http://issues.apache.org/bugzilla/show_bug.cgi?id=32167 [PATCH]multiple wildcards ? at the end of search pattern return incorrect hits Summary: [PATCH]multiple wildcards ? at the end of search pattern return incorrect hits Product: Lucene Version: 1.4 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Search AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The problem is if you search on "ca??", the hit includes 'cat', 'CA', etc, while the user only wants 4 letter words start with CA, such as 'card', 'cash', to be returned. This happens only when multiple '?' at the end of search pattern. The solution is to check if the word that is matching against search pattern ends while there is still '?' left. If this is the case, match should return false. Attached is the patch code I generated use 'diff' ******************************************************************** --- WildcardTermEnum.org 2004-05-11 11:42:10.000000000 -0400 +++ WildcardTermEnum.java 2004-11-08 14:35:14.823610500 -0500 @@ -132,6 +132,10 @@ } else { + //to prevent "cat" matches "ca??" + if(wildchar == WILDCARD_CHAR){ + return false; + } // Look at the next character wildcardSearchPos++; } ********************************************************************** --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
