The boost you define in the 'multi_match' query is not being show in the
explain results, so it is not being applied to the score. It should be
displayed in the weight, i.e.
"description": "weight(DISPLAY_NAME^8:happy in 33593) [PerFieldSimilarity],
result of:"
The 'phrase_prefix' type is the issue, if you remove that type the boost
will be applied. So it doesn't look like you can combine 'multi_match'
boosting with the 'phrase_prefix' as the type.
