will the solution provided by Charlie Hubbard do the work?
I am not sure I understand the "writer.addIndexes( ram );" part.
What if there are inconsistent data between FS an
nd some example that uses "Directory.write". But it doesn't look right to
me.

The two directories won't be synchronized. As the RAMDirectory JavaDocs
say:
Note that the resulting RAMDirectory instance is fully independent from the
original Directory (it is a complete copy). Any subsequent changes to the
originalDirectory will not be visible in the RAMDirectory instance.

what about my code as follow:
FSDirectory indexDir = new NIOFSDirectory(new File("c:/index_folder"));
Directory ramDir = new RAMDirectory(indexDir);
IndexWriterConfig iwc = new IndexWriterConfig(Version.LUCENE_35,
new StandardAnalyzer(Version.LUCENE_35));
IndexWriter iw = new IndexWriter(ramDir, i
You can always index into RAMDirectory for speed then synchronize those
changes to the disk by adding the RAMDirectory to a FSDirectory at some
point. Here is a simple example of how to do that:
public void save( RAMDirectory ram, File dir ) {
FSDirectory fs = FSDirectory.open( dir );
Hi,
Suppose that we have a huge amount of indices on hard drives but working in
RAMDirectory is a must, how can we decide which part of the indices to be
loaded into RAM, how to modify the indices, and when and how to synchronize
the indices with those on hard drives?
Any thoughts?
Thanks!
