Search filters

In SNOB you can define your own search filters, based on concept status and/or the top-most category of a concept. SNOB contains two standard filters, Active concepts and Inactive concepts.

Below Advanced rules you can specify three kind of rules, which may also be negated:

• Concepts subsumed by, ie descendant of
  For each concept matching the search term, SNOB will check if that concept is [not] equal to or subsumed by the concept specified in the rule.
• Concepts that are the tail (ie left-hand side) of a relationship
  For each concept matching the search term, SNOB will check if that concept has a relationship that is [not] equal to or subsumed by the specified relationship.
• Concepts that are the head (ie right-hand side) of a relationship
  For each concept matching the search term, SNOB will check if that concept is the right-hand side of a relationship that is [not] equal to or subsumed by the specified relationship.
