We are upgrading our Utah instances to the Washington release, and our testers found out that the portal search returns inrelevant search results, especially when comparing them to google search results. We have over 40,000 public knowledge articles, and the portal knowledge search is pretty vital for our users.
After some investigation we found out that Washington release stripped the search functionality. It looks, it is no longer possible to configure the search engine to ALWAYS sort the search results by relevance.
In contrast, all search engines I know (google, yahoo, bing, duckduckgo, yandex, etc.) have this as the default setting. Actually, they do not pressent any options to change this behavior, because to show the most relevant information on top of the search results is the essence of any search engine.
We know about the existance of the 'knowledge.search.sort.field' and 'knowledge.portal_search.sort.field' user preferences, but they pretty useless in regards to set the default behavior of the search engine.
Does anyone know how to configure the portal search engine in the Washington release to always sort the results by relevance?
This would be possible by rewriting the "Knowledge Result Sort" widget, but we would like to avoid this modification.
