search:title="=xx" does not seem to work in EE7

[CreativePoweredGeek]

Description of the problem
When using the search parameter in an {exp:Channel:entries} tag, I expected it to be able to search the "title" field, what I got instead were inaccurate results.

How To Reproduce
Steps to reproduce the behavior:

1. Create a channel with a few fields.
2. in the title, use simple text like "AAS01, HE01, BP01, AS01" and then varying data in the other fields
3. Create a channel Entries tag like so: {exp:channel:entries channel="[channelname]" search:title="=HE01"}
4. See if the returned results are what you expect.

No Error Messages, just incorrect results

Environment Details:

• Version: [e.g. 7.1.2]
• PHP Version [e.g. 8.1.1]
• MySQL Version [e.g. 5.7]
• OS: [macOS]
• Web Server: [e.g. Apache on MAMP]

Possible Solution
I really don't know... it jus tseems to not be behaving correctly.
Additional context
Only other thing I can think now, is that I had changed the Title Label to “Customer Number” in the Channel setup, but I changed it back when I started having issues.
