Searching the Web: operator assistance required ?
This study examines the effects of the search interface and Boolean logic training on user search performance and satisfaction. We compared the use of an assisted search tool to that of a simple search interface like those typically found at commercial search engine sites. We found that the assisted search tool had a significant positive effect on performance, satisfaction, and confidence. Promoting the use of advanced search features is therefore in the best interest of both Web search providers and users. In the absence of an assisted interface, a simple interface coupled with Boolean logic training was also an effective means for improving user performance. Given that most searchers choose to use the simple search box, it is important to provide them with applicable training to promote the effective use of the search tool. Interestingly, coupling the assisted interface with Boolean training was no more effective than either treatment alone.
