Problem with "in use in" search field? [Risolto]

I want to know all coins in use in Russia during 1914, so:

When I go to Russia, type 1914 at “in use in” field, to list all coins in use at Russian in 1914, I get 1 result back:
https://en.numista.com/catalogue/index.php?e=russia&r=&ct=coin&im1=&im2=&tb=y&tc=y&tn=y&tt=y&tp=y&cat=y&ru=&ca=3&no=&v=&i=&b=&ie=&u=1914&a=&dg=&m=&f=&t=&w=&mt=&g=&se=&d=&c=&wi=&sw=

If I put 1914 in gregorian year, all coins minted in 1941, I get 11 results. And those results doesn't includes that previous one as tha coins wasin use in 1914, but not minted in 1914.

https://en.numista.com/catalogue/index.php?e=russia&r=&ct=coin&im1=&im2=&tb=y&tc=y&tn=y&tt=y&tp=y&cat=y&ru=&ca=3&no=&v=&i=&b=&ie=&u=&a=&dg=1914&m=&f=&t=&w=&mt=&g=&se=&d=&c=&wi=&sw=
 

So, am I doing something wrong here?

Thanks.

If there is no demonetisation date this search will give you nothing. So other then the one coin with a demonetisation date of 1917 there seem to be no catalog pages with enough information.

Ah, so that's the range that it search at.

I don't think so. It includes all coins that are not demonetized.  US example  with every US coin ever made.

Non of them are demonetised, all of the Russian ones are, hence Numista would need to know when they were demonetised to give a a list for a specific year.

Ah..I get it now. Mistook “no demonetisation date” for “not demonetized.” 

Hello,

Idolenz gave the correct explanation.

I adjusted the search engine so that, even when the demonetization date is unknown, coins minted during the searched year are still returned.
