Perhaps you should try some spelling variations:
"conservatively" » "conservationly", "consecutively", "cooperatively"
"conservative" » "conservation", "consecutive", "cooperative"
"conservations" » "conservation", "conversations", "considerations"
"observations" » "observation", "observational", "operations"
"connection" » "collection", "correction"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("conservatively" or "conservative") or (("conservations" or "observations") or "connection"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("conservatively" OR "conservative") OR (("conservations" OR "observations") OR "connection")).
• Removing quotes may allow a broader search: (( conservatively or conservative ) or (( conservations or observations ) or connection )).
• Adding a wildcard symbol may retrieve word variants: (("conservatively" or "conservative") or (("conservations" or "observations") or "connection"))*.
