> Project: Lucene - Core
> Issue Type: Bug
> Components: core/queryparser
> Affects Versions: 4.9
> Reporter: Tim Allison
> Priority: Trivial
>
> Dennis Walter recently pointed out this bug on [email protected]:
> " // gobble escaped chars or find a wildcard character
> private final Pattern wildcardPattern = Pattern.compile("(\\.)|([?*]+)");
> The first group will match a literal dot ("."), while its intention seems to
> be to match a backslash and a single character. So the expression should
> instead be "(\\\\.)|([?*]+)" "
