Subject Re: Proposal about Version API "relaxation"
Date Thu, 15 Apr 2010 20:50:18 GMT
Robert ... I'm sorry but changes to Analyzers don't *force* people to
reindex. They can simply choose not to use the latest version. They can
choose not to upgrade a Unicode version. They can copy the entire Analyzer
code to match their needs. Index format changes is what I'm worried about
because that *forces* people to reindex.

Analyzers, believe it or not, are just a tool, an out of the box tool even,
we're giving users to analyze their stuff. Probably a tool used by most of
our users, but not all. Some have their own tools, that are currently
wrapped as a Lucene Analyzer just because the API mandates. But we were
talking about that too recently no? Ripping Analyzer off IndexWriter?

Just to be clear - I think your work on Analyzers is fantastic ! Really !
Seriously !
But it's a choice someone can make ... whereas index format is a given - you
have to live with it, or never upgrade Lucene.

But I think we've chewed that way too much. I am all for removing bw on
Analyzers, and 2396 is a great step towards it (or maybe it is IT?). Even
index format - I don't see when it will change next (but I think I have an
idea ...), so we can tackle it then.
