The LiveSearch action is the same as Search except that it automatically submits the search conditions to the server as you type. This has an upside and a downside: it provides more feedback to the user (they can see the search working), but it can be inefficient with server resources.
columns local
The set of searchable columns. This list defaults to the textual database fields.
full_text_search global local
A flag for whether the search should do full-text searching in the database (LIKE %?%) or assume that search tokens will match the beginning (LIKE ?%). Default is :true.
link global
The action link used to tie the Search box to the List table. See API: Action Link for the options on this setting.
