Actually, it seems that both EasyFind and Spotlight are already making judgements, since the categories into which they subdivide pdf-type files are different. I agree with you that I don’t want either EasyFind or Spotlight, nor the encoders, making judgments. Rather, when I create and save a file, I’m the one that determines if the extension is acceptable. I would therefore like the files to be grouped according to their listed extensions, since these are what I have control over, and they’re what I can see myself when the file is listed.
Also, note that this doesn’t mean that pdf, PDF, and FDP all need to be merged into a single group, based on sharing a common extension. Rather, given that these all have the same .pdf extension, wouldn’t it at least make the most logical sense, and maximize usability, if these three groups were displayed contiguously when the search results are ordered by KIND? I.e., if EasyFind doesn’t want to merge pdf, PDF, and FDP files together, then wouldn’t it make the most sense to have these three groups of files – which, again, all have the same extension – appear one after the other when the ordering is by KIND, rather than having the three scattered well apart within the search results??
Indeed, should this not be a general principle when ordering by KIND, namely that if you have X different groups, all of which contain files with the same extension, that these groups should be listed contiguously? That way you maintain the separation you want, yet provide the logical grouping that I (and, I think, many people) intuitively desire?
Think about it – if someone is looking for a .pdf file, they really don’t care what the developer called it, they want a file that programs which read pdfs will recognize as such, which generally means files that end in .pdf. And what’s most easy, therefore, is if all these can be found together in the same spot – and easy is, of course, the raison d’être of EasyFind. If I’ve got a long list of results, I don’t want to have to manually scroll through all of them to find all the scattered groups that have .pdf extensions. That’s not easy – that’s me doing the work, instead of the program. And I don’t want to have to create more complicated searches in which I always include a search term that corresponds to the desired extension. Because that’s not easy either.
