Provides the ability to specify multiple field types and field names in the same request. Expected parameters:

Name	Type	required	Description	Multi-valued
analysis.fieldname	string	no	When present, the text will be analyzed based on the type of this field name.	Yes, this parameter may hold a comma-separated list of values and the analysis will be performed for each of the specified fields
analysis.fieldtype	string	no	When present, the text will be analyzed based on the specified type	Yes, this parameter may hold a comma-separated list of values and the analysis will be performed for each of the specified field types
analysis.fieldvalue	string	no	The text that will be analyzed. The analysis will mimic the index-time analysis.	No
analysis.query OR q	string	no	When present, the text that will be analyzed. The analysis will mimic the query-time analysis. Note that the analysis.query parameter as precedes the q parameters.	No
analysis.showmatch	boolean	no	When set to true and when query analysis is performed, the produced tokens of the field value analysis will be marked as "matched" for every token that is produces by the query analysis	No

Note that if neither analysis.fieldname and analysis.fieldtype is specified, then the default search field's analyzer is used.

Note that if one of analysis.value or analysis.query or q must be specified
