Ryan Ernst f32692208e Add explanations to script score queries (#46693) (#47548) ... While function scores using scripts do allow explanations, they are only creatable with an expert plugin. This commit improves the situation for the newer script score query by adding the ability to set the explanation from the script itself. To set the explanation, a user would check for `explanation != null` to indicate an explanation is needed, and then call `explanation.set("some description")`.		2019-10-03 21:05:05 -07:00
