Overview

Package search describes and answers Camlistore search queries.

Many of the search methods or functions provide results that are ordered by modification time, or at least depend on modification times. In that context, (un)deletions (of permanodes, or attributes) are not considered modifications and therefore the time at which they occured does not affect the result.

Constants

const MaxImageSize = 2000

MaxImageSize is the maximum width or height in pixels that we will serve image thumbnails at. It is used in the search result UI.

Functions
