Currently the NumericFilter allows for searching for numeric-string or numeric-string[]:

/api/entity?numericValue=5
/api/entity?numericValue[]=5&numericValue[]=6

This PR adds the support for comma-separated numeric-values:

/api/entity?numericValue=5,6

Which allows for much shorter urls when searching on multiple numeric values and if I understand the specification correctly this is a valid format. A snipper from the documentation:

Query parameters can be primitive values, arrays and objects. OpenAPI 3.0 provides several ways to serialize objects and arrays in the query string.

Arrays can be serialized as:

form – /products?color=blue,green,red or /products?color=blue&color=green, depending on the explode keyword

I'm a bit lost how to test the NumericFilter. Looking at src/Doctrine/Orm, running composer install in this directory and then starting the test will use the api-platform/core classes from vendor instead of using src/Doctrine/Orm/Filter/NumericFilter.php

If I run the test with phpunit from the root of the project, the test crashes as the Doctrine driver can't be found.

I could use some tips how to solve this.

I'm really not sure we want to add this to our codebase as all our filters work by having this syntax:

/api/entity?numericValue[]=5&numericValue[]=6

With the QueryParameter we tried to improve the tools users can use to re-use filters but in their own way, it should be fairly easy to add (and document) this in your own codebase.
