zoie 's RAMDirectory size

[genuine]

public IndexWriter openIndexWriter(Analyzer analyzer, Similarity
similarity) throws IOException {
if (_indexWriter != null)
return _indexWriter;

ZoieMergePolicy mergePolicy = new ZoieMergePolicy();
mergePolicy.setMergePolicyParams(_mergePolicyParams);
mergePolicy.setUseCompoundFile(false);

IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_34,
analyzer);
config.setOpenMode(OpenMode.CREATE_OR_APPEND);
config.setMergeScheduler(_mergeScheduler);
config.setMergePolicy(mergePolicy);

config.setReaderPooling(false);
if (similarity != null) {
config.setSimilarity(similarity);
}
config.setRAMBufferSizeMB(3);

IndexWriter idxWriter = new IndexWriter(_directory, config);
_indexWriter = idxWriter;
return idxWriter;
}



from the class :proj.zoie.impl.indexing.internal.RAMSearchIndex<R>

We can see the RAMDirectory's size is 3MB ,it 's setted by code.

If I set more than it (3MB), can I get more effective

This depends on your indexing rate.

The way to control how much to put in the memory index before flushing to disk is via the parameters (in ZoieConfig)

batchSize and batchDelay.

Flush occurs when either batchSize or batchDelay conditions are met.
