Cuong, I have implemented sponsored words for a client. I don't know if my working can help you but I will expose it and let you decide.
I have an index containing products entries that I created a field called sponsored words. What I do is to boost this field , so when these words are matched in the query that products appear first on my result. 2008/6/3 climbingrose <[EMAIL PROTECTED]>: > Hi all, > > I'm trying to implement "sponsored results" in Solr search results similar > to that of Google.
