Linq search for any of words in term

Question

I have a requirement to search an IQueryable list for the words in a search term.

Currently I have this working but it is for an exact match.

list.Where(x => x.MyList.Any(y => y.ToSearch.ToLower().Contains(searchTerm.ToLower())));

What I need is if someone searched for "search term" results should be:

"terms of search" "another search term"

I am not sure the best way to go about this in linq can anyone help please?

Answer 1

//split the search terms by space
var searchWords = searchTerm.ToLower().Split( " ".ToCharArray(), 
                          StringSplitOptions.RemoveEmptyEntries);

//check if any of those search terms is present
list.Where(x => x.MyList.Any(y => 
        searchWords.All(sw=>y.ToSearch.ToLower().Contains(sw))));
