### 3.6 Multi-server Queries

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.

Variable: eudc-inline-expansion-servers

  This variable controls which servers are tried and in which order when trying to perform an inline query. Possible values are:

  `current-server`

    Only the current directory server is tried

  `hotlist`

    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

  `server-then-hotlist`

    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.

Variable: eudc-max-servers-to-query

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