How to check, whether Index is optimized or not?
Hello dear Lucene users!
Is their an easy way to check, whether index is optimized or not?
Best regards,
Max

A fully optimized index has only a single segment. If you're using
the non-compound index format you will be able to tell by looking at
the segments file in the index where only one segment would be
listed. There are certainly programatic ways of telling too, but I
don't have that detail handy at the moment.

I don't think so. It's still a single segment. Close the reader, and you still have only one segment. You only have gaps from deleted docs, but I think that doesn't make the index unoptimized, even though optimizing such an index will remove the gaps.

Do we need to check if any documents are marked for deletion?

Actually, I think you rather need the following:
public boolean isOptimized() {
return segmentInfos.size() == 1 && !hasDeletions();
}

I don't think we have a public API for that, but the index is considered optimized when it contains only a single segment.
Then, we could add the following to IndexReader:
public boolean isOptimized() {
return segmentInfos.size() == 1;
}
I think that should do it.
