+    <para>
+     From 4.0.5 on it's also possible to do parallel searches. To do this
+     you use an array of link identifiers, rather than a single identifier,
+     as the first argument. If you don't want the same base DN and the
+     same filter for all the searches, you can also use an array of base DNs
+     and/or an array of filters. Those arrays must be of the same size as
+     the link identifier array since the first entries of the arrays are
+     used for one search, the second entries are used for another, and so
+     on. When doing parallel searches an array of search result
+     identifiers is returned, except in case of error, then the entry
+     corresponding to the search will be false. This is very much like
+     the value normally returned, except that a result identifier is always
+     returned when a search was made. There are some rare cases where the
+     normal search returns false while the parallel search returns an
+     identifier.
