Monitoring with BMC Performance Manager Express for Microsoft Search

An Indexing Service is a base service for Microsoft® Windows® 2000 or later that extracts content from files and constructs an indexed catalog to facilitate efficient and rapid searching.

Indexing Service can extract both text and property information from files on the local host and on remote, networked hosts. The files can be simply members of a selected file system or part of a virtual Web hosted by, for example, Internet Information Services (IIS).

Indexing Service extracts the content by filtering—using filter components that understand a file's format. The format could include multi-language features such as international languages and locales. A filter component implements the IFilter interface, which supplies methods to read a file to extract text and properties. Windows 2000 and Microsoft Windows XP supply filters for Microsoft Office files, Hypertext Markup Language (HTML) files, Multipurpose Internet Mail Extension (MIME) messages, and plain-text files. Indexing Service then merges the extracted information into catalogs of indexes for efficient searches

The final step in the indexing process is creation of a catalog that contains a master index (and any temporary word lists and shadow indexes) storing words and their locations within a set of indexed documents. Subsequently, searching, or querying, the catalogs for particular word combinations uses the master index as well as word lists and shadow indexes to execute queries quickly and efficiently.

Depending on the managed environment, the Indexing Service may provide data for the following elements:
