[lucy-issues] [jira] [Commented] (LUCY-199) Highlighting/excerpt on URLs
[ https://issues.apache.org/jira/browse/LUCY-199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13178019#comment-13178019 ]
Henry commented on LUCY-199:
----------------------------
I have attached a test case for this issue as requested by Nick.
To use:
mkdir test
cd test
tar zxf hltest1.tgz
./runme # to create the test index
To show incorrect highlighting (ie, no highlighting at all) when using 60 char length for excerpt (two hits):
% ./search mweb
…
……
Another:
./search adsl
…
More:
./search news24.com
…
…
Finally:
./search iol.co.za
…
If you comment out the length in ./search:
- excerpt_length => 60,
+ #excerpt_length => 60,
...and rerun the ./search tests, you'll get the expected highlighting, but obviously with an undesirable length.

> Content which is short than 60, returns the highlighted excerpt as expected.
