Can't open lucene index (Java heap space)
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: J开发者_如何学Goava 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.
What size is the data you are trying to fetch? Maybe the result set is too large to handle?
I create my own simple lucene client, based on org.apache.lucene.search.Searcher
. And grab data that I want.
