Perhaps you should try some spelling variations:
"canadian research claire" » "italian research claire", "asian research claire", "canadian research care", "canadian research clara", "canadian research chapitre"
"can research claip" » "can research class", "can research claes", "can research clara", "main research claip", "cancer research claip", "human research claip"
"can research chap" » "can research can", "can research ch", "can search chap", "main research chap", "cancer research chap", "human research chap"

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: (((("can research claip") OR ("can research chap"))) OR ("canadian research claire")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"can research claip\") OR (\"can research chap\"))) or (\"canadian research claire\"))".
• Removing quotes may allow a broader search: (((( can research claip ) OR ( can research chap ))) or ( canadian research claire )).
• Adding a wildcard symbol may retrieve word variants: (((("can research claip") OR ("can research chap"))) or ("canadian research claire"))*.
