Windows 10: Windows Search response speed - partially indexed drive vs fully

Hi, I see a huge difference in how fast it takes for an indexed item to be found on a drive between the drive being fully indexed, and selectively indexed.

if I index a couple of folders on, say, drive H:, then use search in file explorer to find something indexed with H: open in file explorer, it takes a relative age for an indexed item to be found. Green progress bar creeps across..

If, however, I have all of H: indexed, finding said item is very very quick.

Now logical me would expect the search to first scan indexed items, then the rest of the drive/partition. But the green progress bar in the partially indexed case suggests that the reverse is true.

Any thoughts? Thanks!

(P.S. I normally use a 3rd party tool to find things- so much more convenient and faster, which explains why I haven't bothered thinking about this much before).

Related: I suspect Cortana's message 'These results may be incomplete' when doing a documents search reflects the above. Now I have H: fully indexed, Cortana can find text content there instantly, whereas on E: where have two folders indexed, I get that message- equivalent, I guess, to the green progress bar.

Search Option not working on Brand New Surface Book

Brand new Surface Book fully patched with Windows 10 Anniv. Update and the Search Bar is only partially working.

If I search for Settings, it shows up, but if I search for Mouse, or update, or any other items they don't show up. Oddly enough it does seem to be searching the Windows Store as Apps show up. (that I haven't installed.) My Profile is fully indexed. Tried
stopping and starting the search service. There is a few post online about deleting registry keys and or creating folders, but not sure why I need to do this on a brand new system.

 

WIN10 search not returning results from indexed drive

Greetings

Windows 10 taskbar (Cortana) search is not returning results from an indexed drive. Both the C and D drives are indexed (specific Locations) and task bar search returns results from everywhere but the D drive. However, if I search via file manager search
returns all the results.

I have tried

• rebuilding the index
• stating and stopping the service
• running the troubleshooter (find a permissions problem)

The machine is fully patched with the latest release.

Any assistance would be greatly appreciated.
