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)
improveeeddde\" » improveeeeddde\" (Expand Search), improvedeeeddde\" (Expand Search), improveeddde\" (Expand Search), improvededdde\" (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 improveeeddde\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ theatre ((improv\ OR improveed ) OR improvee )) OR (\ theatre improveeeddde )).
