[jyuwono]

This is the master tracking item for launcher's search result weighting issues

Bug #	Title	PR #
#3271	Optimize the order of search results
#3229	Power Toys Run should remember frequently used apps
#3128	launcher isn't prioritizing exact match	#3213
#3169	An option to let running programs be first in the results list
#3145	Run takes too many launches to associate terms with launched apps
#3560	Prioritize results with a word that starts with my search term, not ones that end with it
#3559	Unexpected priority of search results for "term"	#3874
#3624	Support Fuzzy searching of apps
#3699	Allow filter out search results
#3461	if i search for cmd, cmd with no args should be first. all others should follow
#4229	The sort order of result appears unexpectedly

Based on the launcher spec, this should be added to settings:

[Dropdown] Set search result preference

• Most commonly used (default)
• Most recently used
• Alphabetical order
• Running processes/opened applications

I think we should prioritizing in the following order for open apps:

1. exact application name match (command prompt = command prompt)
2. exact file name and extension match (cmd.exe = cmd.exe)
3. exact file name match (cmd = cmd.exe)
4. sub matches (command = command prompt; prompt = command prompt)

It could also be helpful to simply search for a file called cmd* in the paths of the path variable and execute it, if the user type cmd and hit enter.
