I am using list "Find an item" search. I have created the managed property and enabled "Search" and performed full crawl. The field type is single line of text.
I have value 555;666 and search with the whole text "555;666" is not working no matter what KQL operator or combination used.
Doesn't search work if there are any special characters in between two numbers and stored as text?

Some of the attempts
555;666 - no results
555\* - no results
\*666 - no results

This issue is on SharePoint 2013 on premises environment.
