formalizing a query
Hi,
I need your help in formalizing this query:
(field1:query1 AND field2:query2) OR
(field1:query3 AND field2:query4) OR
(field1:query5 AND field2:query6) OR
(field1:query7 AND field2:query8) ... etc
Please give the code since I'm new to lucene
how we can use MultiFieldQueryParser or any parser to do the job
greatly appreciated

Hi,
I have done using this:
final QueryParser filterQueryParser = new QueryParser("", new
KeywordAnalyzer());
hits = indexSearcher.search(query, new
QueryWrapperFilter(filterQueryParser.parse(filterQuery)));
where filterQuery= "(field1:query1 AND field2:query2) OR (field1:query3 AND
field2:query4)"
If there are other methods that can do it in a professional way. please
comment.
Thanks

Hey,
I think u can try :
MultiFieldQueryParser.parse(String[] queries, String[] fields,
BooleanClause.Occur[] flags,
Analyzer analyzer)
The flags arrray will get u ORs and ANDs in places u need

Thanks for the help,
please provide the code to do that.
I tried with this one but it didn't work:
Query filterQuery = MultiFieldQueryParser.parse(new String{query1, query2,
query3, query4, .... }, new String{field1, field2, field1, field2, ... },
new KeywordAnalyzer());
this results in:
field1:query1 OR field2:query2 OR
field1:query3 OR field2:query4 ... etc
and NOT:
(field1:query1 AND field2:query2) OR
(field1:query3 AND field2:query4) ... etc
please help.

I *strongly* suggest you get a copy of Luke. It'll allow you to form queries
and see the results and you can then answer this kind of question as well
as many others.
Meanwhile, please see
