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)
improveedeede\" » improveeedeede\" (Expand Search), improvedeedeede\" (Expand Search), improvedeede\" (Expand Search), improveeede\" (Expand Search), improvedede\" (Expand Search)
improveede\" » improveeede\" (Expand Search), improvedeede\" (Expand Search), improvede\" (Expand Search), improvee\" (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 improveed\\") OR improveedeede\\")) OR (\\\"theatre improveede\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improveed ) OR improveedeede )) OR (\ theatre improveede ))~.
