Markus Heiser e9fff4fde6 doc: proofread of the all reST sources (no content change)

Normalize reST sources with best practice and KISS in mind.

to name a few points:

- simplify reST tables
- make use of ``literal`` markup for monospace rendering
- fix code-blocks for better rendering in HTML
- normalize section header markup
- limit all lines to a maximum of 79 characters
- add option -H to the sudo command used in code blocks
- drop useless indentation of lists

Plugins

Plugins can extend or replace functionality of various components of searx.

Example plugin

name = 'Example plugin'
description = 'This plugin extends the suggestions with the word "example"'
default_on = False  # disabled by default

js_dependencies = tuple()  # optional, list of static js files
css_dependencies = tuple()  # optional, list of static css files


# attach callback to the post search hook
#  request: flask request object
#  ctx: the whole local context of the post search hook
def post_search(request, ctx):
    ctx['search'].suggestions.add('example')
    return True

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
