re: Is there a paid extension to implement a search function?
Sorry, no, there is not… well, if you have no need for pagination you could use the search widget that comes with the Widget Pack. But, if you have a larger directory which needs search, you likely need pagination.
re: Do not want to change the layout / look of the Default Entry Card 3.0 template that I am currently using as it fits my needs 100%, so would not want to change template. Unless template can be made to look like Default Entry Card 3.0 ?
My suggestion is to use the cMap template. You can use the Template Customizer on it to make (style) it visually similar to the Default Entry Card template but the layout will have differences.
I hope this answers your question thoroughly!
