Apple 1 1 SMS search can't find keywords?

1 First, open the "Info" application of iPhone, and find the SMS content to be deleted. Then click the "Edit" button in the upper right corner.

Next, please check the message you want to delete, and then click the red "Delete" button below.

3 Then click the "Delete Information" button to confirm the deletion.

Now let's go back to the home screen and slide our finger to the right on the home screen until the "one-click search" interface appears.

Next, we enter keywords in the "search box". I enter the keyword "Test" here to delete the previous SMS content, and then click the "Search" button in the lower right corner. The result will actually show the text messages we have deleted before.
