Search for companies using keywords. The AND keywords field is for keywords that all must appear on the company website. The OR keywords field selects a subset of companies that contain at least one of the OR keywords.

The logic is as follows:

(andkeyword1 AND andkeyword2 AND andkeyword3) AND (orkeyword1 OR orkeyword2 OR orkeyword3)

For example:

(defence AND missiles AND manufacture) AND (hypersonic OR drones OR unmanned)
