Magento 2 short search keywords

Question

The Magento 2.1.7 store contains multiple products with names like FA-7

But searching with the exact productname as keyword gives no results. Searching with keyword like SKRF-7 give multiple products as result with productname starting with SKRF.

In Configuration > Catalog > Catalog > Catalog Search, we set the minimal Query Length on 2 characters. Cache cleared, reindexed, but no results.

Anyone have a clue what could be the solution for this problem?

Answer 1

Most probably this is a limitation on the database.
The full text search index has its own minimum word length.
I may be wrong, but I think the default is 4.
Here are more details on how you can change that.
