You can extract org.apache.lucene.search.BooleanClause from BooleanQuery.
Something like:
if (contents instanceof BooleanQuery) {
BooleanQuery bq = (BooleanQuery) contents;
BooleanClause[] bclauses = bq.getClauses();
for (int i = 0; i < bclauses.length; i++) {
Query qc = bclauses[i].getQuery();
if
(bclauses[i].getOccur().equals(BooleanClause.Occur.MUST_NOT)) {
// NOT
}
else if
(bclauses[i].getOccur().equals(BooleanClause.Occur.MUST)) {
// AND
}
else if
(bclauses[i].getOccur().equals(BooleanClause.Occur.SHOULD)) {
// OR
}
}
}
Hope this helps.
