How do i make full text search search for partial words and individual words

I’m currently using full text search on 3 fields in my database, e.g. name, sku, details
However were having difficulty getting the search to work as expected e.g.
1)  We’re searching for whole lines and not each word as say google for example e.g. Lets say we have a detail of “the cat sat on the mat” then searching for “cat"  or “cat sat” will work but searching the “cat mat” won’t, so my question is, is there a way to have fts work smarter and break down the contents.
2)  partial word search don’t work as per the example above if I search for “ma” nothing will get returned but if I search for “mat” it will, is there a way around this?

My current stored procedure can be found below, and can any replies ideally include how it should be amended please

Thanks in advance

DECLARE @FORMSOF as varchar(1000)
DECLARE @Phrase as varchar(1000)
SET @FORMSOF = 'FORMSOF (INFLECTIONAL, "' + @SearchText + '")'
SET @PHRASE =  '"' + @SearchText  + '"';
WITH Products AS
(
	SELECT ID, [Name], Sku, Origin, Price, ROW_NUMBER() over (ORDER BY ID) AS 'RowNumber'

	FROM mytable P
	WHERE 
		P.Active = 1
		and
		(
			CONTAINS(Name, @FORMSOF) --Search for forms of input text in product name
			OR CONTAINS(Detail, @FORMSOF) -- Search for forms of input text in product description
			OR CONTAINS(Origin, @PHRASE) -- Search for input text in Origin field
			OR SKU Like '%' + @SearchText + '%' -- Search for input text in Sku field
		)
)

SELECT * FROM Products

Hi,

How do you format @SearchText?

You need to have an op between each word, like

' "cat" AND "mat" '

With partial search you 'll need

' "cat" AND "ma*" '

at the minute the @searchText come in as 'the cat sat on the mat'

Is there a way in sql to split this to say something like replace every space with "* AND " ?

so
'the cat sat on the mat'

would then be
'the* AND cat* AND sat* AND on* AND the* AND mat'

and if so is this the best way to do it do you think?

I would recommend you to build the searchtext where you interact with the user, that is, in your gui.

But you should be able to to something like

@SearchText = '"' + REPLACE(@SearchText, ' ', '*" AND "') + '*"'

This expect the text to be formatted with only one space between the words, and no other spaces.
