Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improvedd\\" » improveedd\\" (Expand Search), improvededd\\" (Expand Search), improved\\" (Expand Search), improve\\" (Expand Search)
improvededee\\" » improveededee\\" (Expand Search), improvedededee\\" (Expand Search), improveddee\\" (Expand Search), improvedee\\" (Expand Search)
improvede\\" » improveede\\" (Expand Search), improvedede\\" (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 improvedd\\\") OR improvededee\\\")) OR (\\\"theatre improvede\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improvedd\ ) OR improvededee\ )) OR (\ theatre improvede\ )).
