Subject [jira] [Updated] (SOLR-4452) Hunspell stemmer should not merge duplicate dictionary entries
Date Wed, 03 Jul 2013 02:11:20 GMT


Jan Høydahl updated SOLR-4452:

    Attachment: SOLR-4452-caseinsensitivemerge.patch

This extra patch takes care of this corner case where two lines are same word but different

For case sensitive dictionary we will treat these as two distinct words. But for case insensitive
dictionaries we'll merge them as before.

Sounds good? Or would it be better to treat these also as duplicates and use only the last
one? If so, we should modify the unit test instead.

> Each word is listed once with is base form, and the flags after the / define allowed
prefixes and suffixes.
> In HunspellDictionary's parsing logic, if the same base word should appear multiple times
in the file, the flags from the duplicate entry are added to the flags from the existing entry.
> However, HunSpellStemFilterFactory allows for a comma-separated list of dictionary files
to be passed in, the idea being that you can have your own custom extensions and not need
to modify the "standard" ones which may change upstream once in a while. This feature now
works only for NEW words, not for overriding existing entries from the first dictionary.
> Would like to change this behavior, so that the last line read overwrites any previous
one. This will both fix the custom dictionary issue and also fix unintentional wrong original
dictionaries, where someone added a word definition at the end without realizing there was
another already.
> For the en_UK.dic there are no duplicates. For en_US.dic there is one duplicate, so I
argue this behavior is a bug and not a feature dictionary authors depend upon.
