Address Book Ignore Words

I have a problem with adding words to the Ignore Words list for Address Book. They appear to add okay but are not ignored in Word Search. I have tried adding them to system codes 00, 01 and 55 but to no avail. I am using the Ignore function shown as a exit bar option from Address Book Word Search. What am I doing wrong?

Did you rebuild the Word search?

Thanks for you response. No I haven't run the Word Build again (R01BDWRD). Will this sort out the Ignore Word issue? As far as I can make out the Word Build didn't ignore any words at all. I thought it just ignored the words at the Search stage. I'm obviously doing something wrong or I need to configure something.
