: Hits hits = indexSearcher.search(searchQuery, filter) // here I want
: to pass multiple filter... (DateFilter,QueryFilter)
You can write a Filter that takes in multiple filters and ANDs them together (or ORs them, it's not clear what you want)
Hits h = s.search(q,new AndFilter(df,qf));
(I'm planing on writting a generalized "BooleanFilter" class sometime in the next few weeks)
Wait.... there already is a ChainedFilter in the Lucene Sandbox. Here's a test case I wrote for it for Lucene in Action (the test case is in the sandbox also):
public void testAND() throws Exception {
ChainedFilter chain = new ChainedFilter(
new Filter[] {dateFilter, bobFilter}, ChainedFilter.AND); Hits hits = searcher.search(query, chain);
assertEquals("AND matches just bob", MAX / 2, hits.length());
assertEquals("bob", hits.doc(0).get("owner"));
}(you'll need to see the setUp method to make sense of the asserts, though).

The test cases are here:

It's obviously a bit more complicated than a simple AND, though, but does that simple case as well.
