When you display each hit, first scan the text and build an array 
containing the positions of each newline.  Then use the highlighter (in 
contrib/highlighter) to find fragments:

   TextFragment[] frags = highlighter.getBestTextFragments(...);

Finally, display these fragments as complete lines by searching the 
array of line starts for the first fragment's start position to find the 
start line, and the last fragment's end position to find the last line.
