Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improveee\\" » improveeee\\" (Expand Search), improvedeee\\" (Expand Search), improve\\" (Expand Search), improved\\" (Expand Search)
improveed\" » improveeed\" (Expand Search), improvedeed\" (Expand Search), improved\" (Expand Search), improve\" (Expand Search)
improveeeeeeed\\" » improveeeeeeeed\\" (Expand Search), improvedeeeeeeed\\" (Expand Search), improveeeeed\\" (Expand Search), improvedeeeed\\" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((\\\"theatre improv\\\") OR (\\\"theatre ((improveee\\\" OR improveed\\") OR improveeeeeeed\\\")))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre improv\ ) OR (\ theatre ((improveee\ OR improveed ) OR improveeeeeeed\ ))).
