问题
I have an RCP application with help enabled on the menus. I am able to successfully bring up the help that I created. However when I type in a search term there are no results returned.
What is required to enable searching my help contents from the Eclipse help engine?
回答1:
The resolution was to update the version number of the plugin with the help content to rebuild the index. I was relying on the .qualifier but that is not sufficient to trigger the index being rebuilt. Once the version was updated all new content was returned on searches.
回答2:
You can check if the issue persists with a small RCP example, like described in this Vogel's tutorial
The required plugins are:
- org.eclipse.help.ui
- org.eclipse.help.webapp
- org.eclipse.equinox.http.jetty
Make sure your help content is well-formed (not like in bug 324854), and that there is no external interaction (like a firewall/anti-virus) with the webapp which will query for you the result of an Help search.
