+  RECORD WITH pname=val` returns all current and old versions of records where
+  `pname=val`. For further information, examples and limitations see the wiki
+  page on [CQL](https://gitlab.com/caosdb/caosdb/-/wikis/manuals/CQL/CaosDB%20Query%20Language)

   space separated list as values. The server looks for scripts in all
   directories in the order or the list and uses the first matching file.
