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)
improvededdeed\" » improveededdeed\" (Expand Search), improvedededdeed\" (Expand Search), improvedddeed\" (Expand Search), improveddeed\" (Expand Search)
improvedd\" » improveedd\" (Expand Search), improvededd\" (Expand Search), improved\" (Expand Search), improve\" (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 (improvededdeed\\" OR improvedd\\"))))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre improv\ ) OR (\ theatre (improvede\ OR (improvededdeed OR improvedd )))).
