大家好，我正在尝试构建一个搜索引擎来搜索 ES 以查找匹配项，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、解决或捕获异常当用户使用双引号搜索时抛出，例如：
a >> 4500 hits
ab >> 1200 hits
ab" >> massive stack trace
ab"c"> 250 hits
堆栈：

有什么建议么？请询问您是否需要任何其他信息。
未能捕获异常的 Try/Catch 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;
