Perhaps you should try some spelling variations:
delete transactions » late transactions, select transactions, wallets transactions
ieee transactions » eoe transactions, lease transactions, merge transactions
free transactions » free transitions, late transactions, some transactions
free translation » image translation

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: ((((ieee transactions) OR (delete transactions))) OR (((free transactions) OR (free translation)))) on fuzzy systems.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ieee transactions) or (delete transactions))) or (((free transactions) OR (free translation)))) on fuzzy systems".
• Adding a wildcard symbol may retrieve word variants: ((((ieee transactions) or (delete transactions))) or (((free transactions) OR (free translation)))) on fuzzy systems*.
