Subquery with count problem

[LastModificationDate],
[Comment]

On this table I want to find the test documents so that they can be deleted, hence I have created the query to find documents with the words "test" and "delete" in [Title] and [Comment] looking like this:
SELECT [DocID], [Title],[CreatedByUser], [CreateDate],[LastModifiedByUserName], [LastModificationDate], [Comment]
FROM [DMSDB].[dbo].[KDOCUMENT]
WHERE [Title] LIKE '%test%'
OR [Comment] LIKE '%test%'
OR [Title] LIKE '%delete%'
OR [Comment] LIKE '%delete%'
OR [OnlineVersionsSize] = 0.
This one is working fine returning 5070 rows with documents containing test and delete.

Problem is that we only want to list the documents belonging to users that have X documents or more (for instance 20), because we have to contact the people and ask them which documents actually are test documents. If someone only have 1 document we don't want to bother them, it is more important to clean up the "real heavy" user's documents.
So, I created a query

SELECT COUNT([CreatedByUser]) AS 'Number of docs', [CreatedByUser]
FROM [DMSDB].[dbo].[KDOCUMENT]
WHERE [Title] LIKE '%test%'
OR [Comment] LIKE '%test%'
OR [Title] LIKE '%delete%'
OR [Comment] LIKE '%delete%'
OR [OnlineVersionsSize] = 0
GROUP BY [CreatedByUser]
HAVING COUNT([CreatedByUser]) > 20
ORDER BY COUNT([CreatedByUser]) DESC

returning correctly the number of documents for each user and the user name. It also limits itself to listing only users with a count of 20 or more.

Now, I want to combine these two, listing all documents with DocID and everything where a user has 20 documents or more. But when I do this:

SELECT [DocID], [Title],[CreatedByUser], [CreateDate], [LastModifiedByUserName], [LastModificationDate], [Comment]
FROM [DMSDB].[dbo].[KDOCUMENT]
WHERE [Title] LIKE '%delete%'
OR [Comment] LIKE '%test%'
OR [Title] LIKE '%test%'
OR [Comment] LIKE '%delete%'
OR [OnlineVersionsSize] = 0
AND [CreatedByUser] IN (
SELECT [CreatedByUser]
FROM [DMSDB].[dbo].[KDOCUMENT]
GROUP BY [CreatedByUser]
HAVING COUNT([CreatedByUser]) > 20)

ORDER BY [CreatedByUser]

I lists all the documents as in the first query, returning 5070 rows while it should return about 4715 (I know this by adding up the numbers in the count query).

It has been a long time since I've been working with SQL, and I am struggling a bit here. Can someone help me? I get the same result using EXISTS, and when using = I of course get the error that it is returning more than one row.
