+=item smart_search OPTION => VALUE ...
+
+Accepts the following options: I<search>, the string to search for.  The string
+will be searched for as a customer number, phone number, name or company name,
+as an exact, or, in some cases, a substring or fuzzy match (see the source code
+for the exact heuristics used); I<no_fuzzy_on_exact>, causes smart_search to
+skip fuzzy matching when an exact match is found.
+
+Any additional options are treated as an additional qualifier on the search
+(i.e. I<agentnum>).
+
+Returns a (possibly empty) array of FS::cust_main objects.
