Tips for retrieving URI's for textual strings:

  1. The query must be at least 3 letters.
  2. The query field is labeled "q"
  3. The search is "google like".  It will retrieve results that contain the search string anywhere within the concept name.
  4. 10 results are the default but using the limit parameter the number can be restricted e.g. 1
  5.  Dashes should not be removed from textual strings as they are important symbols in chemical names

Tips on using results from Free Text to Concept call:

  1. To insure consistent output results use the ConceptWiki uri in the "about"  for subsequent API calls, e,g,

    primaryTopic": {
       "result": [
         "_about": ""
