Erik:
Well, you wrote the book <G>. But I thought something like this
would work
TermDocs td = reader.termDocs();
WildcardTermEnum we = new WildcardTermEnum(reader, new term("field",
"c*t"));
while (we.next()) {
td.seek(we);
while (td.next()) {
report document contains term;
}
}
Although I admit I haven't tried it, so I could be totally off base. What
am I missing?

Erick - I think you're mixing things up with WildcardQuery.
RegexQuery does support all regex capabilities (depending on the
underlying regex matcher used).
A couple of techniques you could use to achieve the goal:
* Use RegexTermEnum, though that'll give you the terms across the
entire index, so maybe in your use case you could index a single
document into a RAMDirectory and RegexTermEnum on it.
* Try out SpanRegexQuery and use getSpans() to get the exact
matches.
