Nick Wellnhofer updated LUCY-199:
---------------------------------
Attachment: LUCY-199-quickfix.patch
Here is the simplest partial fix I could come up with. I'm not really happy
with it because it can produce excerpts that don't contain the search term. For
example, if you set excerpt_length to 40 in Henry's test case, you get the
following result:
$ ./search statue
www.iol.co.za/tonight/books/what-the-di…
The full URL is
www.iol.co.za/tonight/books/what-the-dickens-gets-a-statue-1.1130220 and it
gets truncated before the term "statue". But the patch is certainly an
improvement.
