We are using ElasticSearch 7.
STEP #1 : we type the first 3 characters of a SKU in the search engine, we get many product suggestions
STEP #2 :we type 4 characters of a SKU in the search engine it says “Sorry, nothing has been found for …
In our test, we only use SKUs related to online products, products that Elasticsearch was suggesting in step #1
Any suggestions?
Thank you for your guidance
