  1. On which basis elastic search will calculate the over result score,can
    we manipulate(customized) over all result score.

  2. what is score mode and how can we define it.

Hi Sam,

It's worth checking out the custom scoring:

and explanation docs:

to see how a score is calculated and also how you can change/create your
own custom scoring.

For java, you can take an existing querybuilder object and wrap it in a
customScore script e.g:
customScoreQuery(qb1).param("param1", 0.3).param("param2",
0.9).script("doc.score * (doc['count'].value/doc['numVotes'].value)");

Check out the customScoreBuilder doc

Hi Sam,

I'm a pretty new ES user so not sure about backwards compatibility with the
Java jar for 0.16.2. If you don't have customScoreQueryBuilder classes,
i'll defer to one of the ES experts!
