This uses an anagram combined with a container (envelope) - an anagram involves rearranging letters based on an indicator word, while a container means one set of letters goes inside another.
Look for the anagram indicator 'resolved' which tells you to rearrange the letters of 'search'. Then find what 'right' abbreviates to, and put those letters 'in the centre' of your anagram.
Answer: CHARTRES | 'Resolved' indicates an anagram of 'search' giving CHARES. 'Right' abbreviates to RT, which goes 'in the centre' (envelope/container) of CHARES to give CH-RT-ARES = CHARTRES.
