I guess the link is unrelated. No idea why François posted it. :) But
I think what he is referring to is attributes that would have lots of
duplicates (like BEOS:TYPE).
But that is not a problem as long as it's not an attribute that's on
all files (like BEOS:TYPE). This is really an extreme case, and is not
really true for others.
Yep. I am aware of that. The problem is that users may not know that and
think that adding an extra attribute to all files (and one that would
have tons of duplicates) would be cool. :)
Like I said... why are there attributes on filetypes in general,
and a user may not want to search for it?

To display it in Tracker? I have a string attribute for images called
"Dimensions" which is basically the picture resolution (like
"640x480"). I don't index it but I do display it in Tracker on my pictures
folder. Other in the same category could include "Audio:bitrate", "MAIL:cc"
and so on.
While I'm guilty to have queried both of them, they don't really slow
down things a lot.
Yes, but I am always for not doing things that are not necessary. :)
Assuming that all attributes created for a filetype should be indexed
seems to me not to be a clean solution (it would be the easiest, that's
for sure). That said, I am all in favor of a more user-friendly way to
handle indexes.
But before we're taking sides, maybe we should get some data, and
actually create indices for all attributes in FileTypes, and then have
some benchmarks to see if its acceptable.
I am actually not taking any sides. I am just adding more data from my
own experience to the discussion. At least based on my usage pattern, I
would probably end up manually removing indexes I do not need or want
but it is not like this would be something I can not bear.
Note that file deletion is probably where you'll notice it the most,
since that's more or less the only action you do on many files and
assume it should be very fast :-)
Well copying files too. Even worse, moving files between 2 different
partitions. But yes, I understand your point. Again, the reason I am not
in favor of this change (in principle) is just because I think that
assuming the user wants all attributes created to be indexed is wrong.
