Dear All,
Now, I'm considering to build index for my application with lucene.
However, as the document sources I'm going to index has many duplications, so
before adding a document to an IndexWriter, I hope search in the index database
first to see if a same document copy has already been added. I used
IndexSearcher to search the same Dir while IndexWriter writing to it. However,
it seem that IndexSearcher returned no result though I'm sure there are
duplicate copies indexed already. And after the indexing procedure, I can get
the search results, so I'm sure I didn't write the wrong code. Anyone could
offer some help? Some example codes are appreciated.
Best
Wishes.
