WordDelimeterFilter and its Factory: access to charTypeTable

[Jerven Bolleman <je...@isb-sib.ch>]

Hi Solr Community,

I was wondering if it is possible to access and modify the charTypeTable
of the WordDelimeterFilter. 

The use case is that I do not want to split on a '*' char. Which the
filter currently does. If I could modify the charTypeTable I could
change the behaviour of the filter. Or am I barking up the wrong tree
and should I use a different approach?

Thanks,

Jerven Bolleman

I will have to do so anyway. As a test I used reflection to modify the
charTypeTable. And it works quite well, unfortunatly a different problem
that cropped up means that the WordDelimeterFilter as is is no longer
suitable for our use. So I will be writing a Filter from scratch. 

Thanks,

Jerven

I've found that creating a custom filter and filter factory isn't too
burdensome when the filter doesn't "quite" do what I need. You could
grab the source and create your own version.

FWIW: WordDelimeterFilter has a static package protected 
defaultWordDelimTable but there is no need to modify it -- you can 
pass your own charTypeTable directly to the WordDelimeterFilter 
constructor ... this might mean writing your own Factory, but you don't 
need to muck with the guts of WDF itself.
