Weird Harold always has the answers.
Unless the OP wanted to look for a user number range from 1234 to 2980.
Finding one by changing 'xxxxx" to "yiyyyyyy" could take years if you do not know the number, name or range for the poster you remember.
Remember, we're dealing with queersetti - an aging man who probably is only able to remember pieces and parts of various things in his past. To him, they're immediate and current, but he can't put the faces with the names.

And we need to be able to search for Posts between "mmm,ddd,yyyy" and MMM, DDD, YYYY".
And I need a chicken salad sandwich, some tea, and a cookie if you please.
And a foot massage.
that's all.
for now.
