Subject [jira] [Commented] (LUCENE-3883) Analysis for Irish
Date Tue, 20 Mar 2012 04:13:43 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13233183#comment-13233183

Robert Muir commented on LUCENE-3883:
-------------------------------------

To make matters worse: this exact example of splitting on hyphen for this Irish case is 
actually mentioned on http://en.wikipedia.org/wiki/Hyphen#In_computing

>From there it seems like the right thing to do is heuristically convert to 
U+2011 (non-breaking hyphen) but this only affects Unicode line-break rules,
not word break rules :(

So it seems like the least hackish workaround would be for a charfilter to 
convert n-athair -> nAthair (to prevent the tokenizer from splitting it up),
since the IrishLowerCaseFilter will convert it back and stem it anyway.

I'll see if i can hack something up.

says it will be added during the week.
