Magento Search Not working – Only returns results if I search SKU codes

I have a Magento 2.4.3 installed with Elasticsearch 7.9 They are on separate servers (but I don’t believe that is relevant). The reindexing function runs successfully and I can see the index on the elasticsearch:

health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open .geoip_databases Pe0O24UMQmuLHIVp_H5Jkw 1 0 42 0 40.1mb 40.1mb
yellow open magento2_product_1_v2 LE4DUb_6QhmZ1K_E0oyIgA 1 1 727 0 1008kb 1008kb

But when I search for anything meaningful in the front end using the Luma theme nothing comes up only if I search using SKUs.

Everything seems to be running just fine, so I just don’t know where to look. I have tried all of the usual suggestions on here.
