i did not understand the question very well, but you can use the string.IndexOf() to get the postion of a word in a paragraph!

C#

string msg = "abcdefghijklm...";
int index = msg.IndexOf("fghi"); // the value is 5 in this case
//if the word dont exsist, you will get an exception so better test if the word exsist before getting the index.

if(msg.IndexOf("fghi") != -1)
{
}
