Hi all,
I want to speed up my searches by using multiple CPU cores for one
search. I saw that there is a possibility to use multithreaded search by
passing an ExecutorService to the IndexSearcher:
idxSearcher = new IndexSearcher(reader,
Executors.newCachedThreadPool());
I call my search using:
idxSearcher.search(query, filter, collector);
However, I found that this has no effect on search speed at all. After
some digging, I found out that the multithreading apparently does not
work when calling the search with a custom collector implementation, the
source code even says:
// TODO: should we make this
// threaded...? the Collector could be sync'd?
// always use single thread:
Does anyone know, whether there is work currently going on to address
this issue? If not, is there a workaround that allows me to use multiple
threads for searching and still use my own collectors?
Best regards,
Christoph Kaser
