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)
improveeed\" » improveeeed\" (Expand Search), improvedeeed\" (Expand Search), improved\" (Expand Search), improveed\" (Expand Search), improveded\" (Expand Search)
improvee\" » improveee\" (Expand Search), improvedee\" (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 (improveed\\" OR improveeed\\"))) OR (\\\"theatre improvee\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ theatre (improv\ OR (improveed OR improveeed ))) OR (\ theatre improvee ))~.
