This popular feature of web search engines is thought to reduce physical and cognitive effort when formulating a query.<\/p>\n<p>Perhaps surprisingly, despite QAC being widely used, users\u2019 interactions with it are poorly understood. This paper begins to address this gap. We present the results of an in-depth user study of user interactions with QAC in web search. While study participants completed web search tasks, we recorded their interactions using eye-tracking and client-side logging. This allows us to provide a first look at how users interact with QAC. We specifically focus on the effects of QAC ranking, by controlling the quality of the ranking in a within-subject design.<\/p>\n<p>We identify a strong position bias that is consistent across ranking conditions. Due to this strong position bias, ranking quality affects QAC usage. We also find an effect on task completion, in particular on the number of result pages visited. We show how these effects can be explained by a combination of searchers\u2019 behavior patterns, namely <em>monitoring<\/em> or <em>ignoring<\/em> QAC, and <em>searching<\/em> for spelling support or complete queries to express a search intent. We conclude the paper with a discussion of the important implications of our findings for QAC evaluation.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n<p><a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" href=\"https:\/\/1drv.ms\/v\/s!AOHhoN0FukEfrlA\">Eye-tracking video<span class=\"sr-only\"> (opens in new tab)<\/span><\/a> &#8211; this link takes you to the recording of one task performed during our experiment, with overlayed eye-tracking data (fixations and saccades).
