@butonic What do you think?

[butonic]

Maybe a duplicate of owncloud-archive/search_lucene#17. I am preparing a new version of search lucene. The stable7 branch has the ocsid already merged and I think @icewind1991 and have been polishing it for quite some time now. I only need to make sure it works with the latest patches to the session and user api in core/stable7. I then plan on releasing the new version via the appstore as soon as I get final testing done.

[MTRichards]

Unable to reproduce on Debian variant with SQLite and oC 7.0.0 RC3. Running PHP 5.4.

[NightWorx]

adding a simple "x" in provider.php#5 (/lib/private/search/provider.php) solved the problem for me.
Of course: this is a weird & dirty fix, but hey, it works! ;)
old line #5: "abstract class OC_Search_Provider {"
fixed line #5: "abstract class OC_Search_Providerx {"

According to other posts, this is a conflict betwen OC & Zend
however, this should be fixed.

FreeBSD 9.2-RELEASE-p10, PHP 5.4.30, MySQL 5.5.37

[butonic]

I am currently moving the codebase to the composer autoloader. That should resolve class loading as @DeepDiver1975 already pointed out. The fix you posted will break ALL search providers, and will give you class not found exceptions whenever using the search. No matter if search_lucene is involved or not, because all search results are derived from OC_Search_Provider.

I'll post an update when a version with composer is available.

[NightWorx]

true...true...
but in My situation, I prefer to have a working login instead of a working search engine (although its still working...?).
However: the described fix was never meant to be a proper solution. To me it was just a dirty workaround that allowed me to still log in - nothing more.

[marfig2005]

Hi, I have same problem, I had OC6 where search was working and today I upgraded to OC7 and search stopped work

[merlin2004]

The same problem here after upgrade to OC 7 stable.

[TechCare-Aus]

Same problem here

[butonic]

@SilFoiera @marfig2005 @merlin2004 @sjswarts85 How exactly did you update?

I am asking because the release tarball does not contain a /lib/private/search/provider.php. Could it be that you did not move away the old owncloud code as described in http://doc.owncloud.org/server/7.0/admin_manual/maintenance/update.html#upgrading-the-owncloud-server:

@DeepDiver1975 @karlitschek now that I am reading the docs, simply overwriting the old code and not extracting into an empty directory is not supported as an upgrade path. The documentation is clearly wrong there. Otherwise loft over classes, as in this case will be picked up twice by the autoloader.

For anyone who has run into this problem: simply delete /lib/private/search/provider.php It is a leftover from the old owncloud installation.

For completeness sake: I misinterpreted this issue with loading zend classes because they might have been installed system wide.

[TechCare-Aus]

@butonic G'day mate, I cheat a little and maybe it is the packager's issue. I use cPanel hosting with Installatron. When I updated through the Web interface I was greeted with that error.

Googling it led me here, so if you think its a problem with the package maintainer I will contact them directly and post back.

[oparoz]

@sjswarts85 Please open a ticket with Installatron so that they update their upgrade procedure :)

[TechCare-Aus]

@oparoz ok will do

[merlin2004]

@butonic:
I also removed the old /lib/private/search/result.php.
Otherwise you will get this error:
"Cannot redeclare class OC_Search_Result at ....../private/search/result.php"

[butonic]

I updated the documentation accordingly. Have a look at owncloud-archive/documentation#464 and give a quick 👍 If you think it makes sense.

[butonic]

The documentation has been fixed accordingly, closing this.

[oparoz]

👍

[enoch85]

@butonic This was a fresh install though...

[butonic]

@enoch85 The release tarball does not contain a /lib/private/search/provider.php. Could you check that you don't have that file? How did you install? With the release tarball or via a distro package?

You can just delete /lib/private/search/provider.php. Although I recommend updating to the latest stable7.

[enoch85]

@butonic No, I don´t have provider.php anymore. But I don´t remember if I took it away manually more than 2 weeks ago.

I always install via package.

Anyway, now I get this instead:

@butonic PING

[FreeMinded]

Removing the two left over files mentioned here did the job for me!
/lib/private/search/result.php
/lib/private/search/provider.php

Thanks!

[butonic]

@enoch85 please stay on topic of the original issue. Encrypted document modification is not supported tells me that an encrypted PDF is used. We have no way of indexing them, but I agree that that should not have the level ERROR. Could you try with search_lucene master and open an issue in that repository if the problem still exists?

[ace02000]

great! Thank you for this solution.
This worked for me.
