One thing I've heard from multiple googlers is that their internal wiki search is crap exactly because there's limited hyperlinking to give a good ranking for pages. Google's algorithm basically crunches a lot of human provided data (inbound links, clicks, dwell, etc.) into an algorithmic score, but with limited data it's not much better than tf-idf.
That's probably the same thing that you've encountered with the search appliance.
- no_wizard 6y agoWhat is tf-idf, if you don’t mind me asking
- 8note 6y agoIt's a search scoring algorithm, combining how frequently the search term is used in a document with how frequently it appears in other documents. A word that shows up in the document and no others means it gets a very high score, vs "and" shows up in every document and thus doesn't score well for any

- throwaways885 6y agoPretty much. Internal search at Google actually used these appliances for a long time. Fortunately it's still been evolved and was externalised as a Google Cloud product a few years back.
- tyrust 6y agoI think you might have to change your "is" to a "was". wiki isn't really used anymore and the internal search is really really good.
- deanCommie 6y agoYou guys don't use a wiki anymore? What replaced it? Seems some form of wiki always has value inside a company?
