Is it possible to install Fulltext on multiple servers as a failover?
By product design, this would not be possible. File cabinets can only be configured with one Fulltext connection.

A wildcard search shows all index entries containing the search term in different combinations. The following is an example of how the asterisk would be used to perform a wildcard search; *Engineering*
