Re: BooleanQuery

[Find Me]

For:
BooleanQuery bQuery=new BooleanQuery();
bQuery.add(messageQuery,true,false)

Use:
BooleanQuery bQuery=new BooleanQuery();
bQuery.add(messageQuery, BooleanClause.Occur.MUST);

Mapping is as follows:

For add(query, true, false) use add(query, BooleanClause.Occur.MUST)
For add(query, false, false) use add(query, BooleanClause.Occur.SHOULD)
For add(query, false, true) use add(query, BooleanClause.Occur.MUST_NOT)
