lucene搜索关键词错误

问题

遇到的异常信息

: Lexical error at line 1, column 38.  Encountered: <EOF> after
at org.apache.lucene.queryparser.classic.QueryParserBase.parse(QueryParserBase.java:114)

解决办法

查询搜索时遇到了特殊字符，需要对字符串进行转义

public static String escape(String s) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < s.length(); i++) {
            char c = s.charAt(i);
            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();
    }
