Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improvede\\" » improveede\\" (Expand Search), improvedede\\" (Expand Search), improved\\" (Expand Search), improve\\" (Expand Search)
improvededed\" » improveededed\" (Expand Search), improvedededed\" (Expand Search), improvedded\" (Expand Search), improveded\" (Expand Search)
improvedeed\" » improveedeed\" (Expand Search), improvededeed\" (Expand Search), improveded\" (Expand Search), improveed\" (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 (improvede\\\" OR (improvededed\\" OR improvedeed\\"))))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre improv\ ) OR (\ theatre (improvede\ OR (improvededed OR improvedeed )))).
