Provides classes and methods for browsing Items in DSpace by whatever is specified in the configuration. The standard method by which you would perform a browse is as follows:

• Create a BrowserScope object. This object holds all of the parameters of your browse request
• Pass the BrowserScope object into the BrowseEngine object. This object should be invoked through either the browse() method or the browseMini() method
• The BrowseEngine will pass back a BrowseInfo object which contains all the relevant details of your request

Browses only return archived Items; other Items (e.g. those in the workflow system) are ignored.

Using the Browse API

An example use of the Browse API is shown below:

    // Create or obtain a context object
    Context context = new Context();

    // Create a BrowseScope object within the context
    BrowserScope scope = new BrowserScope(context);
    
    // The browse is limited to the test collection
    Collection test = Collection.find(context, someID);
    scope.setBrowseContainer(test);
    
    // Set the focus
    scope.setFocus("Test Title");
    
    // A maximum of 30 items will be returned
    scope.setResultsPerPage(30);
    
    // set ordering to DESC
    scope.setOrder("DESC");

	// now execute the browse
	BrowseEngine be = new BrowseEngine();
    BrowseInfo results = be.browse(scope);

In this case, the results might be Items with titles like:

Tehran, City of the Ages
Ten Little Indians
Tenchi Universe
Tension
Tennessee Williams
Test Title              (the focus)
Thematic Alignment
Thesis and Antithesis
...

Browse Indexes

The Browse API uses database tables to index Items based on the supplied configuration. When an Item is added to DSpace, modified or removed via the Content Management API, the indexes are automatically updated.

To rebuild the database tables for the browse (on configuration change), or to re-index just the contents of the existing tables, use the following commands from IndexBrowse:

A complete rebuild of the database and the indices:

[dspace]/dsrun org.dspace.browse.IndexBrowse -f -r

A complete re-index of the archive contents:

[dspace]/dsrun org.dspace.browse.IndexBrowse -i
