Perhaps you should try some spelling variations:
"animal's aggressive disorders" » "animal's depressive disorders", "animal's aggressive diseases", "animal's aggressive episodes", "anomalous aggressive disorders", "animal aggression disorders"
"mail's recessive disorders" » "mail's depressive disorders", "mail's responsive disorders", "mail's impressive disorders", "mice recessive disorders"
"build impressive disorder" » "build depressive disorders", "build depression disorder", "build obsessive disorder", "build immersive disorder", "build massive disorder"

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: (((((("animal's aggressive disorders") OR ("animal's depressive disorder"))) OR ("mail's recessive disorders"))) OR ("build impressive disorder"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"animal's aggressive disorders\") OR (\"animal's depressive disorder\"))) or (\"mail's recessive disorders\"))) or (\"build impressive disorder\"))*".
• Removing quotes may allow a broader search: (((((( animal's aggressive disorders ) OR ( animal's depressive disorder ))) or ( mail's recessive disorders ))) or ( build impressive disorder ))*.
