When editing () a custom table index on the Index tab in Site Manager -> Administration -> Smart search, you can see a list of custom tables indexed by the index. Custom tables can be added to the index using the Add custom table link. You can also Edit () the way listed custom tables are indexed or Delete () them from the list.
When adding a new custom table to the index or editing an existing one, you have the following options:
|•||Custom table: custom table to be indexed|
|•||Where condition: WHERE part of the SELECT SQL query retrieving data from the table; using this, you can limit which items (rows) in the table will be indexed|
