When loading documents, memory can be saved by loading only those portions of the DOM that are required by a given script. For example, if you only want to log a list of section names in a document, you do not need to load the entire tree of nodes that lie beneath the sections.
These strategies are provided:
bqDatamodelUpgradeStrategy—All data model and query sections
bqJavascriptUpdateStrategy—Dashboard sections
bqToolbarUpgradeStrategy—Image resources and all dashboard sections
bqDashboardReportStrategy—All dashboard and report sections, plus the DocCompMoniker.Depend of other sections
bqTopLevelSectionsStrategy—All sections and their user value nodes
bqIndexingStrategy—A large subset of the nodes under queries, pivots, charts, reports, and dashboards
To load the entire document, use null for this parameter.
