We have setup a Musical Instrument store on Magento CE 2.3.3 with Elasticsearch 6.8.0.
When doing a search for a generic musical instrument eg piano, guitar, etc. The search results contains the correct products (Products are ordered by 'Relevance'), however the ordering of the products is far from ideal.
For example, it we search for "piano" the top 2 results are a "Ultimate Piano Care Kit" and a "Moth trap for acoustic pianos", then all the pianos on the site are displayed.
Is there a way to alter the "relevance"? I have tried changing the weight of the Product Attribute fields but it doesn't give me the results I want.
