The ''advanced search'' allows for ''search definitions'' that correspond to more than one ''criterion'' and/or ''criteria'' node(s). Search definitions can have ''linked items'' (activities linked to a land, victims linked to an accident, etc.). A ''criterion'' can be defined by paring down its ''attributes'', ''operators'' and ''values''.
Searches defined with the advanced search engine can be ''saved'' in the ''Saved Searches''.
