This would probably work, but the approach has a subtle flaw. If a query has one word that matches a lot of titles, but a phrase that matches a description, the best result will be shown far too low, after all the titles.
A better approach is to weight the titles a bit higher than the description, probalby 2X to 10X higher. At Infoseek, we weighted the title 8X higher. At Inktomi, with a completely different search engine, we used 7.5X. So I'd start with this: courseTitle^8 courseTag^4 courseDescription Also, I see that you are displaying the titles alphabetically, so the weights are meaningless. Maybe you should be using LIKE in MySQL if you want to do set matching and sorting. wunder On 9/20/07 10:10 PM, "Dilip.TS" <[EMAIL PROTECTED]> wrote: > Hi, > I need a clarification regarding the SOLR Ranking. > > > consider the scenario for searching for courses based on following > relevance: > > a.
