Hello,
I am indexing books.
Fields are Title,Author, Subtitle, Category,Pages ...
Boosts are TitleBoost 1, AuthorBoost .8 SubtitleBoost .6;
Some one entered a query to search lets say Hitchhiker Guide
Now I want to show the reuslts in which both the words occur based on there
boost score.
I used
MultiFieldQueryParser queryParser = new MultiFieldQueryParser(new String[] {
Constants.TITLEminusAUTHOR,
Constants.AUTHOR_FIELD_NAME, Constants.SUBTITLEminusAUTHOR
}, new StandardAnalyzer());
queryParser.setDefaultOperator(OPERATOR_AND);
The problem comes is that I have author name Douglas Adams and If i search
for that as a query string its not returning any result. But if i remove
setDefaultOperator it returns all douglas Adams with the same query.

Hello,
I'm not sure what the question is. You may also want to include an
example of what you are doing.
Note that results are typically ordered based on the score of the match
for each result/hit, not purely the boost, unless you created your own
Similarity that ignores all other scoring factors except boost/lengthNorm.

Subject: Multi Field AND Search
Hi
I have indexed 8 fileds with different boost. Now i have given a
searchstring which consists of a words and phrases. Now i want to do AND
search of that searchString on four fields and show the result based on
boost. For me searchString should occur completely in one of the field
and
then the boosts come into picture. I know i can index combination of four
fields in one and then search in that but then the boost will not work.
Regards
Saurabh
