Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improveedeedede\" » improveeedeedede\" (Expand Search), improvedeedeedede\" (Expand Search), improvedeedede\" (Expand Search), improveddeedede\" (Expand Search)
improvee\" » improveee\" (Expand Search), improvedee\" (Expand Search), improve\" (Expand Search), improved\" (Expand Search)
improveeed\" » improveeeed\" (Expand Search), improvedeeed\" (Expand Search), improveed\" (Expand Search), improveded\" (Expand Search), improved\" (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 ((improveedeedede\\" OR improvee\\") OR improveeed\\")))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre improv\ ) OR (\ theatre ((improveedeedede OR improvee ) OR improveeed )))~.
