Hi, Rob!
The difference between the two result sets you got when you ran the query for 'pruritus' is due to the search criteria that were used for the queries. When you go to the Library Reference Look-up, the default search criteria are: "Starts With" + "Primary Name" + "Any Category" + search value. When you are inside of a specific area, such as "Conditions", instead of "Any Category", the specific type of information is searched.
Please note in the image below, that the results you reported (8 vs 2) are consistent with the search criteria being used. Some of the results that show up for 'pruritus' have been categorized as 'symptoms' and not 'conditions'.
Codes will be upgraded in future releases of HealthFrame. Even though the library modules are expressible as importable XML structures, there is significant categorization effort that is done prior to importing code updates into the application.
Thanks for the question!
