The records addition makes the searchsitem available as a list of records with fields. It may be iterated with a dtml-in. In this case that would be <dtml-in searchitem>. The sequence-item then has the 'fields' of the record as its attributes, so that in this case you can access them with <dtml-var connector> and <dtml-var searchterm>. This works nicely in a normal DTML Method.
The problem seems to be that the SQL Method is only able to retrieve items from the REQUEST.form dictionary, and the records list is in the REQUEST object itself. This seems not to be directly accessibly from the SQL Method, because it gets its values from the stated input fields (the ones you define as tokens in a SQL Method). But I'm not completely sure.
OK, forget about this. I was completely off track. Somehow on of the methods on the way apparently got messed up. The proposed way of including a search worked as I had intended and in exactly that way. Sorry to have posted misleading messages. Please ignore them Rik
