Filter USER-defined words

What Node can I use to filter the User-defined words? 


for example:

The String "Mr. Smith"  wil be after "BoW":





What can I use to filter the Mr out?

Thank you very very much!!!!!

Hi Shony,

you might want to take a look at the stop word filter-node. You can use a custom stop word filter list to get rid of user defined words (see node-configuration).
You need to provide a list of terms with one termn per line terms (multiwords are also possible). E.g.

Prof. Dr.

To assure a correct charset I'd recommend to use UTF-8 encoding.
