To include a column in the index, select the check box next to the column name. Columns that are not eligible for full-text indexing appear in grey with their check boxes disabled.
Language for Word Breaker
Select a language from the drop-down list. This choice will be used by SQL Server to identify the correct word breakers for the index. SQL Server uses word breakers to identify word boundaries in the full-text indexed data.
Data Type Column
Select the name of the column that holds the document type of column being full-text indexed.
The Data Type Column is only enabled when the column named in the Available Columns column is of type varbinary(max) or image.
