It may be possible to define either different relationships or some filtered portals to get what you want, but can't tell for sure without knowing in detail what the criteria are for these "finds".
Count, used in conjunction with a relationship that only matches the current record to records meeting your "find" criteria is one possibility.
Defining a "count of" summary field in the related table, and then setting a portal filter to limit the related records to only those that meet the criteria is another option if you are using FileMaker 11.
And with either approach, a separate "report table" where each record can specify different criteria for either the relationship, portal filter, or both can allow you to combine counts for different and even overlapping groups of records in the same report.
If the different "found sets" do not overlap, you may also be able to simply set up a summary report with sub totals (such as your counts) for each sub group of the total set of found records. (And this report need not list each individual record, just the group sub totals.)
Thanks Phil. Your help on this forum is golden. The "count of" and "total of" fields in conjunction with filtered portals did the trick.
