Coins search - strange behavior

Hi,

Seems to me there is a bug in search mechanism. I tried to search 5 rupees Indian coin for year 2009 (see screenshot), all other filters, like coin type, etc. set to "all".


In result I get only 3 coins. But where all other coins? For example that one: https://en.numista.com/catalogue/pieces12050.html

Is it a bug or I'm doing something wrong?

It does seem to be a bug. The ones not shown are ND(2009). If you use the Gregorian date it returns all.

I wouldn't call it a bug it is how Numista always behaved at least since I used it.
ND simply have no date or real date so you will have to use Gregorian year. With the new possibility to keep the wrong date for NDs it is also not easy to change that behaviour, I guess.

Hello,
This is the expected behaviour. The filter "Year" matches with the year as written on the coin. To find the coin in example, which is non-dated, you can either search for "Year: ND" or "Gregorian date: 2009".
