[CHEMiST]

In your includes/config.php the variables PHPDIG_EXCLUDE_COMMENT and PHPDIG_INCLUDE_COMMENT are define by default:

define('PHPDIG_EXCLUDE_COMMENT','<!-- phpdigExclude -->');  
define('PHPDIG_INCLUDE_COMMENT','<!-- phpdigInclude -->');

Use these tags to include and exclude html content from being indexed on their own lines:

<!-- phpdigInclude -->
content I want included for index
<!-- phpdigInclude -->

<!-- phpdigExclude -->
content I want excluded from index
<!-- phpdigExclude -->

Pages that do not have these tags are indexed implicitly. If you cannot get this working with v.1.8.9RC 1 try reverting back to the v.1.8.8 stable release.
