How to find data in mongo?

Question

JavaScript

Let's say I have the name Fermented Fish-Less Fish Sauce | no-cook. Looking for this name. Searches on the first word, on the last. But if I want, for example, to find Fermented Fish, how can I do it?
In JS, I have it like this now

query.title = {
          $regex   : data.title,
          $options : 'i' };

Please tell me how to make it search?
