+There are some technical limitations of the xapian query parser (and\r

+\r
+perhaps. If that's really your primary goal, regexp search is\r
+overkill. Maybe you should discuss with xapian upstream the possibility\r
+of having xapian support more general wildcards. I have a vague memory\r
+of olly once saying it was not out of the question. But I might be wrong\r
+about that, it's just a half-remembered IRC discussion.\r
