I'm fairly new to lucene. The main reason why I did n't use the IndexReader constructor for the searcher is we organize the indexes as different partitions depending on document's date and during searching I instantiate a MultiSearcher object on these different partitions depending on from-date and to-date from the search. I was getting a runtime exception during search, If the index does not have any documents. That's why I was looking for some method on the searcher object that gives me the number of documents.
