Perhaps you should try some spelling variations:
"c's communication ireland" » "c's communication iceland", "c's communication finland", "c's communication iran", "lea's communication ireland", "class communication ireland", "les communications ireland"
"mass communication india" » "mass communication media", "mass communications media", "maps communication india"
"u.s migration history" » "mass migration history", "does migration history", "1 migration history"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mass communication india\") OR (\"c's communication ireland\"))) OR (\"u.s migration history\"))~".
• Removing quotes may allow a broader search: (((( mass communication india ) OR ( c's communication ireland ))) OR ( u.s migration history ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mass communication india") OR ("c's communication ireland"))) OR ("u.s migration history"))*.
