  I have a scenario of where the standard Full-Text search identifies keywords but Semantic Search does not recognize them as keywords. I'm hoping to understand why Semantic Search might not recognize them. The context this is being used in medical terminology and the specific key words I noticed missing right off the bat were medications.

  For instance, if I put the following string into a FT indexed table

  'J9355 - Trastuzumab (Herceptin)'

  AND

  'J9355 - Trastuzumab emtansine'

  The Semantic Search recognized 'Herceptin' and 'Emtansine' but not 'Trastuzumab'

  Nor in

  'J8999 - Everolimus (Afinitor)'

  It did not recognize 'Afinitor' as a keyword.

  In all cases the Base of Full-Text did find those keywords and were identifiable using the dmv

  sys.dm_fts_index_keywords_by_document.

  It does show the index as having completed.

  Any thoughts on why certain words might not be picked up while others would be? Could it be a language/dictionary issue? I am using English and accent insensitive settings.

  Thanks

  Brad
