Description

   Warning

   This function is EXPERIMENTAL. The behaviour of this function, the
   name of this function, and anything else documented about this
   function may change without notice in a future release of PHP. Use
   this function at your own risk.

   dbplus_find() will place a constraint on the given relation. Further
   calls to functions like dbplus_curr() or dbplus_next() will only
   return tuples matching the given constraints.

   Constraints are triplets of strings containing of a domain name, a
   comparison operator and a comparison value. The constraints parameter
   array may consist of a collection of string arrays, each of which
   contains a domain, an operator and a value, or of a single string
   array containing a multiple of three elements.

   The comparison operator may be one of the following strings: '==',
   '>', '>=', '<', '<=', '!=', '~' for a regular expression match and
   'BAND' or 'BOR' for bitwise operations.
