Understanding how Search Interfaces Shape Behavior

Dr. Diane Kelly, University of North Carolina, Chapel Hill, USA

It has been well documented that when people search for information online they typically submit short queries and only view a small number of search results.  It is generally accepted that this is the ‘natural,’ ‘optimal’ and ‘easiest’ way for people to search and that, in general, faster is better.  In this talk, I explore the idea that contemporary search interfaces have conditioned people to engage in these types of search strategies and that these strategies might not always lead to the best results. I will present results from a recent study that compared three search interfaces that varied according to the amount of cost required to query, where cost was operationalized as time. Our results show that people who used the interface that was the most costly to query submitted fewer queries, spent more time generating their initial queries and viewing search results pages, examined more documents per query, and went to greater depths in the search results list. These people were also more successful and less frustrated: they saved more relevant documents, reported lower mental and temporal demands, rated their queries as more successful and reported less frustration than people who used a standard search interface. Our results suggest that query facilities that are designed to encourage people to slow down and submit a small number of well-planned queries can potentially lead them to engage in search behaviors that are associated with less mental and temporal demands and better performance.
