I need to collect publications by others on connexins & how they relate to our studies
I want to find out whether there are any new publications on the mechanism that underlies Golgi cisternal maturation in yeast
I’d like to find out what kind of animal models of huntington’s diseaseare out there

Which approaches to facetted navigation work best for this domain?
Which search interface features are useful for searching the biomedical literature?
Users prefer different interface features depending on the search task
Research Questions and Hypotheses

Hypothesis
It’s better to display dynamically computed sets of facets than a complete hierarchical list

The Study
Exploratory short study with 6 bioscientists
2 faculty, 2 postdocs, 2 PhD students
Q&A on 3 search types in their work, queries, resources, systems
10-15min in person sessions
Main study with 10 bioscientists
2 faculty, 7 postdocs, 1 PhD student
Email & 1-2hr in person sessions
Side-by-side comparison of anonymysed search interface features
Per participant: 1 baseline and 1 own query

Summary of Findings, Participants’ Comments
Autocomplete is less important: “we feel pigeonholed by suggestions”
Facets are useful: “we focus and refine the search all the time”
Choose facets wisely: “a large number of facets is overwhelming”
Checkboxes are better than links: “we want to select multiple values”
Aesthetics are important but what really matters is the content

Few, query-oriented facets with specific values, in checkboxes!
Facets and results preview are useful for any search task
