Perhaps you should try some spelling variations:
"export fare integration theories." » "export fare integration theorems.", "export fare integrationstheorie 2.", "export fare integration theory.", "export trade integration theories.", "export die integration theories.", "export share integration theories.", "export base integration theories.", "export fair integration theories."
"import data lending services." » "import data nonlending services.", "import data planning services.", "import data banking services.", "import data sending services.", "import data linking services.", "import data finding services.", "import duty lending services."

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: (("export fare integration theories.") OR ("import data lending services."))~.
• Removing quotes may allow a broader search: (( export fare integration theories. ) or ( import data lending services. ))~.
• Adding a wildcard symbol may retrieve word variants: (("export fare integration theories.") or ("import data lending services."))*.
