How to reproduce

• Create a page "Page A" under a validated page of first level
• Add a content article
• Edit the content with title= "Title A", content= "Lorem ipsum sit amet"
• Validate the content
• Search content by search module with text "lorem"
• Page A is in search result
• Edit the content and change the content with "Quisque quis odio arcu"
• Search content by search module with text "odio"

Behavior

• The page A is NOT in search result
• In lucene index the "excerpt" field is still equals to "Lorem ipsum"

Excepted behavior

• The page A is in search result
• The lucene index is updated with the new content

The same test on a first level page seem to work well.
After shutdown and restart tomcat, the same test on the same content works.
