sql_field_string
Combined string attribute and full-text field declaration.
Multi-value (ie. there may be more than one such attribute declared), optional.
Applies to SQL source types (mysql, pgsql, mssql) only.
Introduced in version 1.10-beta.
sql_attr_string only stores the column
value but does not full-text index it. In some cases it might be desired to both full-text
index the column and store it as attribute. sql_field_string lets you do
exactly that. Both the field and the attribute will be named the same.
Example:
sql_field_string = title # will be both indexed and stored
