INNER JOIN App ap
  ON cat.CategoryID = ap.CategoryID
INNER JOIN SubCategory subcat
  ON subcat.SubCategoryId = ap.SubCategoryId
WHERE FREETEXT (
    cat.CategoryName
    ,@searchparameter
    )
  OR FREETEXT (
    subcat.SubCategoryName
    ,@searchparameter
    )
  OR FREETEXT (
    ap.AppName
    ,@searchparameter
    )
  OR CONTAINS (
    ap.AppDetails
    ,@searchparameter
    )
  OR CONTAINS (
    cat.CategoryName
    ,@searchparameter
    )
  OR CONTAINS (
    subcat.SubCategoryName
    ,@searchparameter
    )
  OR CONTAINS (
    ap.AppName
    ,@searchparameter
    )
  OR CONTAINS (
    ap.AppDetails
    ,@searchparameter
    )

USE [AppStore]
GO

DECLARE @return_value INT

EXEC @return_value = [dbo].[IndianAppStore_Search] @searchparameter = N'wishpicker'

SELECT 'Return Value' = @return_value
GO

In the AppName column in App table there is a row which contains wishpicker as an AppName i want to show this result even if the user writes only wish for the search query.

Is that possible with freetext or any other search algo in sql server?

Answer 1

Read up on the LIKE keyword. But in short...

WHERE (ap.AppName LIKE 'wish%')  -- Finds app names BEGINNING with wish
WHERE (ap.AppName LIKE '%wish%') -- Finds app names CONTAINING wish
WHERE (ap.AppName LIKE '%wish')  -- Finds app names ENDING with wish

Answer 2

How about adding this condition?

OR (@searchparameter = 'wish' and ap.AppName = 'wishpicker')

Or, if the AppName field needs wildcards:

OR (@searchparameter = 'wish' and ap.AppName like '%wishpicker%')
