This code adds the same query twice to a boolean query:
Query query =
parser.parse(searchString);
bq1.add(query,
BooleanClause.Occur.MUST);
bq1.add(new BooleanClause(query,
BooleanClause.Occur.MUST));
But X AND X == X :-)
You probably want to do something like:
Query q = new BooleanQuery();
bq.add(parser.parse(searchString1), BooleanClause.Occur.MUST);
bq.add(parser.parse(searchString2), BooleanClause.Occur.MUST);
...
searchHits = searcher.search(q);
