Question on aggregation bucket about bluge HOT 2 CLOSED

Yes, that is the intended design of aggregations. All of the documents seen at this point of execution have matched the query, so they are all processed by the aggregations. However, depending on the sort key, and how many results you requested, the document may not be a part of the result set returned to the user.

Consider an example where you have 1000 documents. You search for the top 10 documents containing "foo", and your result set will contain the 10 highest ranking documents. However, aggregations can provide you additional information about the other documents that matched, even the ones that weren't returned to you. For example:

• how many total documents matched (100)
• how many of the 100 were updated recently (using date range aggregation)
• of the 100 matching documents, which tags were most popular (using term bucket aggregation)

So, the aggregations let us do additional processing on all the matching documents, not just the subset of matches returned to the user.
