I want to grab some data from lucene index file. But I can't read it.
I try to use Luke
, but it always crashes with java.lang.OutOfMemoryError: Java heap space
. Note -Xmx
can't help me. I try -Xmx512, -Xmx1024 and even -Xmx2048.
I try to use Solr
also, but gets java.lang.OutOfMemoryError: Java heap space
too.
Any ideas how I can extract some data from Lucene?
P. S. I use lucene 2.3.0. My index file is 1.8 Gb size.
