Advanced Search Criterion


I try to use this criterion to find all fields used in SQL statements, but it does not work very well for me.

here are the results

as you can see the field named "sql-salidaendpoint" and used in a SELECT is in the results

but the other filed named "sql-num-dias" which is also used in another SELECT is not in the results

Why the fileds "sql-num-dias" does not appears in the results?
