about ParallelMultiSearcher
Hello all,
I am doing some search work using Lucene 1.4 paralmultisearch.
If I use MultiSearcher.It works well.
But if I use ParallelMultisearcher the code can compile correctly and
cann't execute correctly.The executing error is as following:
Exception in thread "main" java.lang.NoSuchMethodError:
org.apache.lucene.search.ParallelMultiSearcher.getStarts()[I
at
org.apache.lucene.search.ParallelMultiSearcher.<init>(ParallelMultiSe
archer.java:38)
at SearchFiles.main(SearchFiles.java:92)
Is there anyone know something about it?
Thanks,
Li

I'm using ParallelMultiSearcher just fine, with all versions of Lucene
1.3 and beyond. I'm using CVS HEAD at the moment, not an official 1.4
RC release.
I suspect you have an old Lucene JAR file in your classpath.

ParallelMultiSearcher simply spins a separate thread for each index and
waits for the results from all threads before returning results.
Depending on your hardware, you may or may not receive performance
benefits over using plain MultiSearcher. You would likely need each
index on a separate disk so that you would benefit from parallel I/O.
Beyond standard multi-threaded Java concerns, there is nothing special
about ParallelMultiSearcher, and tuning would be dependent on your
environment.

Hello all,
What requirements ParallelMultiSearch to JVM? What the adjustments of
memory and for processes of system are required? If it somebody knows,
let it can be on an example anyone of Unix System.
Is there anyone know something about it?
Thanks,
Vladimir
