A keyword search is a type of search that involves searching for specific words or phrases within a database. This means that when you perform a keyword search, you are essentially looking for instances where your specified keywords appear in the text being searched.
In other words, if you were to do a keyword search on "dog," it would bring up any instance of the word dog appearing anywhere in the document or website being searched. This type of search is commonly used by internet users when searching for information online and can be an effective way to quickly find relevant content based on specific terms.
