Perhaps you should try some spelling variations:
"logician" » "logical", "logica"
"logicians" » "logicals", "logicas", "logiciels"
"logicas" » "logical", "logics", "logica"
"logiciel" » "logiciels", "logical"

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: ((("logician" OR "logicians") OR "logicas") OR "logiciel").
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"logician\" OR \"logicians\") or \"logicas\") or \"logiciel\")".
• Removing quotes may allow a broader search: ((( logician OR logicians ) or logicas ) or logiciel ).
• Adding a wildcard symbol may retrieve word variants: ((("logician" OR "logicians") or "logicas") or "logiciel")*.
