[solved] Dolphin cannot search "invalid protocol"

[braingateway]

Hi All,

I suddenly get an error "invalid protocol" when I try to "find" with Dolphin.

Can anyone confirm this? Or it just on my system?

How can I make it work again?

Update:
after I installed kfind, I can use kfind directly, but still the dolphin cannot search. This is very annoying.

Thanks!

Hi braingateway,

I confirm this, I actually found this threat searching for a solution myself.
The search tool worked fine under Mint 16, not in Mint 17, both Cinnamon desktops.

Things I tried:

Install kfind (it was already installed)
Install kde-baseapps, kdebase-apps
check that "filenamesearch.protocol" is there under /usr/share/kde4/services/ - it is.

Have you in the meantime found a solution?

Thanks,

David.

When launched form the terminal and trying to search, there is an error about baloosearch:

Code: Select all

dolphin(3478): couldn't create slave: "Não foi possível criar um 'ioslave':
O klauncher disse: Protocolo desconhecido 'baloosearch'.
" 

Which means: the protocol is unkown for 'baloosearch'

Installing the file ´baloo´ gets rid of this error as well as the ´invalid protocol´ on dolphin, but does not search.

Yup. Installing the full baloo app does get rid of the 'protocol' error but still doesn't add real search functionality to Dolphin. No error but no search. I wouldn't exactly call that "Solved". Kfind works fine though.

baloo indexing process is very slow. It will take hours to days. Trying `ps aux|grep baloo` will show the baloo_indexer. Before it is finished, You cannot search.

You should also go to the system setting/desktop searching. It may list the certain folder as non-searchable.

If it still does not work, you can try to turn off the desktop search option:

system settings > desktop search
disable desktop search

Then the dolphin find should work.

This worked for me...
