dears,
i want to select all the the records in the table as the below:

if the search string is "i went to the supermarket yesterday with a friend"
i want to discard these words "i, to, the, with, a" so the remain words are "went supermarket yesterday friend" so i search in the table for the follows:

1-first select * from mytable where title = 'i went to the supermarket yesterday with a friend' the whole string,

2-select any title contains two or more words in the string "went supermarket yesterday friend"
regardless the order of the word

3- at the end select any record contains any word in "went supermarket yesterday friend"

example:

i have three rows in mytable:

1-"i bough a supermarket"
2-"meet your friend in the supermarket"
3-"i went to the supermarket yesterday with a friend"
4-"John went to the supermarket"

the result of the selection must be :

in first row
"i went to the supermarket yesterday with a friend" (exactly same)

in the second or third row (contains 2 words: went, supermarket)
"John went to the supermarket"

in the second or third row
"meet your friend in the supermarket" (contains 2 words: friend, supermarket even if in different order)

in the last row
"i bough a supermarket" (contains 1 word: supermarket )

as a result i need an advanced search engine but i don't want to use temp table because i thing it will make troubles when many users are searching at the same time

thanks on advanced

ok you are right, i tried my self the below:

Declare @products varchar(200) = 'i went to the supermarket yesterday with a friend'
Declare @individual varchar(20) = null

WHILE LEN(@products) > 0
BEGIN
IF PATINDEX('% %',@products) > 0
BEGIN
SET @individual = SUBSTRING(@products, 0, PATINDEX('% %',@products))
SELECT @individual

SET @products = SUBSTRING(@products, LEN(@individual + '|') + 1,
LEN(@products))
END
ELSE
BEGIN
SET @individual = @products
SET @products = NULL
SELECT @individual
END
END

and i get this result:

i
went
to
the
supermarket
yesterday
with
a
friend

i separate them by space now how can i concatenate each two string with each other:
select * from mytable where title like '%i went to the supermarket yesterday with a friend%'

and

select * from mytable where title like '%i went%'

and

select * from mytable where title like '%to the%'

and

select * from mytable where title like '%supermarket yesterday%'

and

select * from mytable where title like '%with a%'

and

select * from mytable where title like '%friend%'

Solution 1

This is not a trivial job, and you are going to have to do some serious reading.
Start with MSDN: http://msdn.microsoft.com/en-us/library/ms142571.aspx[^]
Then try this: http://ewbi.blogs.com/develops/2007/05/normalizing_sql.html[^] once you have done all the basics from the MS links.

SELECT *
FROM dbo.mytable
INNER JOIN FREETEXTTABLE(dbo.mytable,Name,'search Key') FT
ON mytable.Id = FT.[Key]
ORDER BY RANK DESC
