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)
improvededeeedee\" » improveededeeedee\" (Expand Search), improvedededeeedee\" (Expand Search), improveddeeedee\" (Expand Search), improvedeeedee\" (Expand Search)
improveed\" » improveeed\" (Expand Search), improvedeed\" (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 improvede\\") OR improvededeeedee\\")) OR (\\\"theatre improveed\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improvede ) OR improvededeeedee )) OR (\ theatre improveed )).
