Today, if we have 'dictionary' KP in a document in lib ref book, we point to 'Python 3 Library Reference > Built-in Types > Mapping Types — dict' as similar document because we have hard coded dict as an abbreviation for dictionary.

Going forward, please add definition strings to the list of "full headers". That way, even if we remove the abbreviation for dictionary, we can find that this document is a similar document with simscore 1.0.
