I'm doing de Titanic Competition of Kaggle and I trying to check if the attribute name has string like Mr, Mrs, Miss,... But I don't know which operator is the adequate in this situacion.
The approach you can take depends on whether you want to filter examples, or end up with some further calculations. For the former, you could use Filter Examples using the condition "contains", and also have multiple checks where an example only needs to match one. I've provided a short example of this below. You could also use Generate Attributes and the contains() function, which would give True/False depending on whether a nominal attribute contains the search string.

Hope this helps.
