How to return a string with 5 previous words and 5 after words

P: n/a
hello friends !

i have a database full of articles. I want to search that database with
keywords.
i expect this database to send me back a list of articles containing the
search string(s).
i would like to display the result like google does: the searchstring
highlighted within its context sentence (about 20 characters before, and 20
characters after the searchstring).

I'm wondering how to return the contextual sentence.

any idea?
