Words & long text fields

[Spore]

Dear all,

I am a relatively new user of Filemaker (from the social sciences!) and this question may sound extremely simple, but unfortunately I could not find a solution by my own yet.

Here's the problem:

I have a text field called "Text" with complete law texts. This means that these texts are relatively long (i.e. thousands of characters).

I need to create a field with a dichotomous variable (Yes/No). I would like to get a "Yes" or a "No" in this dichotomous field in case a series of words ("President", "Governor") are present in my "Text" field.

Until now I've been trying with the following calculation without luck:

If ( Text = "President" or "Governor"; "Yes" ; "No" )

However, if I apply the same formula to another text field which comprehends a single word, this calculation works perfectly.

Do you know if this kind of calculation functions work differently depending on the size (i.e. number of characters) of a text field? Do you think that I should use another function instead?

Thank you in advance for your help!

Try:

PatternCount ( Text ; "President" )

or 

PatternCount ( Text ; "Governor" )

This will return 1 if true, 0 if false - which is the best way to set up a Boolean (what you call "dichotomous") value.

Try

Case(

PatternCount(Text; "President"); "Yes";

PatternCount(Text; "Governor"); "Yes";

"No"

)
