Perhaps you should try some spelling variations:
"supply can integration series." » "supply can integration theories.", "supply can integrating services.", "supply can integration schemes.", "supply chain integration series.", "supply care integration series.", "supply urban integration series.", "supply case integration series.", "supply a integration series."
"supply furrow irrigation system." » "supply farm irrigation system.", "supply crop irrigation system.", "supply flood irrigation system.", "supply furrow irrigation systems.", "supply furrow irrigation water.", "supply furrow irrigation scheme."

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"supply can integration series.\") OR (\"supply furrow irrigation system.\"))~".
• Removing quotes may allow a broader search: (( supply can integration series. ) OR ( supply furrow irrigation system. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply can integration series.") OR ("supply furrow irrigation system."))*.
