Perhaps you should try some spelling variations:
improv\\" » improve\\" (Expand Search), improved\\" (Expand Search)
improveed\\" » improveeed\\" (Expand Search), improvedeed\\" (Expand Search), improved\\" (Expand Search), improve\\" (Expand Search)
improvede\\" » improveede\\" (Expand Search), improvedede\\" (Expand Search), improved\\" (Expand Search), improve\\" (Expand Search)
improveedede\\" » improveeedede\\" (Expand Search), improvedeedede\\" (Expand Search), improvedede\\" (Expand Search), improveede\\" (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 improveed\\\")) OR (\\\"theatre (improvede\\\" OR improveedede\\\")))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre (improv\ OR improveed\ )) OR (\ theatre (improvede\ OR improveedede\ )))~.
