SearcherManager mgr = new SearcherManager(dir, new MySearchWarmer());Can I put
null as the second parameter in the SearcherManager constructor?If not, how to
create a MySearchWarmer instance? The following explanation doesn't provide
sufficient info:
class MySearchWarmer implements SearchWarmer { @Override public void
warm(IndexSearcher searcher) throws IOException { // Run some diverse
searches, searching and sorting against all // fields that are used by
your application } }
