Where to place ReversedWildcardFilterFactory in Chain

[Chantal Ackermann]

Hi all,

I would have two questions about the ReversedWildcardFilterFactory:
a) put it into both chains, index and query, or into index only?
b) where exactly in the/each chain do I have to put it? (Do I have to 
respect a certain order - as I have wordDelimiter and lowercase in 
there, as well.)

More Details:

I understand it is used to allow queries like "*sport".

My current configuration for the field I want to use it for contains 
this setup:

<fieldType name="text_cn" class="solr.TextField">
  <analyzer>
    <filter class="solr.WordDelimiterFilterFactory"
       splitOnCaseChange="1" splitOnNumerics="1"
       stemEnglishPossessive="1" generateWordParts="1"
       generateNumberParts="1" catenateAll="1"
       preserveOriginal="1" />
    <filter class="solr.LowerCaseFilterFactory" />
  </analyzer>
</fieldType>

The wiki page 
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters states for 
the ReversedWildcardFF:
"Add this filter to the index analyzer, but not the query analyzer."

However, the API for it says it provides functionality at index and 
query time (my understanding):
"When this factory is added to an analysis chain, it will be used both 
for filtering the tokens during indexing, and to determine the query 
processing of this field during search."

Any help is greatly appreciated.
Thanks!
Chantal
