Perhaps you should try some spelling variations:
"association being and algebras" » "associations being and algebras", "association testing and algebras", "association meeting and algebras"
"association brief and algebras" » "association erie and algebras", "association brings and algebras", "association based and algebras"
"association using and algebras" » "association mining and algebras"

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: (((("association being and algebras") OR ("association brief and algebras"))) OR ((("association using and algebras") OR ("association mapping and algebras")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"association being and algebras\") or (\"association brief and algebras\"))) or (((\"association using and algebras\") OR (\"association mapping and algebras\"))))".
• Removing quotes may allow a broader search: (((( association being and algebras ) or ( association brief and algebras ))) or ((( association using and algebras ) OR ( association mapping and algebras )))).
• Adding a wildcard symbol may retrieve word variants: (((("association being and algebras") or ("association brief and algebras"))) or ((("association using and algebras") OR ("association mapping and algebras"))))*.
