Key: SOLR-633
URL: https://issues.apache.org/jira/browse/SOLR-633
Project: Solr
Issue Type: New Feature
Components: search
Affects Versions: 1.3
Environment: All
Reporter: Preetam Rao
Priority: Minor
Fix For: 1.3
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 :-)
