I dont really have the file here but i will try to explain it better.
each company has a button and when you press it the field 'currentCompany' changes to the company you chose.
for example i have yahoo, google and facebook,
google has ten results so when i press the google button it will only show these ten results.
yahoo has zero results so i would expect it to show nothing but instead when i choose its button it shows all the content (in this example both google and facebook).
