RT 包中有NamingEnumeration<SearchResult> search(Name name, String filter, SearchControls cons) throws NamingException 这个方法，其中filter的格式在RFC 2254中有所规定 RFC 2254:http://www.ietf.org/rfc/rfc2254.txt 4. String Search Filter Definition The string representation of an LDAP search filter is defined by the following grammar, following the ABNF notation defined in [5]. The filter format uses a prefix notation. filter = "(" filtercomp ")" filtercomp = and / or / not / item and = "&" filterlist or = "|" filterlist not = "!" filter filterlist = 1*filter item = simple / present / substring / extensible simple = attr filtertype value filtertype = equal / approx / greater / less equal = "=" approx = "~=" greater = ">=" less = "<=" extensible = attr [":dn"] [":" matchingrule] ":=" value / [":dn"] ":" matchingrule ":=" value present = attr "=*" substring = attr "=" [initial] any [final] initial = value any = "*" *(value "*") final = value attr = AttributeDescription from Section 4.1.5 of [1] matchingrule = MatchingRuleId from Section 4.1.9 of [1] value = AttributeValue from Section 4.1.6 of [1] The attr, matchingrule, and value constructs are as described in the corresponding section of [1] given above. 我没有太看懂这个，所以想问一下用过这个包的同学，filter中能使用正则表达式么？如果能的话怎么去使用？
