Migrating ElasticSearch Java API FacetFilter (in early version) to simliar Aggregation in ES v5.5.3

I am migrating a Grails application using Elasticsearch Java v0.93 to version 5.5.3. One of the challenges I am facing is to migrate Facet Filter to a similar Aggregation.

Following is the code from the early version of Elasticsearch Java API:

FacetBuilders .termsFacet("f").field("brand").size(50) // Your facet .allTerms(true) .facetFilter( // Your filter here FilterBuilders.boolFilter() );

As per the Elasticsearch Java API "Facets has been removed and it is recommended to use filter aggregation or filters aggregation.

Thanks!

It's been a while, but basically you want to get the 50 most common (brand) terms without a filter? That should be a straight forward terms aggregation

@xeraa what do you mean by without a filter? Also, FilterBuilders.boolFilter() has other must filters which I didn't mention in this question.

Please try below query to migrate facets to Aggregation

facets

Aggregation

AggregationBuilders.filter("Filter By Some Property", QueryBuilders.termQuery("some Field", "value")) .subAggregation(AggregationBuilders.terms("Group By Some Other property").field("brand").size(50));

Here you can use any type of query in filter method. Have used Term Query just as an example.

filter

Term Query

Hope it helps!!
