To improve the usability of AntWeb's advanced search, I experimented with using a faceted search approach, allowing the user to adjust how they wanted to approach their data by four (4) facets.
As a first step, I broke down what those four facets were, and what uas unique to them in terms of search, versus what applied to all four.
Here we have rough information design showing the different searches, color coded simply to highlight to the user that s/he has swapped to a different facet.
