When using inline query expansion (see Inline Query Expansion), EUDC can try to query successively a sequence of directory servers until one of them successfully finds a match for the query.
This variable controls which servers are tried and in which order when trying to perform an inline query. Possible values are:
- Only the current directory server is tried
- The servers in the hotlist are tried in order until one finds a match for the query or `eudc-max-servers-to-query' is reached
- The current server then the servers in the hotlist are tried in the order they appear in the hotlist until one of them finds a match or `eudc-max-servers-to-query' is reached. This is the default.
