So my customers tend to be more so individuals who are not computer literate and often make errors when searching for our products. What is the best way to work out what they're trying to search for and serve it to them? Preferably for free. I'm not asking for module recommendations necessarily if there's code in Magento 2 that I can go in and edit to serve this purpose, that would be most ideal. What is the best way to get this functionality implemented in to my search bar?
EDIT: I'm gonna go with Piyush's replies in the comments, i'm not even allowed to use a third party extension I asked my boss. Instead i'm going to code it based on the github links Piyush left me in reply to this question.
