Indexing a repository is the administrator’s job, and you could think you don’t need to know what is indexing, and whether the repository you are using is indexed or not. However, indexing can have an impact on the search experience. When a repository is indexed, a data structure, the index, is created to store information. The information can either be on the files’ properties only or on the properties, and the content of the files. Searching an indexed repository facilitates a rapid retrieval of documents because it does not require scanning all files but only searching the index. In this guide, when referring to an indexed repository, we mean a repository for which both content, and properties are indexed, and not only properties. When the repository is indexed, you run full-text queries when using the simple search box or the Contains field of the advanced search window. When the repository is not indexed, the query is converted into a query on the most relevant properties: name, title, and subject. This mechanism is transparent, and enables you to retrieve the most relevant results.
