How To filter Complex Table Row

Hi,

I create a Complex Table like this :

ID    |     Property_filter

------------------------------------

1      |    T

2      |    T

3      |    F

4      |    F

5      |    F

6      |    T

In some add/edit screenset, I have to show in a Complex Table Search only the row with Property_filter = "T".

What is the right index structure for my complex Table ?

Thank you in advance.
