replace -_score with -score #40

Closed stevemar closed 6 years ago

stevemar commented 6 years ago

we had a comment on an old PR [1] to replace -_score with -score in query_builder.py. The comment is still valid from a code point of view [2], but i'm not sure if it's a valid change/suggestion, so i'm filing this bug so we don't forget about it.

I just started seeing this issue in another Watson Discovery app which also used the '-_score' as the sort key. It returned the error "Error: [_score] unknown field [unmapped_type], parser not found".

Changing to '-score' fixed the problem.
