It's not exactly clear what you want to achieve. You can use a servlet
filter to parse the query and modify the query. We do it that way. If
you are using solr in webapp then it should be easier for you to do
the same thing.

if you have already extendet the QParser class to handle the query ,
all that you need is to package the class into a jar file (i,e.  jar
contains package.pluginclass)

 and put the following lines in your solrconfig.xml

  <requestHandler name="qpname" class="package.pluginclass">
 	          <lst name="defaults">
 	                  <str name="echoParams">explicit</str>
	          </lst>
  </requestHandler>

send the query with the param wt=qpname to get the result
