Redaction of multiple words/patterns using Adobe Acrobat 9 question

This is my question.
How can I use an Adobe Acrobat 9 advanced redaction search of words that allows me to deselect from the search box (as opposed to the document page)specific appearances of the same word ie: directly from the list of word occurrences first found.
When searching for patterns the search box asks me to check the instances I want to select for redaction, and I can select all, then deselect some. The search box for words does not to my knowledge allow this. All the instances are checked from the get go. What am I missing.
