The [loop-field title] causes the database to be called. It is a direct
query. In a normal search (not your search) you can access "In Memory"
variables by the tags:
[loop-param name_of_your_variable] or by [loop-pos 0] , [loop-pos 1],
[loop-pos 2] etc.

The "name_of_your_variable" and positions 0, 1, 2 refer to fields in the
search definition  given by "rf" or "mv_return_fields". It needs
something like:
rf=code,title
