Hello,

I have a field that I use for facetting.  I do not tokenize this field. It
has entries like:

AWB artikel 2, lid 1
AWB artikel 8:75
Algemene Wet Bestuursrecht artikel 8:75

Now, I don't want to get hundreds of facets, but I would rather like to have
a facet for each law, instead for each pragraph of the law. I tried to do
this with a SynonymFilterFactory using rules like

Algemene Wet Bestuursrecht artikel 8:75 => AWB
AWB artikel 2, lid 1 => AWB

But that doesn't work. And even if it would work, it would not be a good
solution, since I will never be able to come up with a complete list, as
long as I cannot use wildcards.

What would be the right solution for this?

I assume those are names of laws, followed by page/paragram numbers in
various formats? (and evidently "lid" is dutch for "section" ?)

i don't know enough about your source data to know all the posible
permutations you have to deal with, but i would tackle this with something
like...

 * KeywordTokenizerFactory
 * PatternReplaceFilterFactory
   - regex to strip off any \d+:\d+ at the end of tokens
 * PatternReplaceFilterFactory
   - regex to strip off any \d+,\s+lid\s+\d+ at the end of tokens
 * PatternReplaceFilterFactory
   - regex to strip off "\s+artikel" from the end of docs
 * TrimFilterFacotry
 * SynonymFilterFactory
   - mapping things lke "Algemene Wet Bestuursrecht" to "AWB"

-Hoss

Thanks,

this is exactly the type of solution  I need.
