Elastic terms query with emails not working - elasticsearch

Question

I want to pass a list of emails in Elastic Search Query, So I tried below query to achieve that, but didn't get any result.
{
"query": {
"terms": {
"email": [ "andrew#gmail.com", "michel#gmail.com" ]
}
}
}
When I used id instead of emails, that worked !
{
"query": {
"terms": {
"id": [ 43, 67 ]
}
}
}
Could you please explain what's wrong with my email query and how make it works

Answer 1

If you want to recognize email addresses as single tokens you should use uax_url_email tokenizer.
UAX URL Email Tokenizer
A working example:
Mappings
PUT my_index
{
"settings": {
"analysis": {
"analyzer": {
"my_email_analyzer": {
"type": "custom",
"tokenizer": "my_tokenizer",
"filter": ["lowercase", "stop"]
}
},
"tokenizer": {
"my_tokenizer":{
"type": "uax_url_email"
}
}
}
},
"mappings": {
"properties": {
"email": {
"type": "text",
"analyzer": "my_email_analyzer",
"search_analyzer": "my_email_analyzer",
"fields": {
"keyword":{
"type":"keyword"
}
}
}
}
}
}
POST few documents
POST my_index/_doc/1
{
"email":"andrew#gmail.com"
}
POST my_index/_doc/2
{
"email":"michel#gmail.com"
}
Search Query
GET my_index/_search
{
"query": {
"multi_match": {
"query": "andrew#gmail.com michel#gmail.com",
"fields": ["email"]
}
}
}
Results
"hits" : {
"total" : {
"value" : 2,
"relation" : "eq"
},
"max_score" : 0.6931472,
"hits" : [
{
"_index" : "my_index",
"_type" : "_doc",
"_id" : "1",
"_score" : 0.6931472,
"_source" : {
"email" : "andrew#gmail.com"
}
},
{
"_index" : "my_index",
"_type" : "_doc",
"_id" : "2",
"_score" : 0.6931472,
"_source" : {
"email" : "michel#gmail.com"
}
}
]
}
Another option is to use keyword type.
Search Query
GET my_index/_search
{
"query": {
"terms": {
"email.keyword": [
"andrew#gmail.com",
"michel#gmail.com"
]
}
}
}
In my opinion using the uax_url_email tokenizer is a better solution.
Hope this helps
