       http://wiki.apache.org/solr/AnalysisRequestHandler

       An analysis handler that provides a breakdown of the analysis

       content stream with the following format:

       <docs>

         <doc>...</doc>

         ...

    Note: Each document must contain a field which serves as the

    unique key. This key is used in the returned response to associate

    an analysis breakdown to the analyzed document.

    Like the FieldAnalysisRequestHandler, this handler also supports

    query analysis by sending either an "analysis.query" or "q"

    request parameter that holds the query text to be analyzed. It

    also supports the "analysis.showmatch" parameter which when set to

    true, all field tokens that match the query tokens will be marked
