Filter functionality has been expanded, and users are able to examine the entire list of values for each filter, as well as search for text within the filter values. In the case of numeric values, such as novelty and PubMed score, a range slider allows users to refine results. All filters also have a ‘?’ help button that allows users to view a quick definition of the filter or to visit the original source, if desired. These features are displayed in Figure 2. In addition, sub-lists are generated on entity (target/disease/ligand) pages that can be viewed in their respective list browsers. It is therefore possible to browse the list of disease or ligands associated with a specific target, or targets associated with a disease or ligand. For associated diseases, additional numeric filters such as association score and interaction scores are available, as well as ligand affinity measurements for associated ligand lists.
