Search engines make it easy to check facts online, but finding some specific kinds of information sometimes proves to be difficult. We studied the behavioral signals that suggest that a user is having trouble in a search task. First, we ran a lab study with 23 users to gain a preliminary understanding on how users' behavior changes when they struggle finding the information they're looking for. The observations were then tested with 179 participants who all completed an average of 22.3 tasks…

Why do users feel search task difficult?
TLDR
A coding scheme was developed based on the difficulty reasons users gave, which covered various aspects of task, user, and user-task interaction and helps understand search task difficulty, as well as provides a scheme for task difficulty control in experiment task design.
Is exploratory search different? A comparison of information search behavior for exploratory and lookup tasks
TLDR
The goal of this article is to investigate how to separate the 2 types of tasks in an IR system using easily measurable behaviors, and shows that IR systems can distinguish the 2 search categories in the course of a search session.
Exploration of dynamic query suggestions and dynamic search results for their effects on search behaviors
TLDR
The results showed that while the dynamic search results feature exposed the participants to more search results pages, shorter querying time and shorter queries, such a functionality did not change users’ general search process transition, as well as number of search sites, queries, and visited webpages.
How do users handle inconsistent information?: the effect of search expertise
TLDR
Investigating the effect of search expertise on search behavior and satisfaction criteria of users suggests that search non-experts tend to be less concerned about the consistency in their found answers, on the basis of which the design implications for making searchNon-Experts aware of the existence of inconsistent answers and helping them to search for supporting evidence for answers are discussed.
Is amount of effort a better predictor of search success than use of specific search tactics?
TLDR
Results indicate that the amount of effort is a good indicator of success in information seeking tasks and that high performers are more likely to use tools to help them organize and monitor their search results.
How do users grow up along with search engines?: a study of long-term users' behavior
With a stronger reliance on search engines in our daily life, a large number of studies have investigated user behavior characteristics in Web search. However, previous studies mainly focus on…
What Makes Re-finding Information Difficult? A Study of Email Re-finding
TLDR
A logistic regression model was developed to examine the relationships between variables and determine whether any factors were associated with perceived task difficulty and reveals strong relationships between difficulty and the time lapsed since a message was read, remembering when the sought-after email was sent.
Predicting Search Task Difficulty at Different Search Stages
TLDR
The results indicate that it is possible to make relatively accurate prediction of task difficulty at the first query round of a search, and can help search systems predict task difficulty which is necessary in personalizing support for the individual searcher.
Effects of task complexity on online search behavior of adolescents
TLDR
An increase in task complexity results in more search queries and used keywords, more time to formulate search queries, and more considered search results on the SERPs, which reveal that higher ranked search results were considered more often than lower ranked results.
Exploring and predicting search task difficulty
TLDR
The findings can help search systems predict task difficulty and adapt search results to users, and using only a limited number of significant variables (FC_FA) can obtain a prediction accuracy of 75%, with a precision of 88%.

The perfect search engine is not enough: a study of orienteering behavior in directed search
TLDR
A modified diary study is presented that investigated how people performed personally motivated searches in their email, in their files, and on the Web, finding that searching by taking small steps allowed users to specify less of their information need and provided a context in which to understand their results.
Investigating behavioral variability in web search
TLDR
A longitudinal log-based study that investigated variability in people's interaction behavior when engaged in search-related activities on the Web suggests that there are dramatic differences in variability in key aspects of the interaction within and between users, and between the search queries they submit.
Investigating the querying and browsing behavior of advanced search engine users
TLDR
The results show that there are marked differences in the queries, result clicks, post-query browsing, and search success of users the authors classify as advanced (based on their use of query operators), relative to those classified as non-advanced.
Web search behavior of Internet experts and newbies
Understanding the relationship between searchers' queries and information goals
TLDR
It is found that searchers are more likely to be successful when the frequencies of the query and destination URL are similar, and it is shown that the benefits obtained by search and navigation actions depend on the frequency of the information goal.
Understanding user goals in web search
TLDR
A framework for understanding the underlying goals of user searches is described and the experience in using the framework to manually classify queries from a web search engine is illustrated.
A cognitive study of information seeking processes in the WWW: the effects of searcher's knowledge and experience
  • Hitomi Saito, K. Miwa
  • Psychology
    Proceedings of the Second International Conference on Web Information Systems Engineering
  • 2001
TLDR
This work investigated, through a cognitive psychological experiment and its protocol analysis, human cognitive processes of seeking information on the WWW and the effects of a subject's knowledge and experience on the information seeking processes and performance and proposes a behavioral schema for tracing a subject’s searching processes.
Differences between novice and experienced users in searching information on the World Wide Web
TLDR
This study examined the effect of a user’s WWW experience on both phases of the search process and indicated that subjects with WWW-experience are more proficient in locating Web sites than are noviceWWW-users.
Eye-Tracking Reveals the Personal Styles for Search Result Evaluation
TLDR
The result evaluation style seems to evolve towards a more economic style as the users gain more experience, and the results suggested that economic evaluators were more experienced with computers than exhaustive evaluator.
Employing log metrics to evaluate search behaviour and success: case study BBC search engine
TLDR
It is argued that metrics can be generated from search transactional web logs that can help evaluate search engine effectiveness and this result is significant in that the identification of search outcome metrics will pave the way for assessing the effectiveness of site specific search engines and a greater understanding of the effectivenessof search engine functionality.
