# A page is counted as an unique URL in spider mode, or an indivdual file in offline mode. For example, one PDF file counts as one page. One image file counts as 1 page (if image indexing is enabled). One HTML file counts as 1 page, and so on.
Prices quoted are one-time purchases. There are no on-going costs or subscription fees.
Zoom Free Edition is designed for use on small personal websites. It's a nag-free application, that lets you use Zoom with no time restrictions. It has the ability to search through Word documents, PDF files and many more.
However, if you have a bigger website, or require more support, consider purchasing the Professional Editions or Enterprise Editions.
This edition of Zoom is designed for commercial developers. It allows you to index most large sites (up to 50,000 pages) - while maintaining the speed and ease of use of Zoom! You will be able to adjust the indexer to best suit your site, and it also provides support for document types such as .DOC, .PDF, and more. Commercial developers will also benefit from the additional technical support and flexibility of this edition.
For extremely large sites (up to approx. a million pages or more depending on hardware) or a cross-site search engine spanning many different websites, we would recommend the Enterprise Edition. This edition has no restriction on the size of your website (you are only limited by the amount of memory in your indexing computer), allowing you to specify the scope and demands of your website(s) to best suit your needs. You will also be able to fine tune the indexer and support document types such as Word DOC, Acrobat PDF, Shockwave Flash, and lots more.
Licensing for use on multiple sites
Yes, the above editions of Zoom can be used for indexing multiple sites. You only need ONE license PER installation of the Indexer - so you can manage a multiple number of sites with one license if you handle all the indexing on one computer. More information here.
However, if you need to install the Indexer on multiple machines through out your organisation (e.g. you are a web hosting company or a corporation with an intricate Intranet demanding simultaneous indexing from multiple computers), then you should consider the Server License. This allows an unlimited number of installations of the indexer within any one organisation.
