Use searchable columns in create replication definition to specify which columns to use in the where clause of create subscription or define subscription (or create article for publications) to restrict the rows copied to a subscribing site.
If you do not include a searchable columns clause in a replication definition, you cannot use a where clause in a subscription or article that references that replication definition.
Enclose the names of the searchable columns in parentheses. For multiple searchable columns, separate each column from the next with a comma.
