2.18.1 Main Catalog

  • Article

Main catalog is a full-text index catalog whose full-text index components contain the data extracted from all the properties that were designated to be placed in the full text index by the metadata schema.

The content index files in the main catalog MUST contain content index keys generated from the words extracted from the Properties of the indexed items. The Properties that are included are the ones that are marked "FullTextQueriable" as defined in [MS-QSSWS] section 3.1.1.3.

The basic scope index files in the main catalog MUST contain the basic scope index keys for all values of the Properties designated to be placed in the scope index files by the metadata schema. The Properties that are included are the ones which are marked "Scopable" as defined in [MS-QSSWS] section 3.1.1.3.

In addition, the basic scope index files store basic scope index keys generated from string values for the pidSiteScope property. For each item, these keys record all generated string values for folders in the URL of the item.

Example:

For an item "http://server/folder/document.htm", the string values "server", "http://server", and "http://server/folder" will be generated.

The compound scope index files MUST contain one scope index record for each compound scope index defined in the search application with a compound scope index key constructed from compound scopeID.
