Hi, I want to implement a custom sort in Solr based on a combination of relevance (Solr gives me it yet => score) and a custom value I've calculated previously for each document. I see two options:
1. Use a function query (I'm using a DisMaxRequestHandler). 2. Create a component that set SortSpec with a sort that has a custom ComparatorSource (similar to QueryElevationComponent). The first option has the problem: While the relevance value changes for every query, my custom value is constant for each doc. It implies queries with documents that have high relevance are less affected with my custom value. On the other hand, queries with low relevance are affected a lot with my custom value. Can it be proportional with a function query? (i.e. docs with low relevance are less affected by my custom value). The second option has the problem: Solr score isn't normalized. I need it normalized in order to apply my custom value in the sortValue function in ScoreDocComparator. What do you think? What's the best option in that case? Another option? Thank you in advance, George
