predicates without quoting strings

[flashpixx]

Hello,

I'm using the call predicate.TextContains with that call .Has("lastName", predicate.TextContains("t") and this creates an error, because the passed variable content will not be quoted, I must replace it with .Has("lastName", predicate.TextContains(""t"")` .

In my opinion the definition of the function seems not be correct:

func TextContains(str string) *Predicate {
	s := "textContains(" + str + ")"
	a := Predicate(s)
	return &a
}

The fixed definition of the first function line should be

s := "textContains(\"" + str + "\")"

Other calls can be create similar issues.

Thx
