Perhaps you should try some spelling variations:
"drive technologies" » "device technologies", "drive technology", "dome technologies"
"pipe technologies" » "life technologies", "core technologies", "dome technologies"
"edge technologies" » "storage 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: (((("pipe technologies") OR ("drive technologies"))) OR ("edge technologies")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pipe technologies\") OR (\"drive technologies\"))) or (\"edge technologies\"))".
• Removing quotes may allow a broader search: (((( pipe technologies ) OR ( drive technologies ))) or ( edge technologies )).
• Adding a wildcard symbol may retrieve word variants: (((("pipe technologies") OR ("drive technologies"))) or ("edge technologies"))*.
