@Wildcard Do you have Alfred's focus mode set to "Compatibility" in the Preferences > Appearance > Options > Focusing? If so, set this back to the default "Standard".

Is it indeed possible. Add your file filter and then go to the Advanced tab inside of it, and click the + to add a field. Add kMDItemTextContent.
 
That should get you going! Let me know if there's anything else I can help with.

I have Parallels installed right now and can actually test this so..
 
I opened Spotlight prefs, went to the Privacy tab. I popped open Alfred in File Browse mode by pressing ~. Alfred showed the contents of my Home folder, including the Applications folder, and Applications (Parallels). I dragged and dropped the Applications (Parallels) folder into the Spotlight Privacy area, then popped Alfred back up and typed 'reload' to reload the app  cache and all Parallels applications disappeared from the results.
 
Can you verify that these were the exact steps you took?

If you want to implement this feature on your own, deanishe, then you could just create a workflow that does it. You could just set it up so that you query everything using mdfind filtering for just the names. Then you could setup your own exclusion code.
 
Basically, just use the code that you wrote above as a packaged workflow for a more targeted search.

That seems to be it, much appreciated! 

The problem might be that recent versions of Alfred use a different focus mode.   Try changing the Focusing in Alfred Preferences > Appearance > Options to Compatibility Mode.    
That will make Alfred take focus the old-fashioned way.

great
One thing I would add is an optional message. Say:
timer 2m hey there! would Large Type "hey there!" instead of "2m"

Oddly enough, the feature you describe is in the PowerPack, but the feature I inferred from your topic title is not.
 
I thought you meant an easy way to search within a given folder, using Alfred.  I'm not talking about setting up a workflow to search a specific scope—I'm talking about a one-off thing.  Just navigating to a folder using Alfred and then choosing "search this folder using Alfred" from the file actions menu...but that file action doesn't exist.
 
I suppose it might be set up with a workflow, but I'm unclear how to do that, since it would require multiple inputs (first a folder for the file action, then a search term.)

This is great! (I also really like your LabelColor workflow.)
 
Is there a way to have the current filename pasted in and selected, ready to either tweak or overwrite? I find that when I rename files it's mostly to make small changes to long filenames so having this as a feature would be a big help.
 
Thanks again for the great workflow!

The way I use the calculator most often in Alfred is, I enter a partial calculation, hit enter, then toggle Alfred again, hit paste, and continue my calculation.  I was thinking this could be set up so that a right arrow (or a tab, or whatever shortcut) could change Alfred's currently entered text to the result of the current entry.
 
In other words, I enter "120-20" and press right arrow.  The text box then shows "100", and if I just type "/5" the text box will contain "100/5" and the subtext will show "20".  Whereas currently, if I enter "120-20/5", the subtext will (correctly) show 116.
 
Alternatively, and perhaps more usefully, a right arrow double tap at the end of the line could just enclose the currently entered expression in parentheses.  Then the sequence would be, "120-20" (right arrow) "/5", whereupon the display would show "(120-20)/5" with the subtext "20".
 
And while we're at it, if we could get the parser to recognize that parentheses directly next to a number means multiplication, that would be awesome.  That is: 53(20) = 1060.  Currently it only recognizes multiplication if an asterisk * is typed.  (Spotlight can parse this correctly...we can't have Spotlight outdoing Alfred!)  o_O

The most current version can now be found on GitHub with very special thanks to xilopaint for continuing and modernizing the original workflow.
GitHub Download. 
 
 
Below are my older versions which I will now leave AS-IS for reference:
 
DOWNLOAD (For Alfred 2)
 
DOWNLOAD (For Alfred 3)
 
For those that need to see/copy info from the system.
Just open Alfred and type "about"
 
To RESET the workflow type "xabout"
 
FN+ENTER will copy the selected entry to the clipboard.
SHIFT+ENTER will paste selected entry to front most app.
 
CTRL+ENTER will take you to Apple's support website (based on your hardware).
OPT+ENTER will take you to Apple's hardware specifications website (based on your hardware).

Updated the 'HardwareIcons.xml' to include all new hardware found/referenced for icons of machines. This brings the hardware list up to date as of macOS 10.13.2 (17C205)
This is just for Alfred 3 and the new filename is "AboutThisMac_2018.alfredworkflow", so make sure you are running the latest. This is a rather big update in terms of hardware icon support and I apologize for not doing it sooner folks!
 
September 26, 2017:
 
Added icon and updated script for macOS High Sierra.
 
February 1, 2017:
 
Added Macmini7,1 to xml for icon support.
 
August 15, 2016:
 
Added icon and updated script for macOS Sierra.
Made a new version for Alfred 3 removing older Operating Systems to fall in line with what Alfred 3 supports.
I am leaving the Alfred 2 version alone for those who still want to use it, but, it does not support macOS Sierra.
 
 
June 3, 2014:
 
Added Yosemite Icon (also updated script) for those using the Developer Previews so the System Version line shows the correct image.
 
July 23, 2013:
 
Added Mavericks Icon (also updated script) for those using the Developer Previews so the System Version line shows the correct image.

I found an error in a line of my workflow which on most systems is a lenient one, but on some results in the Human Readable Machine in line 1 of the results to simply not show up. The error also made the links to the support site and hardware specs site not function correctly. I have corrected this line in the workflow.
 
PLEASE NOTE: On SOME systems, and even on the current build of Mavericks, the plist file the workflow reads from is protected in a slightly different way. This means the permissions need to be changed on the plist. I have included the Terminal instructions in the 'readme' tab of the Workflow. To access this, load Alfred Preferences, Double Click on the Workflow in the left sidebar "About This Mac", and in the window that pops up, click the Readme tab ... and read!

Added Model Identifier beside system name in top row. SO for MY system it now shows "iMac 27-inch, Mid 2011 (iMac12,2)"
 
April 17, 2013 :
 
Fixed a couple minor issues with incorrect selectors in the script. Serial number should show now, and 'GB' after memory size will show again.
 
Added a system check for those that have multiple computers accessing one workflow folder (thanks DJay for pointing out that not everyone has only one computer).
 
Removed randomUID generator for items, as the latest version of Alfred2 makes it possible to NOT have to specify unique IDs. SO, if you want an ordered list, please update Alfred to 2.0.3+

+1
 
Agreed completely.  I would even go so far as a "Remember the last {#} of images copied" setting, totally separate from the text copying history.  So you could have it limited to five images, or whatever.  (Or, yes, just limit it to 5 MB or whatev.)
