773 | Note: Each document must contain a field which serves as the unique key. This key is used in the returned |
---|
774 | response to assoicate an analysis breakdown to the analyzed document. |

775 | |
---|
776 | Like the FieldAnalysisRequestHandler, this handler also supports query analysis by |
---|
777 | sending either an "analysis.query" or "q" request paraemter that holds the query text to be analyized. It also |
---|
778 | supports the "analysis.showmatch" parameter which when set to true, all field tokens that match the query |
---|
779 | tokens will be marked as a "match". |

784 | RequestHandler that provides much the same functionality as analysis.jsp. Provides the ability |
---|
785 | to specify multiple field types and field names in the same request and outputs index-time and |
---|
786 | query-time analysis for each of them. |
---|
787 | |
---|
788 | Request parameters are: |
---|
789 | analysis.fieldname - The field name whose analyzers are to be used |
---|
790 | analysis.fieldtype - The field type whose analyzers are to be used |
---|
791 | analysis.fieldvalue - The text for index-time analysis |
---|
792 | q (or analysis.q) - The text for query time analysis |
---|
793 | analysis.showmatch (true|false) - When set to true and when query analysis is performed, the produced |
---|
794 | tokens of the field value analysis will be marked as "matched" for every |
---|
795 | token that is produces by the query analysis |
