Can _search_with_cluster also cluster the result if content is of type "attachment"?


(Pratikshya Kuinkel) #1

You won't be able to cluster the base64 encoded string directly. But, if you specify "fields" when firing your query, you will be able to do that. Please have a look at the following gist:


You will now be able to use files.file when clustering your result. However, if you have an array of attachments, it will treat all the files as a single file when clustering. Only way we can access them as array is through _source, which again will only return base64 encoded string. Not sure how to get around this issue. But for single files, using "field_mapping": { "title":[fields.files.file"]} should work. Let me know how it goes.
