+RULES
+
+Single arguments:
+    - arg:value translates into arg='value' in query
+    - quotes are cleared
+    - if value contains spaces, punctuation or anything else it has to be put in quotes
+    - file is source_reference (original file name)
+    - language, version, reference
+
+Multiple arguments:
+    - arg:xxx works the same way
+    - arg:(xxx,yyy) ORs both (do not put space after comma)
+    - arg:all translates into empty tuple, which implies all available values
+    - state (simulation_state), type (portal_type)
+
+Everything else is treated as SearchableText
