Multifield Search with OR and AND on different doc Fields
My requirement is to search on SEVEN Fields say F1,F2,F3,F4,F5,F6,F7 having
F1,F2,F3,F4 on one doc index
and F5,F6,F7 on a different doc index
I need to perform a search with ((F1=9 AND F2=4) AND (F3=keyword OR
F4=keyword)) OR (F5=9 AND F6=4 AND F7=keyword)
For normal search I was doing like this:
String[] sFields = { ID1, ID2, TITLE, CONTENT };
String[] sQuery = { id1, id2, sKeyword, sKeyword };
Occur[] flag = { BooleanClause.Occur.MUST, BooleanClause.Occur.MUST,
BooleanClause.Occur.MUST, BooleanClause.Occur.MUST };
Query oQuery = oMultiParser.parse(sQuery, sFields, flag, oAnalyzer) ;
Hits hits = indexSearcher.search(oQuery);
How can I modify the above query in such a way that it has to search on
different doc Indexes?

Do you hav some sort of problem with executing the code above? What
did you expect it to do and what was the results?

I'm sorry, but I don't understand your question.
You want to know how to search in another directory than the one
associated with your indexSearcher object?
