DataSource Controls :: Linqtosql Contains Based Off Words In Textbox

I am probably doing this wrong but I want to take all words entered in to a text box and return all records that contain any or all of the words. Can any one point me in the right direction?

protected void ldsGvFaqs_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
if (txbSearch.Text.Length > 0)
{
string temp = string.Empty;
string[] words = txbSearch.Text.Split(' ');
int counter = words.Length;
foreach (var word in words)
{
temp += "Tags.Contains('" + word + "')";
counter -= 1;
if (counter > 0)
{
temp += " || ";
}
}
ldsGvFaqs.Where = temp;
}
}

But I get the following error, Character literal must contain exactly one character.
