The default WildcardQuery only supports:
'*' (star) is the wildcard in WildcardQuery for zero or more chars.
'?' is exactly one char
Zero or exatly one char can only be done with a RegexpQuery:
https://lucene.apache.org/core/4_7_0/core/org/apache/lucene/search/RegexpQuery.html
Here is the syntax:
https://lucene.apache.org/core/4_7_0/core/org/apache/lucene/util/automaton/RegExp.html
Query parser supports regex queries since 4.0 with "/" as delimiter:

Subject: Lucene Wildcard for zero or one character
Hello,
does Lucene provide a zero or one character wildcard (like ? in Perl
RegEx)?
Example of what I mean:
"house%" finds "house" and "houses"
As far as I know in Lucene the ? wildcard is for exactly one character,
but I
need a zero or one character wildcard.
Best regards,
