Subject Re: [jira] Commented: (LUCENE-565) Supporting deleteDocuments in IndexWriter (Code and Performance Results Provided)
Date Wed, 12 Jul 2006 16:29:05 GMT
No, the code does not exist yet... I have a version that requires a  
unique identifier.

I proposed a design of "BufferedWriter" in a previous email that  
would not have this limited. It is similar to what other have  
suggested, which is to handle the buffering in a higher-level class  
and level IndexWriter alone.

The design involved a temporary ram directory, and ordered lists of  
commands (so that deletes and inserts can be interleaved).
