Watir selecting from a dynamically built search list - unit-testing

Question

I am trying to select from a list of li elements that are dynamically aggregated based on search text as keys are entered. The list consistently comes up and some of the time the function correctly allows me to click on the list item and proceed. Other times it times out, early or late I can't tell. I have used sleep statements, inserted key presses, and other methods to get around this without any more success than this statement. Any ideas?
using Watir-classic
this is my seed text for my search function *
ie.text_field(:id, 'school_name').set "linc"
it returns with a list of schools that includes LINCOLN ADAMS ELEMENTARY *
ie.wait_until {ie.text.include? "ADAMS"}
ie.ul(:class, 'searchResults').li(:text => /ADAMS/).click
code without my comments in it
ie.text_field(:id, 'school_name').set "linc"
ie.wait_until {ie.text.include? "ADAMS"}
ie.ul(:class, 'searchResults').li(:text => /ADAMS/).click
puts "school selected"
