Creating a Search for information in an XML file

[KiKaL]

I'm trying to figure out the best way to create a search box that searches an XML document and returns the results. So far I know how to do a search that returns exact matches but I want to make it so if someone typed in say "Manager" it would return results that Also had "Sales Manager" or "Account Manager".

Currently I have

var  authorList:XMLList  =  xmlData.job.(title  == citySearch.text); 

Which only works with exact results. What is the best way to get around this? Do I just need to bring in everything from the XML file and then compare it using .search()?
