> Create a request handler (actually a QParser) for use with user entered queries with following features-
> a) Take a user query string and try to match it against multiple fields, while recognizing sub-phrase matches.
> b) For each field give the below parameters:
> 1) phraseBoost - the factor which decides how good a n token sub phrase match is compared to n-1 token sub-phrase match.
> 2) maxScoreOnly - If there are multiple sub-phrase matches pick, only the highest
> 3) ignoreDuplicates - If the same sub-phrase query matches multiple times, pick only one.
> 4) disableOtherScoreFactors - Ignore tf, query norm, idf and any other parameters which are not relevant.
> c) Try to provide all the parameters similar to dismax. Reuse or extend dismax.
> Other suggestions and feedback appreciated :-)
