Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improvededd\\" » improveededd\\" (Expand Search), improvedededd\\" (Expand Search), improveddd\\" (Expand Search), improvedd\\" (Expand Search)
improvedee\\" » improveedee\\" (Expand Search), improvededee\\" (Expand Search), improved\\" (Expand Search), improvede\\" (Expand Search), improvee\\" (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 improvededd\\\") OR improvedee\\\")) OR (\\\"theatre improvede\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improvededd\ ) OR improvedee\ )) OR (\ theatre improvede\ )).
