Hi,
My experience with Elasticsearch is limited and I am trying to migrate some code from using ES 1.7 to ES 2.1.
In ES 1.7, the FilterBuilders.boolFilter().must() can accept an array of FilterBuilder and return a single one but the QueryBuilders.boolQuery().must() in ES 2.1 would only accept a single QueryBuilder.
What should I do in this situation?
Thank you.
Andy
