i made index and inserted a document about phone number like below
```
# curl -XPOST localhost:9200/testindex?pretty -d '{
> "mappings": {
> "document": {
> "properties": {
> "name": {
> "type": "string"
> }
> }
> }
> }
> }'
{
"acknowledged" : true
}
# curl -XPUT localhost:9200/testindex/document/1?pretty -d '{"name": "010-1111-2222"}'
{
"_index" : "testindex",
"_type" : "document",
"_id" : "1",
"_version" : 1,
"_shards" : {
"total" : 1,
"successful" : 1,
"failed" : 0
},
"created" : true
}
```
And, i searched with regular expression. but no found..
what is wrong??
```
# curl -XGET localhost:9200/testindex/document/_search?pretty -d '{
> "query": {
> "query_string": {
> "query": "name:/010-[0-9]{4}-[0-9]{4}/"
> }
> }
> }'
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 10,
"successful" : 10,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : []
}
}
```

Regexes match whole terms. Configure the phone numbers as not\_analzed and
it should work. Also, I try to strip the formatting from.phone numbers and
add the country code. It saves a lot of trouble if you ever have to deal
with numbers with other country codes.

but, if i insert more document like below,
curl -XPUT localhost:9200/testindex/document/1?pretty -d '{"name": "Bob 010-1111-2222"}'
is it also included in result ??
i tested it. but it's not included.
