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:

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)

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)

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?

then you will have to build your where clause in a programming language, (VB maybe?) to pass it to the CMS. I'm not familiar with Dotnuke programming so I cannot help you there. But, basically, you will have to convert the code I've suggested above to VB (or whatever language you're using), so the end result will be
"WHERE col1 like '%some%' and col1 like '%text%' "
(This is not dynamic SQL, this is the end result, that is the where clause you're looking for).
