I am looking for a way to prevent fields that users shouldn't be able to know exist from contributing to the score. The goal is to provide a way to essentially hide certain fields from requests based on an access level provided on the query. I have managed to make terms that users shouldn't be able to see not impact the score by implementing a custom Similarity class that looks at the terms payloads and returns 0 for the score if they shouldn't know the field exists. The issue however is that I don't have access to the request at this point so getting the users access level is proving problematic. Is there a way to get the current request that is being processed via some thread local variable or something similar that Solr maintains? If not is there another approach that I could be using to access information from the request within my Similarity implementation? Any thoughts on this would be greatly appreciated.
