Perhaps you should try some spelling variations:
entr » entry, entre, entra
entravent » entryavent, entreavent, entraavent, entrant, entrent
entrapment » entryapment, entreapment, entraapment, entrainment
entryto » entryyto, entreyto, entrayto, entrato

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((entr OR (entravent OR entrapment)) OR entryto)(('act OR 'acted ) OR 'acute ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((entr or (entravent OR entrapment)) or entryto)(('act or 'acted ) or 'acute )".
• Adding a wildcard symbol may retrieve word variants: ((entr or (entravent OR entrapment)) or entryto)(('act or 'acted ) or 'acute )*.
