This one is quite difficult to reproduce.

Sometime, after a creation/modification, the search result does not return all org-units, and the graphical view display more than the search (but not always all that have been created)

I got it twice :

1) when I got issue UD-118

After that, 2 units were not displayed anymore in the search result, and even less in the graph.

(6/8 in search, 4/8 in graph)

(and after a reboot, New 2 and 3 were not displayed in search anymore, New 1 was displayed with language = en, and the graph did not change)

The other time, I had an error in search because solr was not launched so I restarted everything (tomcat & solr) and got 3 items in search and 8 in the graph

(same data as previous screenshot but there were no relations between New 1, 2, 3 and 4)
