I'd opt for both.  For example:

<search>
   <boolean-query>
     <required>
       <query-parser analyzer="...">"java based" -coffee</query-parser>
     <required>
       <term-query>
         <field>site</field>
         <text>apache.org</text>
       </term-query>
   </boolean-query>
   <range-filter>
     <field>date</field>
     <start>2004</start>
     <end>2006</end>
   </range-filter>
   <sort>
     <field>date</field>
   </sort>
</search>

This would be a natural thing to generate, e.g., from an "advanced 
search" page.

Doug
