my phrase_prefix query does not work for numeric values - elasticsearch

Question

my query is pretty simple, it looks like this:
{
"query": {
"bool": {
"should": [
{
"multi_match": {
"query": "something_to_search",
"type": "phrase_prefix",
"fields": [
"name",
"id"
...
],
"lenient": true
}
}
],
"minimum_should_match": 1,
"boost": 1.0
}
}
}
name is text value and id is numeric value, if I search for "Jo" I will get people who's names starts with "Jo", but if I search for "123" I wont get people who's id's starts with "123", but if I search for the exact id I will get a result.
can someone please tell me how can I get also prefix queries on numeric?
my mappings:
{
"people_db": {
"mappings": {
"person": {
"properties": {
"address": {
"properties": {
"city": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"street": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"streetNumber": {
"type": "long"
},
"zipCode": {
"type": "long"
}
}
},
"country": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"id": {
"type": "long"
}
}
}
}
}
}
