Can anyone help with a query to do a negative boost on documents based on an array of values that i have when creating the query postData?  
Example:

1. A user has viewed 100 images and those 100 image id's are stored in an array somewhere else.
2. I now want to create a query that retrieves a set of documents that will include documents with these id's however they're demoted down in the result set

Thanks
