: Hello Hoss! : The case here would be: "if total result set contains any original medicines : X, : then remove all generic medicines Y such that Y is a generic form of X." : : In your example and in my case, the result should be Vaxidrop + Generipill
then wunder's suggestion of grouping on the family, with a group.sort that puts the "originals" first, is the simplest idea i can think of OOTB. You'll still have to look at each group and "ingnore" the generics if the first item in the group is an "original" -- which of course means things like "numFound" won't really be accurate. An alternative solution using multiple requests wold simple be to do the query once with an "fq=type:original" filter, and if you get any results, then re-issue the query using all of the docids returned in some new "fq=-generic_of:(...)" filter to exclude any docs that are generics of hte matching originals. That logic could also be encapsulated i na custom component -- you could look at the "exclude" logic QueryElevationComponent for inspiration. the crux of the differnece between that while QEC gets it's excludes from a config file, you would get them from a (Query->DocSet)+FilterCache lookup -Hoss
