5655参考solr的处理方式：
/** * See: {@link org.apache.lucene.queryparser.classic queryparser syntax} * for more information on Escaping Special Characters */ public static String escapeQueryChars(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 == ';' || c == '/' || Character.isWhitespace(c)) { sb.append('\\'); } sb.append(c); } return sb.toString(); }
