Changing analyzer in an indexwriter
Hi,
I'm upgrading to lucene 5.1.0 from lucene 4.
In our index we have documents in different languages which are analyzed
with the correct analyzer.
We used the method addDocument of IndexWriter giving the correct analyzer
for every different document.
Now I see that I can define the analyzer used by the IndexWriter only in
the creation and I cannot switch analyzer on the same IndexWriter.
We allow to do some searches cross languages, so we cannot separate the
documents in diferrent indexes.
Suggestions for the better way to solve this use case?
Thank you,
Lisa

Thanks, I'll fix MIGRATE.txt to mention this.

Thank you everyone! Could I suggest that this change should be mentioned in
the migration guide? In our case it requires a complete reindex and code
change (in search too) so maybe others are in the same situation.
Thank you again for the prompt help,
Lisa

See the discussion on
https://issues.apache.org/jira/browse/LUCENE-6212 about this? It's
best to isolate different languages into different fields...
