Here's an issue that I am facing.
The table that contains the query substructures has some other important columns.
When any of the structures in this query table match a structure in a 2nd table, I need the other important columns in the query table to be retained.
Since no column, not even the original query is retained in a substructure match node result, one has to go thru r-group and other nodes to get the original substructures and corresponding columns back. In many cases the nomenclature of r-groups and attachment points makes retrieving this very difficult. In my case the queries were input from a column of the matched pair nodes from erl wood.
In line with suggestions earlier, it would indeed be very useful that whenever a match is found the query table info is also retained along with the hit table info. There could be a choice box prompting the user for the same. At the very least the original structure query.
