Description

Search facets are patterned like TAXONOMY:60047, GO:GO:34566, disease:"Alzheimer's Disease", modellingapproach:"Petri-net", so on. A query string is often made up search keywords and these facets. To extract precise search keywords, we get rid of those facets and the rest of the query string is search keywords.
