I am using msearch API to control filtering and query across different indices to return a global result set. Is there a way I can boost the score of the results of one search request over another? I have tried to use the indices\_boost parameter to boost the index that I want to boost results for and it is not changing the score.

It looks like this appears to be working properly, but my sorting of results in my application code wasn't working properly. This can be closed.
