for the query: <exp1> AND <exp2> OR <exp3> AND <exp4>
you could write this: bq.Add(<term for exp1>, BooleanClause.Occur.MUST); bq.Add(<term for exp2>, BooleanClause.Occur.MUST); bq.Add(<term for exp3>, BooleanClause.Occur.SHOULD); bq.Add(<term for exp4>, BooleanClause.Occur.MUST); but, if you ment the following: ( <exp1> AND <exp2> ) OR ( <exp3> AND <exp4> ) then you would write: bq1.Add(<term for exp1>, BooleanClause.Occur.MUST); bq1.Add(<term for exp2>, BooleanClause.Occur.MUST); bq2.Add(<term for exp3>, BooleanClause.Occur.MUST); bq2.Add(<term for exp4>, BooleanClause.Occur.MUST); bq3.Add(bq1, BooleanClause.Occur.SHOULD); bq3.Add(bq2, BooleanClause.Occur.SHOULD); and run the query using the composite boolean query "bq3". -- Neal -----Original Message----- From: Sudhanya Chatterjee [mailto:[EMAIL PROTECTED] Sent: Thursday, May 08, 2008 3:47 AM To: [email protected] Subject: Query with boolean operators Hi, How to create queries with Boolean operators for untokenized fields?
