"Non precious" filter is not working properly [opgelost]

Using advanced search with the following filters:
Country: Canada
Gregorian date: 2017
Metal: non precious
Your collection: both

Returns 19 coins including 10 gold coins.

I confirm, 10 gold coins (I get 24 total, though - maybe some of them were added in the last few days).

I never used that, will check.

Citeer: "January First-of-May"​I confirm, 10 gold coins (I get 24 total, though - maybe some of them were added in the last few days).

​I get 24 now as well. Guess some new ones were recently validated.

If I write "non precious" (with quotes), I get 82 coins.

I think the bug is that search every word. If I write non precious, I get items with non and precious, instead of nonSPACEprecious.

Citeer: "davidhs"​If I write "non precious" (with quotes), I get 82 coins.

​I think the bug is that search every word. If I write non precious, I get items with non and precious, instead of nonSPACEprecious.

​If you put quote around it I think it simply does not take this into account when filtering - try leaving it blank and you will get 82 coins as well.
The tooltip for the field contains quotes but just to indicate what the value should be.

I think your second statement is not accurate. If it searches for precious metals why silver coins are not on the list than?

If I enter gold in the metal field nothing is returned as well (for Canada 2017).

​It is true!
