Using the 64-bit Indexer

Top  Previous  Next

The 64-bit Indexer is only available in the Enterprise Edition.

You can find the 64-bit version of the Zoom Indexer under the Start menu, in Zoom's Program folder.

Note: In most cases besides those listed below, you should run the normal 32-bit Indexer on your computer. Note that 32-bit software are fully supported on 64-bit operating systems and you do not have to use the 64-bit version just because you have 64-bit hardware or a 64-bit OS.

 
You should only need to use the 64-bit Indexer if you meet one of the following conditions:

1.You are indexing an enormous number of web pages or websites, and your index files are exceeding 2GB in size. The normal 32-bit Zoom Indexer will warn you when this happens.
2.You are indexing an enormous number of web pages or websites, and you require more than 4GB of memory and you have more than 4GB of memory installed on your computer.

Note that there is no advantage to using the 64-bit Indexer unless one of the above criteria are met.

System Requirements for Indexing

You must have a 64-bit CPU (e.g. Intel Core Duo)
You must be running a 64-bit Windows Operating System (e.g. Windows Vista 64-bit)
If your Limits require more than 4GB of memory, then you will naturally need more than 4GB of RAM installed on your computer.

Server Requirements for the CGI

You do not need a 64-bit web server to host the CGI and index files generated by the 64-bit version of Zoom. These files will run on a 32-bit web server.

However, if your web server is running older versions of Linux and BSD, you may find that it does not offer Large File Support (LFS). This means that it can not open or access any single file which is larger than 2GB in size. If you are indexing up towards a million pages or content which feature over a million unique words, then there is a good chance of hitting this limit. The CGI itself is designed to work with files larger than 2GB in size on any version of Linux and BSD which provide LFS. If you are not sure, check with your web host what version of Linux or BSD they have installed on your server and whether it features large file support. Upgrading the server to a newer version of Linux or BSD which feature LFS will address this problem.
