How to search more than one options on click on submit through ransack search

i want to search both category and location on click on search(Ransack)

my view

<%= form_tag location_path, :method=>'get' do %> 
<%= select_tag :q, options_from_collection_for_select(Category.all, :id, :name, params[:q]) %>
<%= text_field_tag :q, nil,:placeholder=>"Tell us what you are looking for.." %>
<input type="submit" value="SEARCH" class="btn1 home-search-button" >
<% end %>

This is my view of this form my searchcontroller is

def location
    q = params[:q]
    @key=q
    @property = Property.ransack(location_or_category_name_cont: q).result(distinct: true)
  end

this search searches only location not category,
on executing i am getting like this, 
`url is like this : http://localhost:3000/location?utf8=%E2%9C%93&q=2&q=banglore`

command iam getting on executing ` Here it is searching banglore as category name and location(it should search 'commercial' as category_name(which is under category_id:2) instaed of banglore'

Any help is appreciatable
