I tried .* too but it gave the same error. I think it's a bug.
I solve it using SpanTermQuery where the search phrase is broken into
day
of
every
months
and I nest these SpanTermQuery into SpanNearQuery with slop > 1.
Thanks.

What analyzer did you use for your text? Again, that is not a valid
regular expression. But also, you're using a single long string of
several words within your SpanRegexQuery term. What you probably
want is a SpanNearQuery of those fixed terms along with a ".*"
SpanRegexQuery in the wildcarded spots, and then you could nest that
inside a SpaneFirstQuery.

It's likely a bug that you get this particular error, but I think
you'll get around it by solving the above mentioned issues with your
query.
