Perhaps you should try some spelling variations:
"association single and algebras" » "association using and algebras", "associated single and algebras", "association sacla and algebras"
"association mining and algebras" » "association mapping and algebras"
"association rings and algebras" » "association brings and algebras", "associative rings and algebras", "association during 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 rings and algebras") OR ("association single and algebras"))) OR ("association mining and algebras")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"association rings and algebras\") OR (\"association single and algebras\"))) or (\"association mining and algebras\"))".
• Removing quotes may allow a broader search: (((( association rings and algebras ) OR ( association single and algebras ))) or ( association mining and algebras )).
• Adding a wildcard symbol may retrieve word variants: (((("association rings and algebras") OR ("association single and algebras"))) or ("association mining and algebras"))*.
