Properties of the same name, such as author, are searched across both HTML and Microsoft Office documents. For example, an Internet Service Provider can provide Index Server to every host on their IIS server. Index Server works directly with the file system. A user can never see a document reference in a result set if the ACL on that file prohibits their reading it. This is unlike other search engines that show users hits to all documents that meet their search, even if the user can't read the document.
Index Server can index any directory defined as a virtual root.
For applications such as a central company search server or an Internet Service Provider, Index Server can be set up to work with a central index, but point to files on other servers.

For example, searching for a word that appears in a document's abstract or summary. Searching for words or phrases within specific document types, such as within a Microsoft Excel spreadsheet or a Microsoft PowerPoint presentation.
