Subject Strange performance of Lucene 4.4.0
Date Sat, 07 Sep 2013 14:59:17 GMT
I am getting strange performance measures on Lucene 4.4.0, maybe someone can explain this:
The following syntax leads to pretty slow queries on my machine(16ms for every execution):, null, theSearcher.getIndexReader().maxDoc());
but the following syntax leads to an average execution time of 2ms:, null, theSearcher.getIndexReader().maxDoc(), new Sort());
Just by providing an empty Sort() instance, which does not sort at all! The executed query
is a simple TermQuery, the index contains about 2'000'000 documents. This is quite strange..
Thanks in advance
