To add to my last followup posting, the only way I use oe_mathces(smiles) is in something like the following:
Select smiles,id from structure where oe_matches(smiles,'CCOC');
The match string 'CCOC' in this case, varies widely according to the needs of the user during that session. It is analogous to regexp matching, except that the semantics of oe_matches is nothing at all like string matching, even though smiles is actually a character string. Character string smiles are simply an extenral representation of a more complex c++ molecular structure object.
