Subject Sharing common config between different search handlers

Hey there list,

my application needs two searching modes. The first modes needs to
consider synonyms the other one must not.

Currently I have two field types with basically the same configuration
except that one field type uses a SynonymFilter the other one doesn't.
Furthermore there two Searchhandlers. The first one uses only fields
that recognises synonyms the other one uses only fields that doesn't
recognise synonyms.
So far, so good.

But I would like those two Searchhandlers to share the rest of their
configuration. Because if anything needs to be changed, it need to be
done for both Searchhandlers. I think that's kind of ugly.
Additionally I would like the client (the web page the triggers a
search) not to know anything about the field names. Therefore I do not
simply specify a list of query fields in the request.

To clarify my situation, follows a sample solrconfig.xml (I left out
many of the details to save time and space, but I guess you get the idea).

<requestHandler name="/search_with_synonyms" class="solr.SearchHandler">
  <lst name="defaults">
    <str name="defType">edismax</str>
    <str name="rows">10</str>
    <str name="fl">id, score</str>
    <str name="qf">description_with_synonyms</str>
    <!-- a lot of other configuration happens here -->
  </lst>
</requestHandler>

<requestHandler name="/search_without_synonyms"
class="solr.SearchHandler">
  <lst name="defaults">
    <str name="defType">edismax</str>
    <str name="rows">10</str>
    <str name="fl">id, score</str>
    <str name="qf">description_without_synonyms</str>
    <!-- a lot of other configuration happens here -->
  </lst>
</requestHandler>

I thought about using only SearchHandler and a filterquery to get rid
of the "synonym-results" if they are not needed. But I as far as I can
tell, that's not possible.

Thanks in advance and any idea is welcome,

Jochen
