Gimantha, With Lucene 5.0 you can pass in an ExecutorService to the constructor of your IndexSearcher and it will search the segments in parallel if you use one of the IndexSearcher.search() methods that returns a TopDocs (and don't supply your own Collector).
The not-yet-released Lucene 5.1 includes some changes (LUCENE-6294 <https://issues.apache.org/jira/browse/LUCENE-6294>) that enable better parallel query support. --Terry On Tue, Apr 7, 2015 at 8:09 AM, Gimantha Bandara <giman...@wso2.com> wrote: > Hi all, > > As I can see the Multireader is reading the multiple indices sequentially > (correct me if I am wrong).
