magento2.4 – Catalog Search result Wrong Result Magento 2

I am facing issue in the search result. I have installed Magento 2.4.0 and using Elasticsearch 7.0.
When i search for h397 it gives me 4 product count and if i search for h397-4 it gives me 1868 product count. Might Magento consider it as a separate value like h397 and 4. So how can i fix this issue?

Please check attached screenshot for more clarification.

Is there any solution?
