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.
