SharePoint's document index allows you to search for content inside documents, and in document/item metadata.
To search for documents/items or for content in documents/items:
In the harmon.ie sidebar, click the search icon () in the navigation/search omnibox.
Optionally, select the search scope ( / ) to view search options:
This Library: <name> () to search for content in the current library (this option is only available if the current location is a library or folder).
This List: <name> () to search for content in the current list (this option is only available if the current location is a list).
This Site: <name> () to search for content in the current site.
All Locations of Site: <name> () to search for content across all site collections of <name>. You may have two search scopes with this name - one for the current site, and one for the global search site (usually the social server), if it is different than the current site. Note that the global search site scope is available from all SharePoint locations, including the All Locations view.
Type a word or phrase that you want to search for in the navigation/search omnibox.
Click the Search icon again, or press Enter, to search for your phrase in the active SharePoint site, site collections, library, or list.
To repeat a recent search, click the navigation/search omnibox while it is empty to see the last 3 search terms. Select a search term to repeat the search.
Limitation: When searching for content using the This Site / All Locations of Site search scopes, the information for the returned documents may be partial (for example, the document name may be shown with no extension). In such cases the Copy command is not available. As a work around, right-click the document and click Open Containing Folder. From there you can copy the document.
To view the search results:
Search results are displayed in the sidebar's document list. The sidebar sorts the matching items in order of relevance, as defined by SharePoint.
You can use the Visible Columns dialog to determine which columns are displayed in the search results. By default, the Icon, Name, and Path of each search result item are shown.
When selecting an item from the search results, the search context pane displays where in the document/item the searched phrase was found. The navigation search omnibox, at the top of the sidebar, shows the breadcrumbs of where the selected item is located on the SharePoint server.
