Filter to cut out all zeors?
Hey there,
I'm trying to figure out the best way to cut out all zeros of an input string like "01.10." or "022.300"...
Is there such a filter in Solr or anything similar that I can adapt to do the task?
Thanks for any help

won't this replace *all* 0s ? ie, 1024 will become 124 ?

With solr.MappingCharFilterFactory[1] you can replace all zeros with "" before tokenizer.
<charFilter class="solr.MappingCharFilterFactory" mapping="mapping.txt"/>
SolrHome/conf/mapping.txt file will contain this line:
"0" => ""
So that "01.10." will become "1.1." and "022.300" will become "22.3" Is that you want?

With solr.MappingCharFilterFactory[1] you can replace all zeros with "" before tokenizer.
<charFilter class="solr.MappingCharFilterFactory" mapping="mapping.txt"/>
SolrHome/conf/mapping.txt file will contain this line:
"0" => ""
So that "01.10." will become "1.1." and "022.300" will become "22.3" Is that you want?
