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), improvedd\" (Expand Search)
improvee\" » improveee\" (Expand Search), improvedee\" (Expand Search), improve\" (Expand Search), improved\" (Expand Search)
improveedee\" » improveeedee\" (Expand Search), improvedeedee\" (Expand Search), improvedee\" (Expand Search), improveee\" (Expand Search), improveddee\" (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 improvee\\")) OR (\\\"theatre improveedee\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv OR improveed ) OR improvee )) OR (\ theatre improveedee ))~.
