Solr Search module - error when configuring the search page

Hi everyone,

I am pretty new to Omeka and it’s the first time I’ve tried to use Solr on it, so I’m sorry if the answer is obvious. I use the v. 2.0.2 of Omeka-S and I’m trying to use the Solr module (v. 0.5.0) and the Search module (v. 0.5.0) . I have also install the Jquery-UI module which is needed.

I have follow the instructions from the github page :

_I installed the Solr instance
_ I have configured the Solr module (host, port, etc.)
_I have created a new index in the search module and I managed to launch the “reindex button”.
_I have created a new page in the search module but after filling in the first page (with name, path, index and form) this error appears on the second page :

Notice: Undefined variable: facetFields in /sites/rita/www/web_main/modules/Solr/src/Adapter.php on line 134
Warning: count(): Parameter must be an array or an object that implements Countable in /sites/rita/www/web_main/modules/Search/src/Form/Admin/SearchPageConfigureForm.php on line 69
Warning: Invalid argument supplied for foreach() in /sites/rita/www/web_main/modules/Search/src/Form/Admin/SearchPageConfigureForm.php on line 72

And I think I don’t have all the option available because I cannot enable or disable facet and sort fields.

Do you know what the problem may be ?

Thanks a lot for your help.

The modules are not up to date. Try my versions, that are fully working in Omeka S 2.1 (example : and .

Hi Daniel,

Thanks for your answer, I tried your versions of the modules and indeed it worked perfectly well!

Thanks a lot!


Unfortunatelly, I have others problems with the module … When I’m lauching the reindexation on the solr module, the log show me this error :

It happens to about half of my items, but the indexation managed to finish.

And I have another problem with the form, when I try to put it on a page I have this error :

Also when I’m reaching the page with the search bar and I’m lauching a search, there is no result, but I assume this is related to a problem that I mentionned before.

Thanks a lot for your help,


Apparently, you have a field that is not in the mapping. Did you removed it during indexation?

For the other point, it’s a bug (that doesn’t appear with another module I use). It will be fixed Monday with the next release.
And this is still an experimental feature.

Thanks a lot for your answer @Daniel_KM, I will wait the next release and keep you inform.

About the problem with the indexation, indeed the problem came form the mapping, I checked it and I replaced the Solr field which is attached to dcterms_temporal by another and then the indexation worked for all my items.

Thanks again for your help and your hard work!


I pushed a new release of module Search (and Solr if needed), with new features, in particular the possibility to use it as a block.
