Dear Paul,
I thought your problem interesting, so I have done the following experiment:
Running Windows 7 Ultimate 64-bit, I made sure Adobe’s 64-bit IFilter plugin was installed, and that the PDF filters were set for contents indexing (Indexing Options/Advanced Options).
Then, in Advanced Options, I selected Rebuild to rebuild the index from scratch (incidentally, I always create a directory C:\WindowsSearchIndex and relocate the index there, using the same dialog box).
Finally, I prepared three PDF files, “2007 Alpha paper.pdf”, “2007 Beta paper.pdf”, and “2007 Gamma paper.pdf”, which I put two levels deep inside “My Documents”.
Overnight, Windows completed indexing at 496,436 items, which I reckon is about right.
Today I started searching from the “My Documents” level.
1)
When I entered “2007”, Windows took around 35 seconds to find my three files plus all other files with “2007” indexed
in the content.
2)
I specified “2007 type:pdf”, and it took around 15s to find the three PDFs and all other PDFs containing “2007”.
3)
Specifying “2007 ext:.pdf”, it took 10s to find files as in (2).
4)
Then I specified ‘System.FileName:~<”2007” ’, and the three corresponding PDFs (only) were found within three seconds.
(The syntax means “find files with name starting…”).
You can find search syntax such as in (4) here:

5)
Finally, I used the 64-bit version of Agent Ransack (see my post just above) to look for “2007*.pdf”, from the “My Documents” level as above, and it found all three in 35s.
6)
Finally finally, I used the Advanced Search in Adobe Reader to look for “2007”.
This took a long time, because AR does a full un-indexed content search for the word specified.
The search appears to be of content only, and not of filenames, so it only found those of my prepared files which actually had “2007” in the text.
So all I can suggest to you is to try different search syntax (see reference above and my reference to a “Windows Search” document in my post above yours), and if that doesn’t work, try rebuilding your search index overnight.
Alternatively, use Agent Ransack, or (gulp) reinstall Windows to the stage that you have it how you basically want it, then make a system backup (use EaseUS, not Windows). I run a relatively fresh installation of W7U, which I refresh
from an external system backup if things seem to be going belly-up.
Of course, you may be running 32-bit Windows, which could for some obscure reason behave differently.
I am in the process of doing the same tests on a 32-bit machine, but for some reason it has been taking forever to index.
I have found a way of speeding up the indexing, and I’ll post when I have a result.
Incidentally, if you have the opportunity to put “tags” on your PDF files when creating them, that will also speed up using Windows Search to find them.
