Introduction

Global Search will have the feature of searching keywords within the entire Moodle site across modules keeping the security intact. It will also be able to search for keywords from externally attached files. (PPTX, PDF, etc.)

Installation

For using Global Search, users will have to install the PHP Solr PECL extension on server.

Following are the two dependencies of the extension:

• CURL extension (libxml2 2.6.26 or later is required)
• LIBXML extension (libcurl 7.15.0 or later is required)

Test whether the required extensions are installed or not by executing the following in a php file (Remember to delete the file as it has important information about your system):

echo phpinfo();

If the system does not have required versions of libcurl or libxml libraries, follow the steps given below:

1. For libcurl:

wget http://curl.haxx.se/download/curl-7.19.6.tar.gz
tar -zxvf curl-7.19.6.tar.gz
cd curl-7.19.6
sudo ./configure --prefix=/root/custom/software
sudo make 
sudo make install

1. For libxml:

wget ftp://xmlsoft.org/libxml2/libxml2-2.7.6.tar.gz
tar -zxvf libxml2-2.7.6.tar.gz
cd libxml2-2.7.6
sudo ./configure --prefix=/root/custom/software
sudo make
sudo make install

Next, you will be ready to install the PECL extension for Solr by cloning the following repository for Solr 4.x:

#git clone https://github.com/lukaszkujawa/php-pecl-solr.git
#cd php-pecl-solr/

If the above two dependencies were already installed, execute:

sudo ./configure 

Else, if you just compiled libcurl from source and installed using "/root/custom/software" as the --prefix, execute :

sudo ./configure --with-curl=/root/custom/software

OR, if you just compiled libxml from source and installed using "/root/custom/software" as the --prefix, execute :

sudo ./configure --with-libxml-dir=/root/custom/software

OR, if you just compiled both the libcurl and libxml libraries from source and installed using "/root/custom/software" as the --prefix, execute :

sudo ./configure --with-curl=/root/custom/software --with-libxml-dir=/root/custom/software

sudo make
sudo make install
