Search email addresses in ElasticSearch by regexp -

how can search in elastic regexp find email addresses?

i try that:

{   "query": {     "regexp": {       "data": {         "value": "[\\w\\'\\.\\_\\+\\-]+@[\\w]+[\\w\\-\\.]*\\.[\\w]+",         "flags": "all"       }     }   } } 

but nothing.

there https://www.elastic.co/guide/en/elasticsearch/reference/5.2/query-dsl-regexp-query.html written simbol @ means symbol , therefore should escaped.

therefore try that:

{       "query": {         "regexp": {           "data": {             "value": "\\@",             "flags": "all"           }         }       }     } 

and that:

{           "query": {             "regexp": {               "data": {                 "value": "\\@",                 "flags": "all"               }             }           }         } 

but nothing again.

any thoughts?

update use elastic search of 5.2 version on ubuntu ubuntu 16.04.2 lts.

data samples:

curl -xpost 'localhost:9200/my_index/index_type/_bulk?pretty' -h 'content-type: application/json' -d' {"index":{"_id":"1"}} {"data":"some text text text text admin@company.comsome text text text "} {"index":{"_id":"2"}} {"data":"some text text hr@company.comsome text text "} {"index":{"_id":"3"}} {"data":"some text text webmaster@company.comsome text text "} 

and searching query:

curl -xget 'localhost:9200/my_index/index_type/_search?pretty' -h 'content-type: application/json' -d' {    "query": {        "regexp": {           "data": {             "value": "\\@",             "flags": "all"           }        }    } } ' 

use "[a-za-z]+@[a-za-z]+.[a-za-z]+" regexp find email addresses. run following query find email address

get /company/employee/_search {    "query": {        "regexp": {           "data": {             "value": "[a-za-z]+@[a-za-z]+.[a-za-z]+",             "flags": "all"           }        }    } } 

here company index, employee type , data field name, insert following data check query works:

post /company/employee/_bulk {"index":{"_id":"1"}} {"data":"admin@company.com"} {"index":{"_id":"2"}} {"data":"hr@company.com"} {"index":{"_id":"3"}} {"data":"webmaster@company.com"} {"index":{"_id":"4"}} {"data":"abc@company.com"} {"index":{"_id":"5"}} {"data":"ahmed@company.com"} {"index":{"_id":"6"}} {"data":"md@company.com"} {"index":{"_id":"7"}} {"data":"boss@company.com"} {"index":{"_id":"8"}} {"data":"amd@company.com"} {"index":{"_id":"9"}} {"data":"ad@company.com"} {"index":{"_id":"10"}} {"data":"ed@company.com"} {"index":{"_id":"11"}} {"data":"etc@company.com"} {"index":{"_id":"12"}}  {"data":"f23f23f23f23f23 d32d23d32d d32d2 3d 23"}  {"index":{"_id":"13"}}  {"data":"d23d32 d32d23d32 etc@company.com d3d23d23"}
