The documentation for the specific overload of MultiFieldQueryParser.Parse that you are using states the following:

IllegalArgumentException - if the length of the queries, fields, and flags array differ.

I suspect you are getting this exception as you have one query and 5 fields. If this is the method that you want to use, you must provide an array of queries with a length of five.

You may want to use a different parse overload, which will take a single query but multiple fields and flags.
