Perhaps you should try some spelling variations:
"phase transactional and multiphase systems" » "phased transactional and multiphase systems", "based transactional and multiphase systems", "phase transictions and multiphase systems"
"phase transactions and multiphase systems" » "phase transictions and multiphase systems", "phase transitions and multiphase systems", "base transactions and multiphase systems"

Try widening your search to All Fields.

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: (("phase transactional and multiphase systems") OR ("phase transactions and multiphase systems")).
• Removing quotes may allow a broader search: (( phase transactional and multiphase systems ) or ( phase transactions and multiphase systems )).
• Adding a wildcard symbol may retrieve word variants: (("phase transactional and multiphase systems") or ("phase transactions and multiphase systems"))*.
