Tracking support
================

Since version 3.1.2 mnoGoSearch has a query tracking support.

Note that tracking is implemented in SQL version only and
not available in built-in database.

To use tracking, you have to create tables for tracking support.
For MySQL, use create/mysql/track.txt. When doing a search, front-end 
uses those tables to store query words, a number of found documents 
and current UNIX timestamp in seconds.

To enable tracking, use:

TrackQuery yes

in "variables" section of search template.


 Query tracking is useful to have a statistics of your search engine usage. 
To make a search queries summary, you may execute, for example, this SQL
expression:

SELECT qwords,count(*),sum(found),avg(found) GROUP BY qwords;
