VSTO Smart Tag Terms

VSTO smart tags let you easily create a smart tag by adding some terms to it.  For example, consider this simple smart tag in a VSTO worksheet project item.  It creates a smart tag that recognizes the term “Halibut”.  One caveat about using the terms collection–VSTO uses Office’s tokenizer to get words to match against terms.  The tokenizer breaks down text in the document into words.  See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/stagsdk/html/stconWhatsNew_HV01083276.asp for more information–look for “Tokenizer Feature Built Into Smart Tag Infrastructure”.  This means you can’t match a term like “Eric Carter” because the tokenizer will actually convert this into the tokens “Eric” and “Carter” and never give VSTO a token like “Eric Carter”.  If you need to match a term that includes spaces and punctuation, use VSTO smart tag’s support for regular expressions.
