Hi Gustatec,
Relevancy tuning is really *huge* area, check this book when you have a chance: https://www.manning.com/books/relevant-search Default Solr sorting is based on TF/IDF algorithm; and sorting is not necessarily ‘relevancy’ Trivial solution for clothes store domain would be this one, better to explain using examples: Product 1 ======== Name: "Russell Athletic Men's Basic Tank Top" Categories: “Shirt”, “Sleeveless Shirt”, “Tank Top” Product 2 ======== Name: "Russell Athletic Men's Cotton Muscle Shirt" Categories: “Shirt”, “Sleeveless Shirt”, “Tank Top” You may notice that first product has “Top” repeated twice in product name and category; and second one has “Short” repeated twice. Now having this real-life example you can play with boost query, boosting results containing words from category name in their product name. category:”Tank Top” & bq:”name:tank^10 OR name:top^5" Solr provides “boost query” to tune sorting of output results, check “bq” parameter in the docs at https://cwiki.apache.org/confluence/display/solr/The+DisMax+Query+Parser I went from real-life scenario; your scenario and possible solutions could be very different. I had recently assignment at well-known retail shop where we even designed pre-query custom boosts so that we can customize typical (most important for the business) queries as per business needs Thanks, -- Fuad Efendi (416) 993-2060 http://www.tokenizer.ca Search Relevancy, Recommender Systems On November 4, 2016 at 10:57:02 AM, Gustatec (gusta...@gmail.com) wrote: Hello everyone! I'm currently using Solr in a project (pretty much an e-commerce POC) and came across with the following sort situation: I have two products one called Product1 and other one called Product2, both of them belongs to the same categories, Shirt(ID 1) and Tank-Top(ID 2) When i query for any of these categories, it returns both of the products, in the same order. Is it possible to do some kind of grouping sort in query? So when i query for category Shirt, it returns first Product1 then Product2 and when i do the same query for category Tank-Top it would return first Product2 then Product1? By asking that i wonder if its possible to make a product more relevant, based on the query. So product1 relevancy would be Category ID | Priority 1 | 1 2 | 2 And product2 would be Category ID | Priority 1 | 2 2 | 1 Is it possible to achieve this "elevate" funcionality in query? i thought in doing a <category_name>_sort field for all categories, but we are actually talking about a few hundred categories, so i dont know if would be viable to create one sort field for each one of them in every single doc... Ps: I asks if its achievable that in query because i dont know if there is any other way of changing the elevate.xml file without having to restart my solr instance Sorry for my bad english, and thanks in advance! -- View this message in context: http://lucene.472066.n3.nabble.com/Different-Sorts-based-on-Different-Groups-tp4304516.html Sent from the Solr - User mailing list archive at Nabble.com.
