RE: clarification needed for the Ranking score
Hi, Can we use the ranking as follows when searching the term'Java' present in different fields as per the relevance scenarios mentioned in the previous mail. q= courseTitle:Java^1 AND courseTag:Java^1000 AND courseDescription:Java^100; courseTitle asc, courseDescription asc, courseTag asc; -Original Message- From: Dilip.TS [mailto:[EMAIL PROTECTED] Sent: Friday, September 21, 2007 10:40 AM To: SOLR Subject: clarification needed for the Ranking score Hi, I need a clarification regarding the SOLR Ranking. consider the scenario for searching for courses based on following relevance: a. Courses with the term in the courseTitle, courseTag and in the courseDescription would appear first b. Courses with the term in the courseTitle and in the courseDescription would appear next c. Courses with the term only in the courseTitle appear next. d. Courses with the term only in the courseDescription appear next. e. Courses with the term only in the courseTag appear last. Let me know if my understanding is correct with the following solution + (basequery) courseTitle^1 courseTag^1000 courseDescription^100; courseTitle asc, courseDescription asc,courseTag asc; How do we set the relevancy while performing a search? is there any configuration to set it in the solrconfig files? Also how do we set the Term Proximity? Could you clarify? Thanks in advance Regards, Dilip TS
Re: clarification needed for the Ranking score
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.
