This is a bit of a late response to this bug, mojoPortal was recently been acquired by i7MEDIA so we're going through the forums and finding bugs to fix. We've not been able to replicate this bug yet, but there is a way to disable a feature from being included in search results as you requested.
Disabling Feature Search Indexing by GUID
Any feature can be excluded from search indexing by including the feature's guid in the following key's value inside the user.config file.
<add key="SearchableFeatureGuidsToExclude" value="d572f6b4-d0ed-465d-ad60-60433893b401" />
The GUID used in this example is the GUID for the Image Gallery. Enter other feature GUIDS into the same key's value, in a comma separated list, to disable indexing on multiple features.
Note You will probably need to "touch" the web.config after making this change in the user.config (open it, type a space, and save). You will also need to rebuild your site's search index.
Finding a Feature's GUID
If you need to acquire the feature guid of any feature, follow these steps:
- Go to Administration > Advanced Tools > Feature Installation and Configuration.
- Find the feature you'd like to exclude from search results.
- Click the wrench next to that feature's name.
- Copy the GUID from the input labeled "Feature Guid:".
I hope this helps!
