Keywords Search, search all words

Hello,

I am having trouble rapping my head around the logic of a keyword search. I would like to have a search string input into the procedure to find the keywords in a fieild. This is not too hard, but my problem is making is so that it matches all keywords seperated by spaces in any order. For example if I enter the keywords "Some text" it should find results that have a sentence with "some text" or "text some".

Anyone know how you would go about this?

you can use where condition like [assume @someText is declare variable that has text like "some text"]

Where KeyWord like '%' + REPLACE(@someText,' ','%') + '%'
If you are trying to implement some sort of fuzzy search then you should use Full text index. check the below for details:
http://www.developer.com/db/article.php/3446891/Understanding-SQL-Server-Full-Text-Indexing.htm 
If you just want an exact match of all the keywords regardless of the order, then you can use dynamic SQL like below:
 

declare @strsQL varchar(8000)
declare @col varchar(500)

set @col = '%' + replace(@yourparam, ' ', '% AND Col1 Like %') + '%'

set @strSQL = 'select * from yourtable where col1 like ' + @col

exec(@strSQL)

Open in new window

problem is I am going through a CMS that allows me to use SQL syntax for querying, but I can't use full-text because the data is serialized.
Your second solution is quite creative, however i can only edit the where clause.
not necessarily you can edit whatever you want there. I just included the relevant part based on your initial requirement.
No, what I am saying is, because of my CMS, i can only provide the where clause, so I need a solution that can be done with a creative where clause.
well, if you just want the WHERE clause then
declare @strsQL varchar(8000)
declare @col varchar(500)

set @col = '%' + replace(@yourparam, ' ', '% AND Col1 Like %') + '%'

set @strSQL = 'where col1 like ' + @col

exec(@strSQL)

Open in new window

I can put a declare inside a where clause?

I still dont think you understand what I am saying

I can only change the WHERE clause of a query, and I cannot do anything else through the CMS.

in the query  for example

select name from people
where name = 'me'

I can only change "where name ='me'"
And that's what the above will do.
declare @strsQL varchar(8000)
declare @col varchar(500)

set @col = '''%' + replace(@yourparam, ' ', '''% AND Col1 Like %''') + '%'''

set @strSQL = 'where col1 like ' + @col

That will give you something like
"WHERE col1 like '%some%' and col1 like '%text%' "
Isn't that what you want? IF not please post a clear example of what are you looking for.
Ralmada, thank you for your persistence.
I am working with a CMS called DotNetNuke. I am using the Forms and List module, which allows me to put in a filter statement using SQL syntax which effectively is the Where clause of a SQL statement. I cannot put dynamic SQL into this where clause, it has to be sql syntax you could normally place in a where clause.

Is that clear?
