Support OR in a Boolean Query

[milliondreams]

Is this already supported? Else we need to add this support.

I will try to explain using an example:

Let's assume that there are two clauses: Clause A and Clause B. Now the effect of the BooleanClause.Occur will be as follows:

In first case, both clause A and B have BooleanClause.Occur.Should flag set. This will imply that even if one of the clause is satisfied (A or B), then the document will be a hit.

In second case, clause A has BooleanClause.Occur.Must flag set and clause B has BooleanClause.Occur.Should flag set.

In this case, a document will be a hit when it "will" satisfy clause A. Whether this document satisfies clause B or not will have no effect on it being a hit.

But if the document does not satisfies clause A, then no matter whether it satisfies clause B or not, it will not be a hit.

In third case, both clause A and clause B have the BooleanClause.Occur.Must flag set.

In this case, a document will be a hit, only when it will satisfy "both" the clauses. If it will fail to satisfy even one of the clause, then it will not be a hit.

Will be a great help if you could put some JSON Queries explaining these examples...
