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.
This variable indicates the maximum number of servers to query when
performing a multi-server query. The default,
that all available servers should be tried.
