Hi Thomas, Remember, we also publish a SPARQL Endpoint for Wikdata access [1]. You can repeat your tests there too. Example (note that the retry loop indicates resources limits of this particular instance setup): Search on "Paris" http://wikidata.demo.openlinksw.com/fct/facet.vsp?qxml=%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22UTF-8%22%20%3F%3E%3Cquery%20inference%3D%22%22%20same-as%3D%22%22%20view3%3D%22%22%20s-term%3D%22%22%20c-term%3D%22%22%3E%3Ctext%3EParis%3C%2Ftext%3E%3Cview%20type%3D%22text-d%22%20limit%3D%2220%22%20offset%3D%22%22%20%2F%3E%3C%2Fquery%3E <http://lod.openlinksw.com/fct/facet.vsp?qxml=%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22UTF-8%22%20%3F%3E%3Cquery%20inference%3D%22%22%20same-as%3D%22%22%20view3%3D%22%22%20s-term%3D%22%22%20c-term%3D%22%22%3E%3Ctext%3EParis%3C%2Ftext%3E%3Cview%20type%3D%22text-d%22%20limit%3D%2220%22%20offset%3D%22%22%20%2F%3E%3C%2Fquery%3E> Config: OpenLink Virtuoso version 08.03.3315 as of Sep 4 2019, on Linux (x86_64-generic-linux-glibc25), Single-Server Edition (378 GB total memory) Same thing using the LOD Cloud cache instance, where data is a little out of date also: http://lod.openlinksw.com/fct/facet.vsp?qxml=%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22UTF-8%22%20%3F%3E%3Cquery%20inference%3D%22%22%20same-as%3D%22%22%20view3%3D%22%22%20s-term%3D%22%22%20c-term%3D%22%22%3E%3Ctext%3EParis%3C%2Ftext%3E%3Cview%20type%3D%22text-d%22%20limit%3D%2220%22%20offset%3D%22%22%20%2F%3E%3C%2Fquery%3E Config: OpenLink Virtuoso version 07.20.3224 as of Dec 19 2017, on Linux (i686-generic-linux-glibc212-64), Cluster Edition (4 server processes, 756 GB total memory) Links [1] http://wikidata.demo.openlinksw.com/fct [2] http://wikidata.demo.openlinksw.com/sparql -- Regards, Kingsley Idehen Founder & CEO OpenLink Software Home Page: http://www.openlinksw.com Community Support: https://community.openlinksw.com Weblogs (Blogs): Company Blog: https://medium.com/openlink-software-blog Virtuoso Blog: https://medium.com/virtuoso-blog Data Access Drivers Blog: https://medium.com/openlink-odbc-jdbc-ado-net-data-access-drivers Personal Weblogs (Blogs): Medium Blog: https://medium.com/@kidehen Legacy Blogs: http://www.openlinksw.com/blog/~kidehen/ http://kidehen.blogspot.com Profile Pages: Pinterest: https://www.pinterest.com/kidehen/ Quora: https://www.quora.com/profile/Kingsley-Uyi-Idehen Twitter: https://twitter.com/kidehen Google+: https://plus.google.com/+KingsleyIdehen/about LinkedIn: http://www.linkedin.com/in/kidehen Web Identities (WebID): Personal: http://kingsley.idehen.net/public_home/kidehen/profile.ttl#i : http://id.myopenlink.net/DAV/home/KingsleyUyiIdehen/Public/kingsley.ttl#this
