Conditional function score query

Elastic Stack Elasticsearch
1

Hi,

I have build a query using java FunctionScoreQueryBuilder
http://www.elasticsearch.org/guide/en/elasticsearch/reference/0.90/query-dsl-function-score-query.html
and was wondering if it possible to create a conditional scoring to the
field? For example if the field exists and count = 1, apply factionFunction
of 1.0f . And if the field existsa nd count = 2, then apply factionFunction
of 2.0f , etc etc.

Is this possible?

Thanks.

Jason

You can check out

an example of how this can be done with a Java plugin.

Thanks Jörg although we are using es version 0.90.7 and the project using
es version 1.2.1. Not sure if it support.

Anyway, I achieve similar behaviour by using range filter (from 0 to less
than or equal to 1, then boost 10f for example.) and passed that
to FunctionScoreQueryBuilder.
