Perhaps you should try some spelling variations:
terrestrial applications » industrial applications, potential applications, industrial application
terrestrial pollution » industrial pollution
terrestrial relations » terrestrial vegetation, terrestrial radio
industrial relations » industrial applications

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: ((((terrestrial pollution) OR (((terrestrial relations) OR (industrial relations))))) OR (terrestrial applications)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((terrestrial pollution) or (((terrestrial relations) OR (industrial relations))))) or (terrestrial applications))".
• Adding a wildcard symbol may retrieve word variants: ((((terrestrial pollution) or (((terrestrial relations) OR (industrial relations))))) or (terrestrial applications))*.
