Orion Context Broker Using Match Pattern with number - fiware-orion

Question

For example I have a person like below.
I wan to query person has phoneNumber contains "354".
I will use the query like this: GET /v2/entities?q=phoneNumber~=354.
So is it possible to do the query like this in orion context broker?
As I have seen that the match pattern only support target property as string.
Match pattern: ~=. The value matches a given pattern, expressed as a
regular expression, e.g. color~=ow. For an entity to match, it must
contain the target property (color) and the target property value must
match the string in the right-hand side, 'ow' in this example (brown
and yellow would match, black and white would not). This operation is
only valid for target properties of type string.

{
"name": "phoneNumber",

"value": "0102354678"
}
]
}
Many thanks.

Answer 1

It works as you said.
For instance, using Orion 2.2.0 with an empty database in localhost:1026, creating an entity like the one you propose (but using NGSIv2 endpoint, as NGSIv1 is a deprecated API):
$ curl localhost:1026/v2/entities -H 'content-type: application/json' -d #- <<EOF
{
"type": "Person",
"id": "1",
"phoneNumber": {
"type": "string",
"value": "0102354678"
}
}
EOF
Then, you can do a query with "354" pattern and you will get the entity:
$ curl -s -S 'localhost:1026/v2/entities?q=phoneNumber~=354' | python -mjson.tool
[
{
"id": "1",
"phoneNumber": {
"metadata": {},
"type": "string",
"value": "0102354678"
},
"type": "Person"
}
]
On the contrary, if you do a query for a non-matching pattern (such as "999") you will not get any entity:
$ curl -s -S 'localhost:1026/v2/entities?q=phoneNumber~=999' | python -mjson.tool
