Basic Indexing Features

These are the basic features of an index:

• Full-text search in Web pages
• Full-text search in formatted data such as Microsoft Word or Microsoft Excel documents
• Incremental refreshing of indexes
• Control of indexing for each virtual path
• Indexing of property values
• Indexing of text regardless of language
• Automatic index updates
• Performance monitoring
• Zero-maintenance design, 24-hour reliability
• Multithreading to take advantage of SMP computers

You can incrementally refresh an index, which means you can update an index by indexing only files that have changed. Index Server does not need to re-index all the documents in a scope.

With Index Server, a number of different performance monitors help administrators optimize their query service. These monitors measure criteria such as the number of documents that need to be indexed and how fast queries are being processed.

By design, Index Server requires little if any maintenance. Once set up, all operations are automatic, including updates, index creation and optimization, and even crash recovery if there is a power failure or if the index gets corrupted. Index Server was designed from the start to work in mission-critical environments where the server must be running 24 hours a day, 7 days a week.
