Creating Full Text Index in SQL Server


In this article we will see how to create a full text search index for SQL Server database for effective search. In so many cases we need to provide the search facility in our application. To provide searching facility within our local database we can use the greater feature provided by Microsoft SQL Server i.e. full text index.


When we want to use the full text index service we need to start the service first else it will raise the errors. So let's start with how to start the service and use the Full text index step by step.

Step 1

Open SQL Server and create a new database with the following table for eg. Tbl_Search but keep in mind that the full text index only works on primary key or unique key containing tables.

Create Table Tbl_Search
Id Int Primary Key Identity(1,1),
Title Varchar(500),

Insert some rows in the created table.

Step 2

Now we will create full text index on our database and table for providing search in table. So create the Full Text Catalog on our database by using following query.


In the query above we have created FullText Catalog with the name FTSearch.

Step 3

Now we will create full text index on our table Tbl_Search but for that we require the unique key id or primary key id so find the id of unique or primary key by using following command.


This command will display the all constraint names on tables present in our database from the output. Copy the Tbl_Search constraint name for creating a full text index on TblSearch.


(Title, [Desc] LANGUAGE 1033)

KEY INDEX PK__Tbl_Sear__3214EC0700551192

ON FTSearch

In the above statement you can see we are creating a FullText Index on table name with a parameter; this parameter is nothing but the column name of the table on which we want to create the full text index and language 1033 denotes the language English.

Step 4

Now it's time to search the records in a specified indexed table. For that we can write the queries like below.

Select * from Tbl_Search Where Contains(Title,'Asp.Net')

Select * from Tbl_Search Where Freetext([Desc],'Asp.Net')

In the preceding queries you can see we have given a where clause with column name which is the column we want to search and what we want to search. The preceding queries retrive the rows of a table which contain ASP.Net in title column and the second query will retrieve the rows of ASP.Net in the desc column.

In some cases your queries gives an error like fdhost cannot be started. That means your FullTextIndex Service is not started; for that you have to first start the Demon Launcher for FullTextIndex service.

Step 5

For starting FullTextIndex service go to SQL Server Tool->SQL Server Configuration Manage->Service->FullTextSearch Demon Launcher if it is stopped then start this service for performing search operation with a contains and FreeText clause and restart the SQL Server instance.


In this way we can use the FullTextIndex on our database.
