Hi Chris
actually for merging indices that's how Otis did it in the article I quoted:
// if -r argument was specified, use RAMDirectory
RAMDirectory ramDir = new RAMDirectory();
IndexWriter ramWriter = new IndexWriter(ramDir, analyzer, true);
addDocs(ramWriter, docsInIndex);
IndexWriter fsWriter = new IndexWriter(indexDir, analyzer, true);
fsWriter.addIndexes(new Directory[] { ramDir });
ramWriter.close();
fsWriter.close();
..which works great, and all I've done is replace the addDocs with my MySQL version of the function.
I do know about having to close and re-open to find the document count, which I've also tried but it didnt yield any difference,
a simple look in the index directory shows no files there except segements, even though it should've merged the RAMDir index into the fsDir.
thanks

: I would appreciate any feedback on my code and whether I'm doing : something in a wrong way, because I'm at a total loss right now : as to why documents are not being indexed at all.
I didn't try running your code (because i don't have a DB to test it with) but a quick read gives me a good guess as to your problem:
I believe you to call... ramWriter.close(); ...before you call... fsWriter.addIndexes(new Directory[] { ramDir });
(I've never played with merging indexes, so i could be completley wrong)
Everything I've ever read/seen/tried has indicated that untill you "close" your IndexWritter, nothing you do will be visible to anybody else who opens that "Directory"
I'm also guessing that when you were trying to add the docs to fsWriter directly, you were using an IndexReader you had opened prior to calling fsWriter.close() to check the number of docs ... that won't work for hte same reason.
