It really isn't all that "complicated" as you just may be trying to "over think it" !
I did one search, specifically to get results, from this Database, as you will see, as I noted in an above post, about Dave, having posted in May 2015 with Thread titled , "We're Celebrating Iris'es This Week" for- "microbadges."
Then, performing a similar search *four years later*, posting those results here, so one may compare the same style search, again, to show how the "list" of results, have changed, since then... Simple.
Yet, decided that it would also be of even more interest, apart from the original search results of 'Iris genus " while factoring" in General " to be able to also compare results, such as by "Popularity", 'Relevance", "Tall Bearded", etc.. so that you may see the different results, if you use the Database capabilities,, here.
If you'd really wanted to "compare" it to "votes'" for "Favorite" Iris in the AIS, you most certainly can, if you'd be interested enough to do so.... I think someone even gave a link, posted in one Thread, to the AIS list results, for at least the year 2017... You'd just have to "search" for it here, that 's all. Simple enough to do, - "easy as pie."
