Our “Result Sets” feature (c-treeDB layer) is a smarter and more convenient way to set filters. The “result set” handle is allocated for a specific table handle and it is then possible to add one or more criteria. Once the “result set” has all the criteria added, it can be turned on and off for any record handle that is allocated for the same table handle that already owns the result set. See the section titled c-treeDB C and C++.
