how to filter my list
and have for example

cb_username NOT NULL

OR

'cb_field'= 'whatever'


i WOULD LIKE TO ASK HOW TO FILTER in advanced option to have one field OR another
thnx

i writed:

'cb_astutorican '= 'show around the city'
or 'cb_astutorican '= 'host for first days'
or 'cb_astutorican '= 'help findig room'
or 'cb_astutorican '= 'help with university documentation'
or 'cb_astutorican '= 'take from the station'
or 'cb_astutorican '= 'show the faculty'


but 0 user shown in my list

it is a multiple check box field

I think you have some bug here

I am guessing that the filter is looking for the ID of the checkbox and not the actual value. Each value in the checkbox should be assigned a field ID of some sort.
