List item search not working properly for Managed Metadata field

Question

In list webpart, when we are searching for a Managed Metadata field value with its managed property, it is not working as expected for certain values. Partial match is working fine.

This is how we are searching:

<Managed Property>: <Managed Metadata value>

Below partial match is working:

<Managed Property>: <Managed Metadata value partial match>

Kindly advise.
