Uwe Schindler commented on LUCENE-2548:
---------------------------------------
I think the discussion about Term removal is not really related to this issue.
Removing Term would only have the big advantage that we don't suddenly change
Term to no longer intern() the field name and so maybe code outside Lucene
using Terms and relying on the fact that the term field name is interned, may
break. Removal of intern() must then be clearly noted in migration.
> Remove all interning of field names from flex API

> Key: LUCENE-2548
> URL: https://issues.apache.org/jira/browse/LUCENE-2548
> Project: Lucene - Java
> Issue Type: Improvement
> Reporter: Uwe Schindler
> Fix For: 4.0
>
>
> In previous versions of Lucene, interning of fields was important to minimize
> string comparison cost when iterating TermEnums, to detect changes in field
> name. As we separated field names from terms in flex, no query compares field
> names anymore, so the whole performance problematic interning can be removed.
> I will start with doing this, but we need to carefully review some places
> e.g. in preflex codec.
> Maybe before this issue we should remove the Term class completely. :-)
