How to get similar kind of sku in catalog search result?

Question

I have to create new feature such as did you mean, which is shown in google search engine.

I have multiple similar product sku like G HT2, G HT3 and G HT4. And When I am going to search product with G HT1 (sku). It will show me result as "no such a result found for 'G HT1' ". Its true. Because there are no sku like G HT1

But I need there like "did you mean G HT2, G HT3, G HT4", when I am going search with G HT1.

I hope you will get my point, what I want to do. If any good suggestion, please let me know. It will be great help for me.

Thank you
