Configuration > Search>Relavance>Modification events

Hi, all.

I have a little bit of a Strange question can't really find info on it in the training material.

It's a two-parter.

Configuration > Search>Relavance>Modification events

A) What would the values have to be if I am heavily reliant on searching within a metadata card to link a property, that property would have had a recent modification and I would like it to appear within the "Top 50" drop-down selectable values when linking it into the metadata card.

B)

Just as an example, I say I have 100,000 class values and I can only search by name or scroll down to the top 50 most relevant or recently modified properties, how would I get that logic to work?

Kind Regards
