title: In SOLR, how to fq(filter query) for two different fields?
body: <p>I need the Filter Query to satisfy two different conditions on separate field.</p>
  
  <p>I tried the following and none worked</p>
  
  <p>fq="color:red AND type:book"</p>
  
  <p>fq="+color:red +type:book"</p>
  
  <p>I cannot use two different fq as thats the limitation set by the SOLRPHP lib I am using which requests $param["fq"] as a single argument. Therefore I need to pass one query to this function.</p>
  
  <p>I am new to Solr so please dont mind if I am missing something obvious.</p>
