Say I have 3 different fields, A of text type, B of int type, C of date type. I other query conditions for all 3 fields. In addition to this, I want to give more weightage to field C then B then A. ie A is looking for text having word 'xyz' and it haves less priority,say weight of 1 B is looking for values greater than 100 and it have some priority, say weight of 5 and C should have a date greater than June 2022 and it has a higher priority of weight 10.
