how to avoid OutOfMemoryError while indexing ?
I found it is very easy to come into OutOfMemoryError.
My idea is that lucene could set the RAM memory Automatically，
but I couldn't find the API. My code:
IndexWriterConfig iwc = new IndexWriterConfig(Version.LUCENE_40, analyzer);
int mb = 1024 * 1024;
double ram = Runtime.getRuntime().maxMemory() / mb;
iwc.setRAMBufferSizeMB(ram);
but still OutOfMemoryError, can anyone help me ? thx

You should set your RAMBufferSizeMB to something smaller than the full
heap size of your JVM.
