<p>
The search() algorithm looks for the elements [start2,end2) in the range
[start1,end1). If the optional binary predicate p is provided, then it is used
to perform comparisons between elements.
</p>
<p>
If search() finds a matching subrange, then it returns an iterator to the
beginning of that matching subrange. If no match is found, an iterator pointing
to end1 is returned.
</p>
<p>
In the worst case, search() runs in quadratic time, on average, it runs in
<a href="../../complexity.html" class="wikilink1" title="complexity">linear time</a>.
