Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improvedeed\" » improveedeed\" (Expand Search), improvededeed\" (Expand Search), improveded\" (Expand Search), improveed\" (Expand Search)
improvedeee\\" » improveedeee\\" (Expand Search), improvededeee\\" (Expand Search), improvedee\\" (Expand Search), improveee\\" (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 improvedeed\\") OR improvedeee\\\")) OR (\\\"theatre improvede\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improvedeed ) OR improvedeee\ )) OR (\ theatre improvede\ )).
