This section presents an example of a table, which is currently under development, intended to provide an overview of the various search techniques presented in this document, and their applications.

Search by Term Text – Overview Table

Table assumptions:

  • Search terms are at least 3 characters (what about phrases like 'of' or very short terms like "mg" or "MI")
  • Filters should be applied
  • Case sensitivity
  • Search term preparation (and maybe SNOMED CT term preparation)

Ordering and presentation have not been considered.
