-       An analysis handler that provides a breakdown of the analysis

-         <doc>
-           <field name="id">1</field>

-         <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
