Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improveedeed\" » improveeedeed\" (Expand Search), improvedeedeed\" (Expand Search), improvedeed\" (Expand Search), improveddeed\" (Expand Search)
improvee\\" » improveee\\" (Expand Search), improvedee\\" (Expand Search), improve\\" (Expand Search), improved\\" (Expand Search)
improveee\\" » improveeee\\" (Expand Search), improvedeee\\" (Expand Search), improvee\\" (Expand Search), improvede\\" (Expand Search), improve\\" (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 improveedeed\\")) OR (\\\"theatre (improvee\\\" OR improveee\\\")))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre (improv\ OR improveedeed )) OR (\ theatre (improvee\ OR improveee\ )))~.
