Question

string1: How
string2: How Are you ?

What i want to do is select all records from the database by checking string2 against string1 and selecting any record which have either “How” or “Are” or “you”.

 pager1.ItemCount = appliedQuery.Where(q => q.string1.Contains(string2)).count();

PlEASE NOTE: String1 is just one word and I just want to get all records in the db with any occurance of any word in string2.

I understand that string2 needs to split, however after the split how do i use it in the linq query statement to fetch the records?

Thanks in advance

Check out how I constructed my linq query. I hope this helps.
Just try to copy and paste the code in your console app to see the result.

class Program
{
    static void Main(string[] args)
    {
        // List of strings that you may consider it from your 
        /// database which is String1
        List<string> lstStrings = new List<string>();
        lstStrings.Add("twenty one");
        lstStrings.Add("twenty two");
        lstStrings.Add("twenty three");
        lstStrings.Add("twenty four");

        // The string to compare to which is your String2
        string strString = "one two four";

        // Splitting the strings to be compared
        string[] strArray = strString.Split(' '); 

        // The linq that helps you query the data exactly as what you wanted
        var result = (from string A in lstStrings
                               from string B in strArray
                               where A.Contains(B)
                               select A).Distinct();

        // Count result
        Console.WriteLine(result.Count());

        // Individual values
        foreach (string str in result)
        {
            Console.WriteLine(str);
        }

        Console.ReadLine();
    } 
}
