This is because the string (content_type) type of my grouping aggregate query is of type Text

Reason analysis:
When using term query, the type of the query keyword on ES must be keyword rather than text because it is an accurate match. For example, if your search condition is “name” : “Cai Xukun”, then the ES type of the name field must be keyword rather than text
In es, only the keyword type string can use AggregationBuilders. Terms (” aggs – class “) to group aggregation and grouping want to query, according to the specified keyword attribute of grouping field is ok (below);

How do we change that in our Java code?Below, just add “.keyword”
