Lucene Core&160; is an open-source search software, provides Java-based indexing and search technology, as well as spellchecking, hit highlighting and advanced analysis/tokenization capabilities. Luke is a handy development and diagnostic tool, which accesses already existing Lucene indexes and allows you to display and modify their content.
Luke is awesome, but often times it is not feasible to inspect an index on a remote machine using a GUI. That's where Clue comes in. You can SSH into your production box and inspect your index using your favorite shell
Another important feature for Clue is the ability to interact with other Unix commands via piping, e.g. grep, more etc.

This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.
