title: Could somebody explain SOLR requestHandlers and responseWriters in detail?
body: <p>Firstly, many parts of the solr wiki is not very useful for somebody who just learned how to index and search fields. It seems it is written for experts! It uses terms that is RELATIVE to solr, so it's very difficult to understand it without reading it several times over.</p>
  
  <p><strong>NOTE</strong>: I have a classifieds website where the most recent ads always shows up first, so sorting is not relevant for me, except for sorting on price and date no other options are available for the users, and also how many results per page.</p>
  
  <p>I know a <code>requestHandler</code> is a way to "do some stuff to the query" right?
  But how to know which handler to use is hard for me. And how to configure one also.
  All I know is the handler is specified in the query-string like "<code>qt=my_handler</code>".</p>
  
  <p>Also, the same questions apply to <code>responseWriters</code>, which to use? How to configure?</p>
  
  <p>What else should I know about these handlers?</p>
  
  <p>How is a good and effective way to use them?</p>
  
  <p>I really should write something up about getting solr implemented into a PHP website after I learned all these things.</p>
  
  <p>Thanks for all your help!</p>
