[Plugin: wp-autosuggest] How to remove post content of search and select categories

Hello, okay? I loved the plugin, excellent! I have questions:
How can I remove the post content of the search, leaving only the post title? Also, how I can determine the categories of the search? Because I want to appear in the suggested search only categories that I set.

Thanks!!!
