Linked Columns - poor search function

Hi All,
Searching on linked columns is not great. seems to search left to right in a call and returns a broad range of results.

Image 1: searching on a partial “Name” and shows Monday not returning any results.
Image 2: serching the full Name, and shows Monday returning a variety of results with the accurate result required 3rd in the list!?

Is this a known bug and/or in the roadmap for improvement?
