Jan, I'm attempting, to determine it's "relevance'", just by the very nature of the results, given, when displayed, by the system, as being a "Relevance' result of the search, by the search of Iris using ; Iris genus' by relevance", just as you may search, "Popularity" of all the Iris genus, or if I had chosen, to do so, by, only searching "tall bearded" only, for example...Which would have been "different" than the original search method.
But, just to simplify it, keep it at genus Iris, while doing those "Searches", just like dave had probably done , in 2015, to repeat the same search...Of course, 'omitting" the first category , being, that is Iris in general that are 'uncategorized", whatsoever, at all...(simply, not being "relevant' or "popular' as a cultivar.)
As, I would assume, dave also used that very same search, of "Popularity" given, not only the "comment", yet the very nature of the results, it had included. But, I can certainly search "tall bearded" & compare that result, also, just as I did, with the above searches & see if it varies much, from those other searches, by much at all, also.
As I've listed both results, already, on paper.. of the first page, results, of each category & could very well just as easily do the same, with "tall bearded" if you;d like me to list, all the results given, for "tall bearded".
Would you care to see, if there is much difference ? I'm fairly certain "Cat's Eye', will no longer be included & only slightly change that search result.....
