Hi Team,

Regular expression to search all the documents with following URL ( have shown 3 docs here)

@fields.requested\_uri: "/services/chinesedrugcontent/drugTopics/3492/json"  
@fields.requested\_uri: "/services/chinesedrugcontent/drugTopics/434/json"  
@fields.requested\_uri: "/services/chinesedrugcontent/drugTopics/3393422/json"

Search Queries

Qeury 1: Using double quotes ""  
@fields.requested\_uri: "/services/chinesedrugcontent/drugTopics/3492/json"  
Return: All the documents consisting of exact URL as mentioned in the query

Query 2: Using forward slash //  
@fields.requested\_uri: /services/chinesedrugcontent/drugTopics/3492/json/  
Return: All the documents consisting of terms mentioned in the query like services, chinesedrugcontent etc

Query 3: RegEx  
Form 1: Using ""  
@fields.requested\_uri: "/services/chinesedrugcontent/drugTopics/[0-9]+/json"  
Form 2: Using //  
@fields.requested\_uri: /services/chinesedrugcontent/drugTopics/[0-9]+/json/  
@fields.requested\_uri: /services/chinesedrugcontent/drugTopics//[0-9]+//json/

How to use regex in Kibana? Details given is the following page is not working for some reasons

[https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html)

As per above link, To use reserved keywords as literally, escape it with a preceding backslash or surround it with double quotes. For example:

@ # renders as a literal '@'  
\ # renders as a literal ''  
"[john@smith.com](mailto:john@smith.com)" # renders as 'john@smith.com'

Kibana doesn't allow for regex queries. That guide is for regex queries when sending direct requests to ES. For kibana syntax look for KQL and/or Lucene search syntax.
