Is there a way to fetch max and min values in Sphinx?

Question

Hello,

Im using sphinx for document search. Each document has list of integer parameters, like "length", "publication date (unix)", popularity, ... .

The search process itself works fine. But is there a way to get a maximum and minimum fields values for a specified search query?

The main purpose is to generate a search form which will contain filter fields so user can select document`s length.

Or maybe there is another way to solve this problem?

Answer 1

It is possible if length, date etc are defined as attributes.

Attributes are additional values associated with each document that can be used to perform additional filtering and sorting during search.
