Description

Make it possible to define paramsets and use them directly in requests

example

curl http://localhost:8983/solr/collection1/config/params -H 'Content-type:application/json'  -d '{
"set" : {"x": {
              "a":"A val",
              "b": "B val"}
           },
"set" : {"y": {
               "x":"X val",
               "Y": "Y val"}
           },
"update" : {"y": {
               "x":"X val modified"}
           },

"delete" : "z"
}'
#do a GET to view all the configured params
curl http://localhost:8983/solr/collection1/config/params

#or  GET with a specific name to get only one set of params
curl http://localhost:8983/solr/collection1/config/params/x

This data will be stored in conf/params.json

This is used requesttime and adding/editing params will not result in core reload and it will have no impact on the performance

example usage http://localhost/solr/collection/select?useParams=x,y

or it can be directly configured with a request handler as follows

<requestHandler name="/dump1" class="DumpRequestHandler" useParams="x"/>

useParams specified in request overrides the one specified in requestHandler

A more realistic example

curl http://localhost:8983/solr/collection1/config/params -H 'Content-type:application/json'  -d '{
"set":{"query":{
    "defType":"edismax",
    "q.alt":"*:*",
    "rows":10,
    "fl":"*,score"  },
  "facets":{
    "facet":"on",
    "facet.mincount": 1
  },
 "velocity":{
   "wt": "velocity",
   "v.template":"browse",
   "v.layout": "layout"
 }
}
}

and use all of them directly is a requesthandler

  <requestHandler name="/browse" class="solr.SearchHandler" useParams="query,facets,velocity,browse"/>
