Possibility that search engine takes users' metadata into account

When we upload a feedback that our client give to us, we want to attach all the users related to the same account, but when I add manually a upvoter, I can online search by user, if I write our metadata variable “uid” it’s not appearing all the ussers attached to that metadata varaible

Is there anny possibility If i search by a metadata variable, that all the ussers related with that metadata variable appear?

It would be very important to us

Thanks
