Although the JCR 1.0 and 2.0 specifications do not require supporting wildcards characters (e.g., '*' and '?') inside the individual terms of the full text search expression, it would be useful to have, and it would also match the behavior of Jackrabbit 2.x. The characters can escaped with a leading '\', which is the same escape character used for other characters.

The only question in my mind is whether to also support the '%' and '_' characters used in JCR-SQL2. (I'm leaning toward supporting them, unless escaped.)
