You also do the full query with one level of BooleanQuery by using the
BooleanQuery#setMinimumNumberShouldMatch(int min) method. The default
minimum number of optional clauses to match is zero, but you can set it to 1
for your case. I don't know if there is any difference in performance or
scoring between these two approaches.
Using Solr, it's the "mm" request parameter.

Subject: How to use complicated boolean query?
I want to implement a query in Solr like the follow
((X OR Y) AND Z) … ((X ∨ Y) ∧ Z)
BooleanQuery q = new BooleanQuery();
BooleanQuery inner = new BooleanQuery();
inner.add(X, Occur.SHOULD);
inner.add(Y, Occur.SHOULD);
q.add(inner, Occur.MUST);
q.add(Z, Occur.MUST);
For example, I want to query
(Field1=X or Field1=Y ) and Field2=Z
Thanks!
