I would like to migrate from High Level rest Java to new java api client.
I have old method using the source filtering feature in High level rest java, like
In new java api, I knew the SourceBuilder is not available, but shoud some function be used like fetchSource() function to let me custom return fields of query?
You can try this part
SearchRequest searchRequest = new SearchRequest.Builder()
.source(SourceConfig.of(s -> s.filter(f -> f.includes(List.of("fieldA", "fieldB")))))
SourceConfig give access to include and exclude fields.
Thank you for your example.
