ColdFusion仅从数据库返回字符串的一部分

I am constructing a search function for our CMS, essentially just creating a cfquery that looks in our database for the given text. When I display the results to the browser I was hoping to have as part of the results a section of the text appear that contains the searched for text as well as like a sentence or two surrounding it. So it would be something like blah blah blah #FORM.searchedstring# blah blah blah. Any ideas on how to only display that specific part of the string?I am constructing a search function for our CMS
