Date search with ND parameter

Hello.
Perhaps there is a way to search by date with the ND parameter, but this is somehow not obvious.
Please, is it possible to search by date if the date on the page is indicated only by a period (for example, ND 1988-1988)?
For example, this page does not appear in search https://en.numista.com/catalogue/pieces63684.html

Thank you.

It is very useful idea!

It would be also great to see the coins with non-filed Type when searching among Standard circulation coin. Or to check them manually and add everything where it is missed.

I find it amazing that a person wrote the obverse lettering as "THE LAO PEOPLES'S DEMOCRATIC REPUBLIC" and the reverse lettering "WORLD FOOTBALL CHAMPIONSHIP . MEXICO 1986", and then the referee accepted it, when it clearly says "THE LAO PEOPLE'S DEMOCRATIC REPUBLIC" and "WORLD FOOTBALL CHAMPIONSHIP • MEXICO 86". Is it really that hard to read off the coin? I see errors like this too often.

Hello,
I'm not sure it fully answer your question, but you can find the 50 Kip World Cup coin by adjusting your query: use the search criteria "Gregorian date" instead of "Year".
https://en.numista.com/catalogue/index.php?mode=avance&p=1&l=laos&r=&e=laos&d=&ru=&i=&ca=3&no=&m=&v=&t=&a=&w=&dg=1988&f=&u=&g=&c=&tb=y&tc=y&tn=y&tp=y&tt=y&te=y&cat=y
"Year" represents the date written on the coin, and there is none for this coin.

and I forgot you can actually also search with "ND" in the field "Year".

So this would be the right way for this particular coin
https://en.numista.com/catalogue/index.php?mode=avance&p=1&l=laos&r=&e=laos&d=&ru=&i=&ca=3&no=&m=&v=&t=&a=ND&w=&dg=1988&f=&u=&g=&c=&tb=y&tc=y&tn=y&tp=y&tt=y&te=y&cat=y

But it doesn't solve the problem if I don't know what exactly is written on the coin.
Russian coins of the late 17th century do not have an exact date in the Gregorian calendar and do not lend themselves to such a simple search. Many members may not know about additional search options. I was just suggesting combining search terms for a user for a better result.

​Tnx...
It's all info from the past. I hope to clean it up some time.
Also Tnx for not reporting or adjusting it.

​Agree with you.
ND is nice, but if i search for all lao coins with 1988 I will miss coins.
Date is for most collectors the first thing to search for.
