameters are applied in this order:
parameters defined in in solrconfig.xml.
parameters applied in _invariants_ in params.json and that is specified in the requesthandler definition or
even in request
parameters defined in the request directly.
parameter sets defined in the request, in the order they have been listed with useParams.
parameter sets defined in params.json that have been defined in the request handler.
parameters defined in in solrconfig.xml.
Public APIs
The RequestParams Object can be accessed using the method SolrConfig#getRequestParams() . Each
paramset can be accessed by their name using the method RequestParams#getRequestParams(String
name).
