Perhaps you should try some spelling variations:
explored » explores, explore
exploreds » exploress, explores, explorers, explorados
exploress » explores, explorers, explore
explorees » explores, explorers, explore
exploitees » exploiters, exploited, exploits
explorer » explores, explore

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: ((explored OR ((exploreds OR exploress) OR (explorees OR exploitees))) OR explorer).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((explored or ((exploreds or exploress) or (explorees OR exploitees))) or explorer)".
• Adding a wildcard symbol may retrieve word variants: ((explored or ((exploreds or exploress) or (explorees OR exploitees))) or explorer)*.
