Places: Support sub-km distances when searching for locations

[loulou91]

Present geographical search is a nice feature and works well but precision is today 1 km which may be sometimes too rough.
I tried to enter dist:0.1 but I got an error ("unable to do that").
I think dist unit is integer...
Could it be possible to increase precision using float in place of integer or to change unit km to meter?

Thanks in advance.

It's an approximation due to how the query works (for maximum compatibility with all databases). Accepting a floating point number instead of an integer should still be possible to implement with reasonable effort.

@loulou91 I've started a new preview build so you can test these changes, it should be available within the next hour:

• https://docs.photoprism.app/getting-started/updates/#development-preview
• https://docs.photoprism.app/release-notes/#development-preview

Note that our public demo at https://demo.photoprism.app/ will be updated as well if you don't want to use our preview build to test with your own pictures.
