I have installed blog assets but when I am searching for a Blog_Asset in contributor it displays no results whereas I have checked the entries in Blog_Asset table it contains 28 entries. What could be issue ? Is the issue related to resultsetcashe ? I have invalidated the resultsetcache but no change.
Try rebuilding the index for the FW_BlogParent and FW_BlogAsset asset types from the Admin tab -> Search -> Configure Global Search. Select Re-index, then select those two asset types, then click Ok.
Wait a minute or so, then try searching in the contibutor UI again.
If you're referring to a different kind of Blog asset you can try the same thing for your specific Blog asset type.
