Actually... I would say "no". I'm assuming by "everywhere" you just mean binary-search, and it's often quite handy to search for phrases embedded within DLL's so you can figure out the precise file that's giving you grief. I'll grant you that's an unusual circumstance and wouldn't regularly apply to most office-workers, housewives, and former world-champion parkour exhibitionists, but in any "professional" programme I use (such as comparison-utilities, or really
anything that can read files) when I tick the "contents" option, I always assume it will at the very least "fall back" on binary search if all else fails.
I don't think that expectation is entirely unfounded. Yes, most people will think to rely on the usual text-approach when doing searches - but exactly how many of them have ever even heard of iFilters let alone know how to find them or what to do if their associations break?
For example, just playing around with that SearchFiltersView thingy, I discovered I have filters I've never even heard of and certainly did not install wittingly (Visual Studio is a bloated back-stabbing thing these days). Obviously, such things are harmless, but if a scatologically forensic bottom-feeder like myself wasn't aware they were installed, how can you expect regular punters to think: "I know, I must need one of those iPhone thingies for this!"?
Especially in sanferno's case it's doubly confusing when his text search works fine in x2 but fails in a dedicated search programme. I too would begin to wonder why my wedding dress no longer fits like it used to.
That said, it's curious that if someone has programmes installed that can handle "Adobe InDesign documents" in the first place, it's a wonder such filters aren't installed by default. But then again, Adobe are the company that took roughly 5 years to understand how to properly code for x64 systems, so they are at the low-end of "quality" stuff anyway.
But back on the original point... you do have to realise that these days everyone
automatically assumes for example that something can search within all types of archives "out of the box". And why wouldn't they? Granted, searching within proprietary file-formats is not to be expected, but everything just short of that would be.
"But wait - you mean I
can't search by content within RAR files? Why not? Programme <x> does it out of the box... it says so on their website".
So... um... no, "the mature stance" is the one that can catch everything no matter what it is (within reason). Binary included, archives (not just ZIPs!), etc. Everything.
