Visual D: Search Window slowdown

[Nuno Leiria]

Hi,

Searching for symbols using the Search Window *always* takes 
around 5 seconds to start for every search. I've disabled 
Defender and am using an SSD so I'm surprised it's still so slow.

If this isn't easy to fix, could there be an option to only parse 
symbols from the current solution and remove phobos/runtime 
symbols? Searching for files is fast, so I imagine it's the large 
number of symbols without caching that causes the problem.
