full-text search examples

A. Using CONTAINS with <simple_term>

The following example finds all products with a price of $80.99 that contain the word "Mountain".

USE AdventureWorks2012
GO

SELECT Name, ListPrice
FROM Production.Product
WHERE ListPrice = 80.99
   AND CONTAINS(Name, 'Mountain')
GO

B. Using FREETEXT to search for words containing specified character values

The following example searches for all documents containing the words related to vital, safety, components.

USE AdventureWorks2012
GO

SELECT Title
FROM Production.Document
WHERE FREETEXT (Document, 'vital safety components')
GO

C. Using CONTAINSTABLE

The following example returns the description ID and description of all products for which the Description column contain the word "aluminum" near either the word "light" or the word "lightweight." Only rows with a rank value of 2 or higher are returned.

USE AdventureWorks2012
GO

SELECT FT_TBL.ProductDescriptionID,
   FT_TBL.Description, 
   KEY_TBL.RANK
FROM Production.ProductDescription AS FT_TBL INNER JOIN
   CONTAINSTABLE (Production.ProductDescription,
      Description, 
      '(light NEAR aluminum) OR
      (lightweight NEAR aluminum)'
   ) AS KEY_TBL
   ON FT_TBL.ProductDescriptionID = KEY_TBL.[KEY]
WHERE KEY_TBL.RANK > 2
ORDER BY KEY_TBL.RANK DESC;
GO

D. Using FREETEXTTABLE

The following example extends a FREETEXTTABLE query to return the highest ranked rows first and to add the ranking of each row to the select list. To specify the query, you must know that ProductDescriptionID is the unique key column for the ProductDescription table.

USE AdventureWorks2012
GO

SELECT KEY_TBL.RANK, FT_TBL.Description
FROM Production.ProductDescription AS FT_TBL 
     INNER JOIN
     FREETEXTTABLE(Production.ProductDescription, Description,
                    'perfect all-around bike') AS KEY_TBL
     ON FT_TBL.ProductDescriptionID = KEY_TBL.[KEY]
ORDER BY KEY_TBL.RANK DESC
GO

Here is an extension of the same query that only returns rows with a rank value of 10 or greater:Here is an extension of the same query that only returns rows with a rank value of 10 or greater:

USE AdventureWorks2012
GO

SELECT KEY_TBL.RANK, FT_TBL.Description
FROM Production.ProductDescription AS FT_TBL 
     INNER JOIN
     FREETEXTTABLE(Production.ProductDescription, Description,
                    'perfect all-around bike') AS KEY_TBL
     ON FT_TBL.ProductDescriptionID = KEY_TBL.[KEY]
WHERE KEY_TBL.RANK >= 10
ORDER BY KEY_TBL.RANK DESC
GO

B. Using FREETEXTTABLE

The following example extends a FREETEXTTABLE query to return the highest ranked rows first and to add the ranking of each row to the select list. To specify the query, you must know that ProductDescriptionID is the unique key column for the ProductDescription table.

The following example uses the ProductDescription table of the AdventureWorks2012 database. The query uses the CONTAINS predicate to search for descriptions in which the description ID is not equal to 5 and the description contains both the word "Aluminum" and the word "spindle." The search condition uses the AND Boolean operator.

USE AdventureWorks2012
GO

SELECT Description
FROM Production.ProductDescription
WHERE ProductDescriptionID <> 5 AND
   CONTAINS(Description, 'aluminum AND spindle')
GO
