Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improveeddeed\" » improveeeddeed\" (Expand Search), improvedeeddeed\" (Expand Search), improveddeed\" (Expand Search), improvedddeed\" (Expand Search)
improvee\\" » improveee\\" (Expand Search), improvedee\\" (Expand Search), improve\\" (Expand Search), improved\\" (Expand Search)
improveede\\" » improveeede\\" (Expand Search), improvedeede\\" (Expand Search), improvede\\" (Expand Search), improvedde\\" (Expand Search), improved\\" (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 improveeddeed\\") OR improvee\\\")) OR (\\\"theatre improveede\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improveeddeed ) OR improvee\ )) OR (\ theatre improveede\ )).
