Which Analyzer have you assigned per field?
The PerFieldAnalyzerWrapper uses a default analyzer (the one you passed
during its construction), and then you assign specific analyzers to each
field that you want to have special treatment.
For example:
PerFieldAnalyzerWrapper aWrapper = new PerFieldAnalyzerWrapper(
new StandardAnalyzer());
aWrapper.addAnalyzer("data", new MGIAnalyzer());
aWrapper.addAnalyzer("sdata", new StemmedMGIAnalyzer());
Now, for the fields in question, have you assigned an Analyzer that
doesn't actually use stopwords? (there are several available in core)
Or are you perchance using a custom Analyzer that doesn't process stop
words?
Could you possibly post your Initialization code for this? If so I
think we could be of more help to you.

Hi,
From whatever you have written you are trying to write a query
*word1 AND stopword AND word2
*this means that the result should contain all of word1, word2 and the
stopword.
Since you have already removed the stopword during index time you will never
find any document matching your query. (this is expected behaviour)
you can possibly use word1 OR stopword OR word2 (depends on what you want in
the result)
If you can clarify more about what you want in the result we can discuss on
what can be done.
I wanted MultiFieldQueryParser to ignore any stopword the user may type
in. In that particular case I'd like the result to be word1 AND word2. I
thought that was what would happen because I pass the Analyzer to
MultiFieldQueryParser, so I expected the parser to ignore stopwords for
fields which the analyzer drops stopwords (I use PerFieldAnalyzerWrapper
analyzer).

Hello,
I used an Analyzer which removes stopwords when indexing, then I wanted
to do an AND search using MultiFieldQueryParser. So I did this:
word1 AND stopword AND word2
I thought the stopword would be ignored by the searcher (I use the same
Analyzer to index and search). But instead, I get no results whenever I
have a stopword like that. If I remove the stopword, giving me:
word1 AND word2
then the search is sucessful. Is that the expected behaviour? Am I
doing something wrong?
