[PATCH] wildcard "?" bug: "cat" matches "ca??"
Dear all,
I am not a lucene dev subscriber and hope you can see this email. It is
an intention to patch a bug that is related to multiple(continuous)
trailing wildcards "?". For example "cat" will match "ca??" .
The problem is at the file
org.apache.lucene.search.WildcardTermEnum.java (referring to current src
download from apache), line 135. three line is added:
//to prevent "cat" matches "ca??"
if(wildchar == WILDCARD_CHAR){
return false;
}
To provide some context:
...
if (wildchar != WILDCARD_CHAR && wildchar !=
WILDCARD_STRING)
{
justWildcardsLeft = false;
}
else
{
//to prevent "cat" matches "ca??"
if(wildchar == WILDCARD_CHAR){
return false;
}
// Look at the next character
wildcardSearchPos++;
}
}
...
A patch file is attached.
Thanks!
