Tweak the WP Query search

I am having a hard time trying to find a way to tweak the search option on my wordpress website.
For example: I have products with the word electronic and monitor in the title, however when people search with the word electronics or monitors (plural) it won’t pull the results of all the products containing either the title electronic or monitor and I guess that’s not good. Probably I’m loosing potential buyers.
Any idea how to tweak that just for these 2 words?

electronics to display all the products containing the word electronic
and the same for monitors to display all the products containing monitor in the title. Something like to match the keyword electronics to electronic and same for monitors to monitor.
