Question

大家好我正在尝试构建一个搜索ES搜索匹配的搜索引擎，该界面有一个动态的点击计数器，每次按键后都会更新，我正在寻找一种方法来验证，解决方法或捕获一个当用户使用双引号搜索时抛出的异常，例如：

a >> 4500 hits
ab >> 1200 hits
ab" >> massive stack trace
ab"c"> 250 hits

筹码：

有什么建议吗？请询问您是否需要任何其他信息。

尝试/捕获无法捕获异常的块：

def query_str = buildQuery(params)
log.debug("count query: ${query_str}");
log.debug("enter try:");
try{      
  def search = esclient.count {
    indices "something"
    types "somethingelse"
    query {
      query_string (query: query_str)
    }
  }
}
catch ( Exception e ) {
  log.error("The Query is invalid!");
  result.hits = 0;
}

这看起来像是在v0.19.9中修复的错误。从v0.19.9开始，elasticsearch应返回更合理的错误消息。

Netty异常未正确捕获
