is it possible to have two keys with the same name (but different values)

is data :

{

month:'june',

month:'july'

}

is not how would I go about makeing a get request where multiple values have the same name as per the bellow example from here  https://lucidworks.com/blog/2009/09/02/faceted-search-with-solr/

This is a sample GET request where multiple fields are called facet.query so that multiple values can be passed

&facet=true
   &facet.query=price:[* TO 100]
   &facet.query=price:[100 TO 200]
   &facet.query=[price:200 TO 300]
   &facet.query=price:[300 TO 400]
   &facet.query=[price:400 TO 500]
   &facet.query=price:[500 TO *]
