Aws Api-Gateway set cache to specific GET method?

I build an API for web application, everything works just fine , but i want to set “cache” for specific GET method.
It seems that i cant find any info regarding this issue in the documantation.
how do i set the cache with query string parameters?

      path: item/get
      method: get
      cors: true
      integration: lambda
name: ${self:service}-${self:provider.stage}-getItems
