> 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?
