Torsten Krah commented on LUCENE-5468:
--------------------------------------
Just for interest - are multiple dictionaries still supported with this change
(after reading all comments its not clear if it was dropped or not)?
This option is nice to have, because you can make local modifications and can
update the main dictionary from upstream (libreoffice etc.) without need for
merging or something.
If not - is there already a ticket to get this working again?

> Key: LUCENE-5468
> URL: https://issues.apache.org/jira/browse/LUCENE-5468
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 3.5
> Reporter: Maciej Lisiewski
> Priority: Minor
> Fix For: 4.8, 5.0

> Attachments: LUCENE-5468.patch, patch.txt

> Hunspell stemmer requires gigantic (for the task) amounts of memory to load
> dictionary/rules files.
> For example loading a 4.5 MB polish dictionary (with empty index!) will cause
> whole core to crash with various out of memory errors unless you set max heap
> size close to 2GB or more.
> By comparison Stempel using the same dictionary file works just fine with 1/8
> of that (and possibly lower values as well).
