Keyword search with negative keywords

I have a simple question about keywords searching in a Go.

I want to search a string using positive and negative keywords

func keyword(itemTitle string, keywords string) bool {
	splits := strings.Split(keywords, ",")
	for _, item := range splits {
		item = strings.TrimSpace(item)

		fmt.Println(strings.ToUpper(itemTitle))
		fmt.Println(strings.ToUpper(item))

		if strings.Contains(item,"-") {
			item = item[1:]
			if strings.Contains(strings.ToUpper(itemTitle), strings.ToUpper(item)) {
				return false
			}
		}

		item = item[1:]
		fmt.Println(strings.ToUpper(item))

		if strings.Contains(strings.ToUpper(itemTitle), strings.ToUpper(item)) {
			return true
		}
	}

	return false
}

heres my searcher method

func TestKeyword(t *testing.T) {
	test1 := "Pokemon Nintendo Switch Cool Thing"
	keywordTest1 := "+pokemon,-nintendo"

	if keyword(test1, keywordTest1) {
		fmt.Println("matched")
	} else {
		fmt.Println("test")
	}

    test2 := "Pokemon Cards Cool"

	if keyword(test2, keywordTest1) {
		fmt.Println("matched")
	} else {
		fmt.Println("test")
	}
}

my test cases
i understand why its not working because +amd is the first in the slice and its ofc going to return true and not test any of the other like -radeon but im just kinda stumped on what todo.

Output given

matched
matched

Expected Output

test
matched

I updated your search function but kept the signature

func keyword(itemTitle string, keywords string) bool {
	a := strings.ToUpper(itemTitle)
	b := strings.ToUpper(keywords)
	keys := strings.Split(strings.Replace(b, "-", " ", -1), ",")
	for _, key := range keys {
		key = strings.TrimSpace(key)
		if strings.Contains(a, key) {
			return true
		}
	}
	return false
}

And updated your test function with a passing test and a failed one to see how it works.

func TestKeyword(t *testing.T) {
	test1 := "Pokemon Nintendo Switch Cool Thing"
	keywordTest1 := "+pokemon,-nintendo"

	if keyword(test1, keywordTest1) {
		t.Log("matched")
	} else {
		t.Fail()
	}

	test2 := "Pokemon Cards Cool"

	if keyword(test2, keywordTest1) {
		t.Log("matched")
	} else {
		t.Fail()
	}
}

Regarding the second test failing with a keyword with + on it, you could pass that through a regex to get only alphanumeric characters, if required.
