If you know the item id you can use SQL to find the search name.
First you run the following against the ca database:
select * from tblintdiscovereditems
where discovereditemid = *
then using the search id from the results of the above query you run the following:
Select * from tblIntSearches where searchid = * (found in the previous query)
that will let you know what search it is from.
