Azure cognitive search config issue

Question

I have created an index with 10k items. My search URL looks like this

 https://{mysearchname}.search.windows.net/indexes/{myindexname}/docs?api-version=2021-04-30-Preview&search=28597~&searchMode=any&queryType=full

The result I am expecting is

{
        "@search.score": 42.263885, //This is expected to be higher since the product code matches like 60-80%
        "id": 335946,
        "productCode": "028579",
}

but the one currently being found as a better match is

{
        "@search.score": 42.263885,
        "id": 331128,
        "description": "Grohe 46595",
        "productCode": "028517",
    }

There are a few results it orders above the one I want to match on. but they all have the same search score.

Why is this and how can I fix this?
