Subject [jira] [Created] (SOLR-2968) Hunspell very high memory use when loading dictionary
Date Wed, 14 Dec 2011 02:52:30 GMT
Hunspell very high memory use when loading dictionary
-----------------------------------------------------

                 Key: SOLR-2968
                 URL: https://issues.apache.org/jira/browse/SOLR-2968
             Project: Solr
          Issue Type: Bug
    Affects Versions: 3.5
            Reporter: Maciej Lisiewski
            Priority: Minor


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).
