Michael McCandless commented on LUCENE-3069:
--------------------------------------------
Note that all the commit messages at the end of this issue (generated by Jira's
FishEye plugin I think) incorrectly state that "Han Lee" committed changes here.
This is due to an issue in FishEye with username collision ... Han Jiang's (who
really committed here) apache username is "han", but in Jira that user name
belongs to Han Lee, which leads to this mis-labeling.
Here's the INFRA issue: https://issues.apache.org/jira/browse/INFRA-3243 but
it's currently WONTFIX unfortunately ...
> Lucene should have an entirely memory resident term dictionary

> FST based TermDictionary has been a great improvement yet it still uses a
> delta codec file for scanning to terms. Some environments have enough memory
> available to keep the entire FST based term dict in memory. We should add a
> TermDictionary implementation that encodes all needed information for each
> term into the FST (custom fst.Output) and builds a FST from the entire term
> not just the delta.
