I have a textbox that takes free text as input for a search and I have a LINQ query that I want to extend with this type of search.

The input could be something like "big blue car" and that should result in a query that searches for titles that contain all these words.

There is also an option to switch to "any word" instead of "all words".

What is the best/easiest way to add this to my LINQ query?

The query now looks like

from b in books
where b
.InStore == true && b.Price > 10 && title.Contains()...at this point i want to add the text search.
select b

And i think i have to do something like this:

var searchTerms = input.Split(' ');
from b in books
where b
.InStore == true && b.Price > 10
&& (searchTerms.All(x => b.Title.Contains(x)))
select b

But i keep getting this error : Must specify parameter on right side of operation.
