---------------------------------------
Summary: escape operators
Key: LUCENE-6221
URL: https://issues.apache.org/jira/browse/LUCENE-6221
Project: Lucene - Core
Issue Type: Improvement
Components: core/queryparser
Reporter: Shaun A Elliott
The current QueryParser escape method does not escape whole word operators (OR,
AND, NOT):
{code}
public static String escape(String s) {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < s.length(); i++) {
char c = s.charAt(i);
// These characters are part of the query syntax and must be escaped
if (c == '\\' || c == '+' || c == '-' || c == '!' || c == '(' || c == ')'
|| c == ':'
|| c == '^' || c == '[' || c == ']' || c == '\"' || c == '{' || c ==
'}' || c == '~'
|| c == '*' || c == '?' || c == '|' || c == '&' || c == '/') {
sb.append('\\');
}
sb.append(c);
}
return sb.toString();
}
{code}
It would be better if these words were escaped too.
