Scripting Rules

Perceptive Enterprise Search scripts provide you with an way to extend the indexer using scripting languages such as Microsoft® Visual Basic® Scripting Edition (VBScript) and Microsoft® JSCRIPT, adding the flexibility to create advanced file indexing rules, index foreign file systems, or index documents not currently handled natively by the Perceptive Enterprise Search engine.

Perceptive Enterprise Search scripts allow you to extended the engine, allowing you to:

• Inject external metadata and index it as if it was part of the document.
• Create advance indexing rules controlling what documents get indexed.
• Create ASP style templates to index "virtual", non-disk based content. This may include SQL databases, report, RSS feeds, or any third party system that has a COM interface.
• Foreign file systems such as a Document Management System, WEBDAV or Content Management System.

The Perceptive Enterprise Search engine loads your script looking for particular methods, dependent on purpose of your script. Your script is loaded once, and kept loaded. You may include global variables to keep state in your script.

Perceptive Enterprise Search scripts are stored per index, in the ISYSSCRIPT.XML file. The ISYSCRIPT.XML is an XML file that stores the one or more scripts for any given index. You can modify this file by hand, or use the built-in wizard.
