Many search queries entered in the RoyaltyStat search form contain only one keyword or a short phrase such as injection, inject*, mold*, form*, utility*, wireless equipment. One keyword or one phrase search queries are combined with the use of simple operators AND, OR, AND NOT to join the initial keywords. E.g. inject* OR mold* OR form* in a single query. Initially, users enter a prototypical word of a category or, simply, a word or phrase they know. They don’t develop their search strategies further and don't appear to use our search guide. This behavior is known as a paradox of the active user.
