Thank you ag...@john.
This is even better. I don't have to bother about the 3rd argument, right?
I'll use the same one everytime for both registering a new core as well as
adding docs to an existing one.
Thanks,
KK.

Hi KK,
You're welcome!
BTW, I had a quick look at the Javadoc for IndexWriter and noticed this
constructor:
public IndexWriter(Directory d, Analyzer a)
"Constructs an IndexWriter for the index in d, first creating it if it
does not already exist."
I think that might solve your problem and
Unless something about your problem space *requires* that you reopen theindex,
you're better off just opining it once, writing all your documents to
it, then closing it. Although what you're doing will work, it's not very
efficient.
And the same thing is *especially* true of the searcher. There's
Thanks a lot @John. That solved the problem and the other advice is really
helpful. I'd have bumped over that otherwise.
This clarifies my doubt, that everytime I've to create a new index just call
the indexwriter with "true" thereby creating the directory, then start
adding docs with "false" as th
I think the problem is that you are creating an new index every time you
add a document:
IndexWriter writer = new IndexWriter(trueIndexPath, new
StandardAnalyzer(), true);
The last argument, the boolean 'true' tells IndexWriter to overwrite any
existing index in that directory. If you set that
Thank you very much.
I'm using the one mentioned by @Anshum ..but the problem is that after
indexing some no of docs what I see is only the last one indexed which
clearly indicates that the index is getting overwritten. I'm posing my
simple indexer and searcher herewith. Actually I'm trying to craw
Hi KK,
Easier still, you could just open the indexwriter with the last (3rd)
arguement as true, this way the indexwriter would create a new index as soon
as you start indexing. Also, if you just leave the indexWriter without the
3rd arguement, it'd conditionally create a new directory i.e. only if
You can do this with pure Java. Create a file object with the path you
want, check if it exists, and it not, create it:
File newIndexDir = new File("/foo/bar")
if(!newFileDir.exists()) {
newDirFile.mkdirs();
}
The 'mkdirs()' method creates any necessary parent directories.
If you want t
