Hi,

Do you mean that your query phrase is "Health Safety",
but docs with "Health and Safety" returned?

If that is the case, the reason is that StandardAnalyzer
filters out "and" (also "or, "in" and others) as stop 
words during indexing, and the QueryParser filters those
words out also.

Best regards, Lisheng

Subject: Phrase Query Problem



I have the following code for search:

BooleanQuery bQuery = new BooleanQuery();
Query queryAuthor;
queryAuthor = new TermQuery(new Term(IFIELD_LEAD_AUTHOR,
author.trim().toLowerCase()));
bQuery.add(queryAuthor, BooleanClause.Occur.MUST);
....................................................................
....................................................................

PhraseQuery pQuery = new PhraseQuery();
String[] phrase = txtWithPhrase.toLowerCase().split(" ");
for (int i = 0; i < phrase.length; i++) {
	pQuery.add(new Term(IFIELD_TEXT, phrase[i]));
}
pQuery.setSlop(0);
bQuery.add(pQuery, BooleanClause.Occur.MUST);
....................................................................
....................................................................

String[] sortOrder = {IFIELD_LEAD_AUTHOR, IFIELD_TEXT};
Sort sort = new Sort(sortOrder);
hits = indexSearcher.search(bQuery, sort);

Now My problem here is: If I do a search on a phrase with text Health
Safety, it is fetching me all the records where in the text is Health
and/or/in Safety. It is fetching me these records even after setting the
slop of the phrase query to zero for exact match. I am using standard
analyzer while indexing my records.

Any help on this is greatly appreciated.
