+ *
+ * @param aSearchString
+ *        The string to compare against.
+ * @param aURL
+ *        The URL to test for an AutoComplete match.
+ * @param aTitle
+ *        The title to test for an AutoComplete match.
+ * @param aTags
+ *        The tags to test for an AutoComplete match.
+ * @param aVisitCount
+ *        The number of visits aURL has.
+ * @param aTyped
+ *        Indicates if aURL is a typed URL or not.  Treated as a boolean.
+ * @param aBookmark
+ *        Indicates if aURL is a bookmark or not.  Treated as a boolean.
+ * @param aOpenPageCount
+ *        The number of times aURL has been registered as being open.  (See
+ *        mozIPlacesAutoComplete::registerOpenPage.)
+ * @param aMatchBehavior
+ *        The match behavior to use for this search.
