Plugin entry points
|
|
===================
|
|
|
|
Entry points (hooks) define when a plugin runs. Right now only three hooks are
|
|
implemented. So feel free to implement a hook if it fits the behaviour of your
|
|
plugin.
|
|
|
|
Pre search hook
|
|
---------------
|
|
|
|
Runs BEFORE the search request. Function to implement: ``pre_search``
|
|
|
|
Post search hook
|
|
----------------
|
|
|
|
Runs AFTER the search request. Function to implement: ``post_search``
|
|
|
|
Result hook
|
|
-----------
|
|
|
|
Runs when a new result is added to the result list. Function to implement:
|
|
``on_result``
