Hi, We have a quite complex requirement concerning scoring logic customization, but but I guess it's quite useful and probably something like it was done already.
So we're searching through the product catalog. Product have types (i.e. "Electronics", "Apparel", "Furniture" etc). What we need is to customize scoring of the results so that top results should contain products of all different types which match the query. So after finding all the products matching the query we want to group results by product type. Then for every product type take corresponding sub-set of results and in every of the sub-sets assign scores with the following logic. Assign score 5 to the first 20% of results, then assign score 4 to the next 15% of results, and so on. Particular percent values are configured by the end user. How could we achive it using Solr? Is it possible at all? Maybe we should implement some custom ValueSource and use it in a function queries? -- Andrew Klochkov
