Dynamically deriving the param value in solrconfig requestHandler

[Senthilnathan Vijayaraja]

hi,

 Is there any possibility to derive a value to a param from other params
like below,

<requestHandler name="/main"
class="com.solr.custom.handler.MySearchHandler">
  <arr name="components">
   <str>query</str>
   <str>debug</str>
  </arr>
  <lst name="defaults">
   <str name="size_relaxed">*size:['$minSize' TO '$maxSize'] *</str>
//minSize and maxSize will be supplied as query parameter or else
defaults
to below values((i.e size_relaxed=size:[0 TO 100000000] ))

*<str name="minSize">0</str>      <str name="maxSize">100000000</str>*
  </lst>
 </requestHandler>


Thanks & Regards,
