[svn r13377] Added search plugin to default Dokeos package. This is an attempt at integrating the search plugin better and make it available to all, although it requires a server-side installation. Might be removed in the future if proves inappropriate.

+Dokeos Search Plugin Installation Guide
+=======================================
+
+1. Introduction
+---------------
+This search plugin is composed of everything you need to get up and
+running with a full-text search feature on your Dokeos portal. However,
+this installation is not easy, and if you are not familiar with the
+term "indexing", or with the configuration of a Linux server, we
+highly recommend you seek advice from a qualified system administrator
+to help you doing this. Of course, the Dokeos company, for which I am
+directly working, offers this kind of services. Feel free to contact
+info@dokeos.com for a quote.
+
+This search plugin relies on a search server, called MnogoSearch, which 
+has to be installed independently on a Linux server (the Windows 
+version, sadly, is not GPL nor free to use).
+The following installation guides you through the steps of installing
+the server on a Debian or Ubuntu computer, but you might probably
+succeed in installing it on other architectures.
+
+Dokeos has made considerable efforts to have MnogoSearch integrated
+into the latest versions of PHP, but it would never have succeeded
+without the help of pierre.php@gmail.com who did all the technical 
+work.
+
+2. Installing files
+--------------------
+All the "conf" files and the "search.xml.php" file in this package
+need to be revised to configure properly. Most of all, you should look
+for a "DBAddr  mysql://db_user:db_pass@db_host/db_name/?dbmode=single"
+line in the server files to make sure it is using the correct database
+credentials.
+
+Now you will see that there are two directories in this plugin.
+The "client" directory needs to stay there. The "client/www" directory
+contains a PHP script that needs to be copied at the root of your
+Dokeos portal (this will later give the indexing server an access to 
+your Dokeos portal).
+
+The "server" directory has to be moved on the indexing server (which
+might be the same as your Dokeos portal's server if it is not too
+overloaded).
+
+This "server" directory contains three subdirectories.
+The "server/etc" directory contains the configuration of the
+mnogosearch server, which typically on Debian will be located in
+/etc/mnogosearch. Once you have installed the mnogosearch server, 
+you can pretty much overwrite the configuration with the files 
+contained in "server/etc", as they are already customised for indexing
+Dokeos.
+
+The "server/cron.d" directory contains an optional file that you might 
+want to put in /etc/cron.d, so that the indexing will be run every night
+5.00am.
+
+The "server/www" directory contains files that should be made available
+to the public, to access idexation results. Feel free to put these, for
+example, in /var/www/mnogosearch on your indexing server if that's where
+Apache takes its public files.
+
+3. Installing the search server (MnoGoSearch)
+---------------------------------------------
+The mnogosearch server installation comes in two parts:
+A) installing the mnogosearch indexing server itself. This can be done
+with a simple:
+  sudo apt-get install mnogosearch-common mnogosearch-mysql
+B) installing the PHP5-mnogosearch bindings. This can be done by using
+the PECL command-line installer
+  sudo pecl install mnogosearch-1.0.0
+
+Once the server is installed, you may need to install server specific
+additional programs to allow your indexer to go into documents (PDF,
+Word, Excel, etc) and index the contents of these documents as well.
+
+You can find a list of programs supposed to be there in the 
+server/etc/indexer.conf file. Search for "pdftotext" and you will find
+the lines nearby all define a program used to translate a document
+into pure text before indexing it. Make sure you are able to launch
+all of these commands on the command line. If you can't, the indexing
+server is not likely to be able to do it either...
+
+4. Creating the DB and Dokeos user
+----------------------------------
+In order to keep the index data, mnogosearch requires a database to
+store this data. It is recommended to create an alternative user, with
+access to only one database to do this.
+
+Once this user is configured and the DBAddr line is configured in 
+server/etc/indexer.conf, you can create the database structure by 
+calling (on the indexing server):
+ indexer -Ecreate indexer.conf
+
+The next step is to create a Dokeos user for the purpose of indexing 
+your courses (the user needs access to all courses to be able to index
+them). Create a simple user in the Dokeos administration interface. Then
+get his ID (you can get it by hovering the edition icon in the users 
+list: the user id is the number that shows after "user_id" in the URL)
+and use it inside indexer_login.php to replace the 'xxx' value.
+
+Also configure the IP address and the host name of the indexing server
+inside this file.
+
+Once these two steps are complete, you can start the first indexation
+of your portal, by calling, on the command line of your indexing server:
+  indexer -N10 index.conf
+N10 lets you limit the number of simultaneous threads that your indexing
+server will be allowed to use. More than 10 might put your Dokeos portal
+in overload. You might want to reduce this number to 3 for light servers.
+
+5. Installing the plugin
+------------------------
+Installing the plugin is done by dispatching the files contained in 
+this plugin as described in "2. Installing files", and configuring the
+various *.conf.php files as well as server/etc/indexer.conf and 
+server/www/search.xml.php
+
+Once the files have been moved and configured, you will still need to 
+index some data, then activate the plugin inside the Dokeos
+administration panel. Then, basically, you should be able to use
+the plugin straight away.
+
+6. International use
+--------------------
+To keep this plugin small, we had to remove a considerable amount of
+international-parsing helper files. If you need one for your language,
+it may well be included in the default installation file for the
+Debian mnogosearch-common package.
+
+If not, you should check more recent versions of mnogosearch on its
+website: http://www.mnogosearch.org/
+
+7. Seek help
+------------
+Commercial suppport is available for the configuration and remote use
+of this plugin at info@dokeos.com
+If you have plenty of time to learn it by yourself or any other reason,
+you might find some free help on our forums: http://www.dokeos.com/forum
