Shopify Size Filter Not Working

I am using Admin Graph QL to filter the products by title , size and color. I prepared the following query.

query MyQuery {
  products(query: "(title:*Puma*) AND (size:14)", first: 10) {
    edges {
      node {
        id
        productType
        tags
        title
        totalVariants
        vendor
        images(first: 3) {
          edges {
            node {
              src
              url
            }
          }
        }
      }
    }
  }
}

Actually there is 2 Products with PUMA title but the available size is 11 and 12 only. If i search for 14 size as well it is giving results of PUMA title. How can i get exact products which is having title and correct size as well?

Hi @dineshprima

At this time, size is not a valid product filter parameter. You can find the list of supported product query filter parameters here in Admin API.
