Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improveded\" » improveeded\" (Expand Search), improvededed\" (Expand Search), improved\" (Expand Search), improvedd\" (Expand Search)
improvede\\" » improveede\\" (Expand Search), improvedede\\" (Expand Search), improved\\" (Expand Search), improve\\" (Expand Search)
improvedeedee\" » improveedeedee\" (Expand Search), improvededeedee\" (Expand Search), improvededee\" (Expand Search), improveedee\" (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 improveded\\")) OR (\\\"theatre (improvede\\\" OR improvedeedee\\")))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre (improv\ OR improveded )) OR (\ theatre (improvede\ OR improvedeedee )))~.
