“…However, very few studies have explicitly considered the user's cognitive aspects of search interactions with suggested search terms for refining queries (cf. Liu & Belkin, 2008;Liu & Wacholder, 2017;Niu & Kelly, 2014). As indicated in a study of user modelling, the implicit feedback from clicks and query reformulations in Web search (Joachims et al, 2007), it is important to obtain detailed evidence of the user's query reformulation decisionmaking process from user search behaviours, such as search terms, time spent, clicks and eye tracking data, because user search behaviour data can be used to improve overall search experiences.…”

“…For instance, it was found that there is no relationship between clinical knowledge and search effectiveness in medical students' MEDLINE online searches (Pao et al, 1993). It was found that domain experts can perform significantly better than search experts when MeSH terms are available in the search interface (Liu & Wacholder, 2017). While ordinary searchers may be satisfied with the search results from short queries, effective search in specialised domains requires the domain knowledge and ability to formulate complex queries (Leroy et al, 2007).…”

“…From a research perspective, however, the usefulness of these techniques for search user interface design in support of query reformulation has rarely been evaluated in interactive search environments (Hearst, 2009(Hearst, , 2011Wilson, 2011). User studies have suggested that domain experts benefit the most from MeSH (Hersh, Haynes, & McKibbon, 1994;Liu & Wacholder, 2017) but that they also need search tools to support their formulation and reformulation of queries (Lykke, Price, & Delcambre, 2012;McKibbon & Fridsma, 2006). The design of a single search box in modern search systems presumes that users have very specific questions when they look for information.…”

Controlled vocabularies such as Medical Subject Headings (MeSH) have been extensively used to organise information resources in the biomedical domain. However, the usefulness of these terms for information access has not been rigorously evaluated in interactive search environments. The objective of this study was to gain an understanding of domain experts' interactions with novel search interfaces within the context of biomedical information search, with a goal of better interface design of information retrieval systems. An eye tracking study of biomedical domain experts' interactions with novel search interfaces was conducted, considering user's individual differences and gaze behaviour. The findings suggest that types of search interfaces have significant effects on gaze behaviour in terms of fixation-based measures of areas of interest, i.e. visual attention to the elements of title, author, abstract and MeSH terms in document surrogates. Significant interaction effects between cognitive style and user interaction with search interfaces were found, specifically the amount of attention to MeSH terms by analytic and wholistic searchers. These findings contribute to our understanding of the relationship between cognitive styles and gaze patterns in information search. Based on these findings, the implications of individual differences and gaze behaviour for search interface design are discussed.

“…Professional search tasks are also characterized by the application of domain 130 expertise. Liu & Wacholder, (2017) highlight the key role of domain expertise in adequately exploiting controlled indexing vocabularies such as MeSH. Similarly, Tamine & Chouquet (2017) demonstrate the role that domain expertise plays, not only in the lexical representation of information needs, but also in the perception of relevance.…”

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large 15 domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal 20 researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental 25 needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and 30 recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The * Email address: tgr@uxlabs.co.uk findings suggest that translational research between the different areas could benefit professionals across domains. 35
