What is full-text indexing?
A full-text index is a special type of index that provides index access for full-text queries against character or binary column data. A full-text index breaks the column into tokens and these tokens make up the index data.
Does indexing lock the table?
Yes you can. It will lock the table you’re adding an index to while it’s being created. If the table is large, it may take awhile as it has to read each row while building the index.
How do I make a column full-text indexed?
To create a full text index choose your table and right click on that table and select “Define Full-Text Index” option. Now select Unique Index. It is compulsory that for “Full Text Index” table must have at least one unique index. Select columns name and language types for columns.
Does creating a non clustered index lock the table?
Yes it will lock the table. For a nonclustered index, should be a shared lock, so just blocks writers. Unless you have Enterprise edition and can build the index online.
Why is full text index grayed out?
If “Full-Text Indexing” is greyed out it means that full-text indexing is not enabled. NOTE: If you are using SQL Server 2012 Please see the SQL Server 2012 notes at the bottom of this article.
How does the full text index work in SQL Server?
Specifies whether changes (updates, deletes, or inserts) made to table columns that are covered by the full-text index will be propagated by SQL Server to the full-text index. Data changes through WRITETEXT and UPDATETEXT are not reflected in the full-text index, and are not picked up with change tracking.
What happens when the full text index exceeds the limit?
The full-text index exceeds the limit for the number of rows that can be contained in a full-text catalog. A clustered index or full-text key index on the table being indexed gets altered, dropped, or rebuilt.
When do I add a column to a full text index?
Whether the full-text index is populated after a column is added or dropped from a full-text index depends on whether change-tracking is enabled and whether WITH NO POPULATION is specified. For more information, see Interactions of Change Tracking and NO POPULATION Parameter.
What causes full text index to go offline?
A clustered index or full-text key index on the table being indexed gets altered, dropped, or rebuilt. A hardware failure or disk corruption results in the corruption of the full-text catalog. A file group that contains the table being full-text indexed goes offline, or is made read-only.
