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
- ...

As offline searches can return arbitrary results depending on the engine, the current result templates were insufficient to present such results. Thus, a new template is introduced which is caplable of presenting arbitrary key value pairs as a table.

Next steps Next steps
---------- ==========
Today, it is possible to create/run an offline engine. However, it is going to be publicly available for everyone who knows the searx instance. So the next step is to introduce token based access for engines. This way administrators are able to limit the access to private engines. Today, it is possible to create/run an offline engine.

"Is it worth to run my own instance?" is a common question among searx users. Before answering this question, see what options a searx user has. "Is it worth to run my own instance?" is a common question among searx users.
Before answering this question, see what options a searx user has.
Public instances are open to everyone who has access to its URL. Usually, these are operated by unknown parties (from the users' point of view). Private instances can be used by a select group of people. It is for example a searx of group of friends or a company which can be accessed through VPN. Also it can be single user one which runs on the user's laptop. Public instances are open to everyone who has access to its URL. Usually, these

How does searx protect privacy? How does searx protect privacy?
------------------------------- ===============================
Searx protects the privacy of its users in multiple ways regardless of the type of the instance (private, public). Removal of private data from search requests comes in three forms: Searx protects the privacy of its users in multiple ways regardless of the type
of the instance (private, public). Removal of private data from search requests
comes in three forms:
1. removal of private data from requests going to search services 1. removal of private data from requests going to search services

3. removal of private data from requests going to the result pages 3. removal of private data from requests going to the result pages
Removing private data means not sending cookies to external search engines and generating a random browser profile for every request. Thus, it does not matter if a public or private instance handles the request, because it is anonymized in both cases. IP addresses will be the IP of the instance. But searx can be configured to use proxy or Tor. `Result proxy <https://github.com/asciimoo/morty>`__ is supported, too. Removing private data means not sending cookies to external search engines and

Searx does not serve ads or tracking content unlike most search services. So
private data is not forwarded to third parties who might monetize it. Besides
protecting users from search services, both referring page and search query are
hidden from visited result pages.

Also, public instances without proper protection are more vulnerable to abusing the search service, In this case the external service in exchange returns CAPTCHAs or bans the IP of the instance.

Furthermore, as the default settings of their instance is editable, there is no need to use cookies to tailor searx to their needs. So preferences will not be reset to defaults when clearing browser cookies. As settings are stored on their computer, it will not be accessible to others as long as their computer is not compromised.

---------- ==========
Always use an instance which is operated by people you trust. The privacy features of searx are available to users no matter what kind of instance they use. Always use an instance which is operated by people you trust. The privacy

If someone is on the go or just wants to try searx for the first time public instances are the best choices.
