Perhaps you should try some spelling variations:
"basic projective a–modules p" » "basic properties a–modules p", "basic projection _–modules p", "basic projective a–modules _", "basic projective a–modulus _", "basic projective a–nodules _"
"basic properties a OR properties _ –modules p" » "basic properties va OR properties _ –modules p", "basic properties via OR properties _ –modules p", "basic properties a OR properties _ –modules _", "basic properties a OR properties _ –modulus _", "basic properties a OR properties _ –nodules _"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("basic projective a–modules p") or ("basic ((properties a) OR (properties _))–modules p"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("basic projective a–modules p") OR ("basic ((properties a) OR (properties _))–modules p"))*.
• Removing quotes may allow a broader search: (( basic projective a–modules p ) or ( basic ((properties a) OR (properties _))–modules p ))*.
