Hi-
As the search business owner here at NI, I would like to clarify why you are seeing this behavior from the search engine. First, we exclude the Discussion Forums from the "Entire Site" search on the main page on purpose. This is to keep the initial results from being too overwhelming. The Developer Zone and Support section searches do include the Forums, as they are mostly technical content related. All 7 results within the DevZone search were from the Forums, hence why there weren't any results on the "Entire Site" search.
As for the query itself, the term [iviconfigstore] is a shortened version of the actual name [ivi configuration store], as you mentioned. Without the documents being tagged with or actually using that term, there isn't a way for the search engine to realize they are referring to the same item. Jason modified the KnowledgeBase article to include the shortened term so that future searches will pick it up.
We appreciate your feedback, and I hope this explains the behavior you saw. If you have any other concerns or questions, please let me know.
Thank you -
