cattaSearch is web/cloud-based: The user needs a browser. The rest is on the backend server - and all is open source.
The backend server side of cattaSearch consists of a web server with PHP and a relational database, MySQL.
cattaSearch 1.0 has been tested with MySQL 5.7 and 8.0 as well as PHP 7.0 and 7.4.
All cattaSearch information is stored in a database, MySQL.
The use of full-text search requires MySQL 5.6 or higher.
MySQL was first acquired by Sun Microsystems and then Oracle, but you can still download the free open source MySQL database from dev.mysql.com, the socalled Community Edition.
cattaSearch has been tested on Apache as well as Microsoft Internet Information Server (IIS).
Apache is open source and is included in most Linux distributions or can easily be installed using a Linux package manager, e.g. YAST in OpenSUSE or Synaptic Package Manager in Ubuntu.
The open source Apache web server can be downloaded from httpd.apache.org, e.g. for Windows.
Microsoft includes a web server with Windows, i.e. it is free for all Windows users, but not installed by default on desktop or workstation editions of Windows.
Here is what you do to install it - make sure you have the Windows installation CD:
After installation of Internet Information Services you might have to reapply the latest Windows service pack in order to ensure that you have the latest patches and security fixes for IIS.
PHP is the scripting language that cattaSearch is based on.
PHP is open source and is included in most Linux distributions or can easily be installed using a Linux package manager, e.g. YAST in OpenSUSE or apt in Ubuntu.
Two Windows PHP packages are available in a number of different versions, including 32-bit and 64-bit.
cattaSearch requires one specific add-on to PHP: gettext
Gettext - part of the GNU project - is an open standard for supporting different languages in an application, e.g. an English, a Danish, a French, etc. user interface.
The gettext functions implement an NLS (Native Language Support) API which can be used to internationalise applications.
Note: gettext is operating system-specific and is therefore NOT included in the cattaSearch download file.
In earlier version of PHP, gettext was not included in the installer package, but this seems to be history now.
In Windows, gettext is a separate DLL (dynamic link library) file:
Install and / or enable gettext in Windows:
php.ini, e.g. C:\PHP\php.ini, to include gettext support by removing the semicolon in front of the line:
extension_dir = C:\PHP\ext
upload_max_filesize = 10M
cattaSearch runs with the PHP.INI parameter register_globals = Off - but of course also with register_globals = On.
