Search any part of word in any column - ruby-on-rails-4

Question

I'm trying to search full_name, email or phone
For example
if i start input "+16", it should display all users with phone numbers start or contains "+16". The same with full name and email
My ES config is:
{
"users" : {
"mappings" : {
"user" : {
"properties" : {
"full_name" : {
"analyzer" : "trigrams",
"include_in_all" : true,
"type" : "string"
},
"phone" : {
"type" : "string",
"analyzer" : "trigrams",
"include_in_all" : true
},
"email" : {
"analyzer" : "trigrams",
"include_in_all" : true,
"type" : "string"
}
},
"dynamic" : "false"
}
},
"settings" : {
"index" : {
"creation_date" : "1472720529392",
"number_of_shards" : "5",
"version" : {
"created" : "2030599"
},
"uuid" : "p9nOhiJ3TLafe6WzwXC5Tg",
"analysis" : {
"analyzer" : {
"trigrams" : {
"filter" : [
"lowercase"
],
"type" : "custom",
"tokenizer" : "my_ngram_tokenizer"
}
},
"tokenizer" : {
"my_ngram_tokenizer" : {
"type" : "nGram",
"max_gram" : "12",
"min_gram" : "2"
}
}
},
"number_of_replicas" : "1"
}
},
"aliases" : {},
"warmers" : {}
}
}
Searching for name 'Robert' by part of name
curl -XGET 'localhost:9200/users/_search?pretty' -d'
{
"query": {
"match": {
"_all": "rob"
}
}
}'
doesn't give expected result, only using full name.

Answer 1

Since your analyzer is set on the fields full_name, phone and email, you should not use the _all field but enumerate those fields in your multi_match query, like this:
curl -XGET 'localhost:9200/users/_search?pretty' -d'{
"query": {
"multi_match": {
"query": "this is a test",
"fields": [
"full_name",
"phone",
"email"
]
}
}
}'
