Hi all,
I am passing from Neo4j 1.9.9 to Neo4j 2.2.0, with embedded mode using
java. I have inserted the transactions also for read operations, but now
when I query my Lucene indexes as this
rhits = index.query("cs", "*");
out.println("#" + rhits.size());
rhits.close();
as you can see I do not have to iterate over the result, I need only the
number of results but this new Neo4j version looks like loading all in
memory and I get the following error in the first instruction.
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

I never get this with older versions of Neo4j! I always did this operation
until version 1.9.9.
Could you please help me to avoid this? Is it a bug of library
implementation or I have to change the way of querying?
Thanks in advance,
Rita
