Product terms - Select in which product terms or attributes the plugin will look.
Product terms cache - If enabled, option allows caching of taxonomy terms for easy access. If you don't add much attributes, tags or categories use this option to improve performance. Adding tags and other taxnomy terms will require this cache to be reset by saving the options, so if you do this more ofter you're better with dynamic terms and leave the cache off.

Product SKU compare - SKU compare can be exact or like, use which one you prefer.
Product meta - If you need more meta keys to search in, like custom fields, use this manager. Add meta keys and set how to compare the value with the search query.
