如果在文本字符串中至少找到一个特定的匹配文本，我需要使条件为真，例如：
str = "This is some text containing the word tiger."
if string.match(str,"tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
如何检查文本是否在字符串中的某处找到？
解决方法
你可以使用string.match或string.find。我个人自己使用
string.find()。此外，您需要指定if-else语句的结尾。所以，实际的代码将如下：
str = "This is some text containing the word tiger."
if string.match(str,"tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
要么
str = "This is some text containing the word tiger."
if string.find(str,"tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
