Subject [jira] Commented: (LUCENE-1166) A tokenfilter to decompose compound words
Date Thu, 24 Apr 2008 01:15:21 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12591895#action_12591895

Grant Ingersoll commented on LUCENE-1166:
-----------------------------------------

I pull the grammar files for the tests already. But I don't know if it makes sense to pull
them on build time because the end-user can easily download them. I need the XML versions
now - so the jar-file from Sourceforge does not help anymore (I have included the needed classes
from the FOP project - they use the ASF license as well).

I think they have to download automatically, otherwise the automated tests, etc. will not
run.  I applied the patch and ran "ant test" and it fails b/c I didn't download the files.

Also, much of the code has author tags that are not you, I am assuming you got it from FOP
per your comments above, but can you explicitly mark all the files as to there origin?

> A tokenfilter to decompose compound words you find in many germanic languages (like German,
Swedish, ...) into single tokens.
> An example: Donaudampfschiff would be decomposed to Donau, dampf, schiff so that you
can find the word even when you only enter "Schiff".
> I use the hyphenation code from the Apache XML project FOP (http://xmlgraphics.apache.org/fop/)
to do the first step of decomposition. Currently I use the FOP jars directly. I only use a
handful of classes from the FOP project.
> My question now:
> Would it be OK to copy this classes over to the Lucene project (renaming the packages
of course) or should I stick with the dependency to the FOP jars? The FOP code uses the ASF
V2 license as well.
> What do you think?
