[lucy-issues] [jira] [Resolved] (LUCY-199) Highlighting/excerpt on URLs

["Nick Wellnhofer (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCY-199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nick Wellnhofer resolved LUCY-199.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 0.4.0

After rewriting the Highlighter code to use string iterators, the test case produces:

{noformat}
$ ./search statue
&#8230; ckens-gets-a-<strong>statue</strong>-1.1130220
$ ./search dickens
&#8230; oks/what-the-<strong>dickens</strong>-gets-a-statue-1.
{noformat}

This could be improved by breaking at non-alphabetic characters, but I think it's good enough to resolve this issue.

(Note that the test case file 'runme' has to be changed to use a FullTextType with 'highlightable => 1'.)
