Systems and methods for scoping a search. When a content index for
electronic data is built, one or more scope restrictions are included in
the content index. The scope restriction may be, for example, a root
folder identifier, a mailbox identifier, or a Uniform Resource Locator
(URL). Because the scope restriction is included in the content index
random access of the property store to determine the scope is avoided.
Rather, the scope restriction is implicitly added to a search that uses
the content index. By including a scope restriction in the search query,
the search results identified from the content index are limited to
results that match the scope restriction. Advantageously, the effect of
including the scope restriction in the search is ignored if the search
results are relatively small or when including the scope restriction
provides little benefit.
