Search Filter

Here is my site:

Here is an example result?

What is ten plus ten?

When somebody enters 'ten plus ten' result is returned?
When somebody enters 'What is plus ten' nothing is returned?

How can I make it so that you can enter a query that contains words in any
part of the result.

Thank you.

Do you really expect us to be able to answer this? You have not told us
anything about what the result page is doing? What kind of logic is your query
engine using? Your example query or 'ten plus ten' doesn't return anything. Are
you asking us how to create a search engine?
