Search results cache
===================

Beginning from version 3.1.4 mnoGoSearch supports search results cache.
Search results cache allows very fast search.cgi report on recently
used queries as well as user's navigation though the pages
of the same result.

Search results cache is disabled by default. You may use "Cache yes"
search.htm command to enable results caching.

Search cache is located in $PREFIX/var/cache/ subdirectory, where
$PREFIX is mnoGoSearch installation base directory. Each result is
stored in a separate file.

Note that search results cache is not deleted automatically. You
have to delete it every time after indexer's work to avoid displaying 
non-recent cached results. It is also reasonable to insert cache cleaning 
into system crontab, for example once a day. To clean cache just remove all 
files in $PREFIX/var/cache/ directory. For example:

/bin/rm -f /usr/local/mnoGoSearch/var/cache/*
