Known issues

Searching:

  • In searches with very generalized search criteria, there may be a numeric discrepancy between the detail page of a concept and the advanced search results. This is due to an optimization side-effect of how LexEVS handles the 'search by relationship' type searches. For details refer to #28734.
  • Certain advanced searches may result in a time out. For details refer to #28764.
  • Contains relationship results could possibly be missing some concepts.  This is due to a LexEVS issue documented at #29155.
  • For performance reasons the system prevents users from submitting single word Contains/Relationship searches.  It will ask the user to enter a more specific search criteria if the user submits such searches.

Hierarchy:

  • Concepts that are not hierarchically related to other concepts won't appear in the hierarchy tree; for example, orphan concepts.
  • "View In Hierarchy" expands too much; Expands two levels deep instead of one to include the children of all of the concepts.

Hyperlinks:

  • Hyperlinks between NCI Metathesaurus and NCI thesaurus may on occasion return "Not found" messages due to synchronization delays between the terminologies.
