Perhaps you should try some spelling variations:
"plant technologies" » "plasma technologies", "smart technologies", "agent technologies"
"pnt technologies" » "iot technologies", "art technologies", "net technologies"
"ict technologies" » "iot technologies", "recent technologies", "smart technologies"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("plant technologies") OR ((("pnt technologies") OR ("ict technologies")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"plant technologies\") or (((\"pnt technologies\") OR (\"ict technologies\"))))".
• Removing quotes may allow a broader search: (( plant technologies ) or ((( pnt technologies ) OR ( ict technologies )))).
• Adding a wildcard symbol may retrieve word variants: (("plant technologies") or ((("pnt technologies") OR ("ict technologies"))))*.
