+ * local parameters. This is useful in specifying defaults in configuration and
+ * letting clients indirectly reference them.
+ * Example: <!query defType=func v=$q1>
+ * if the q1 parameter is price then the query would be a function query on the price field.
+ * if the q1 parameter is <!lucene>inStock:true then a term query is
+ * created from the lucene syntax string that matches documents with inStock=true.
