   /**
+   * Find the cursor pointing to a number that matches the number in a contact lookup URI.
+   *
+   * <p>When determining whether two phone numbers are identical enough for caller ID purposes, the
+   * Contacts Provider uses {@link PhoneNumberUtils#compare(String, String)}, which ignores special
+   * dialable characters such as '#', '*', '+', etc. This makes it possible for the cursor returned
+   * by the Contacts Provider to have multiple rows even when the URI asks for a specific number.
+   *
+   * <p>For example, suppose the user has two contacts whose numbers are "#123" and "123",
+   * respectively. When the URI asks for number "123", both numbers will be returned. Therefore, the
+   * following strategy is employed to find a match.
+   *
+   * <p>If the cursor points to a global phone number (i.e., a number that can be accepted by {@link
+   * PhoneNumberUtils#isGlobalPhoneNumber(String)}) and the lookup number in the URI is a PARTIAL
+   * match, return the cursor.
+   *
+   * <p>If the cursor points to a number that is not a global phone number, return the cursor iff
+   * the lookup number in the URI is an EXACT match.
+   *
+   * <p>Return null in all other circumstances.
