Very very interesting.
I went ahead and turned on the AllowLeadingWildcard toggle and
everything works just as expected now, which is odd in a way.
I'm still not certain why a search for '\*ache*' would be considered to
have a leading wildcard. I'm searching for the literal * character
here which I would have assumed would be a completely fine thing to do
in a search, but somehow its triggering the leading wildcard checking
logic.
Well, anyhow thanks much for the suggestion, things are working properly
now.

Which looks to me alot like something akin to the
AllowLeadingWildcard stuff that comes along with wildcardqueries.
But, the odd thing is the leading character in my search string ISN'T
*, its the escaped star character, which I would have thought would
work with no problems at all.
Have I stumbled across a bug here?
Did you setAllowLeadingWildcard(true)?
/**
* Set to <code>true</code> to allow leading wildcard characters.
* <p>
* When set, <code>*</code> or <code>?</code> are allowed as
* the first character of a PrefixQuery and WildcardQuery.
* Note that this can produce very slow
* queries on big indexes.
* <p>
* Default: false.
