The VrSearch PHP Search Engine
The VrSearch search engine allows you to build a searchable database for your web site. Visitors can search for key words and a list of any pages that match is returned to them.
IntroductionVrSearch is a tool for allowing visitors to a website to perform a search on the contents of the site. Unlike other such tools the spidering engine is written in PHP, so it does not require binaries to be run on the server to generate the search index for HTML pages.RequirementsVrSearch has the following requirements:
- PHP 4.x or PHP 5.x.
- MySQL v4.X or MySQLi v5x
VrSearch works with PHP safe mode enabled (many web hosts set up PHP like this) or disabled. For multiple character set support, iconv must be compiled in. VrSearch follows HTML links through your site. If your site uses JavaScript or Flash menus extensively, then you may need to insert dummy links to other pages on your site for VrSearch to find them.
Optional Requirements
Optional requirements apply to the PDF and MS Word document support. If you cannot meet these requirements, you can use the online conversion mechanism instead. For PDF and MS Word support, you must either:Install a binary converter (antiword and/or xpdf). Check with your ISP that you have permission to install this and execute it from within PHP.
