Google Spread Sheet Search any part of the cell and display

Hi Team,

I have a code to search and display the exact field in any column.

I would like to get the code of partial search, such that the input value if we entre is partial, should display all the possible fields.

Eg. Search "Evaluation" in the search field should display all the possible results.
