I know that I have documents created on 10/15/2008, so I tried “[_CreationDate] CONTAINS 10/15/2008” and it fails with the same error you’re getting. (It could be that CONTAINS fails since _CreationDate is a date/time and the operation is doing a string comparison. Maybe internally it won’t cast to a string. Not sure about that.)
Subject: => is not a recognized comparison operator.
When you have a problem with a query, it’s usually helpful to try the query manually in a view. And if it fails, try different parts of it until you narrow down the problem.
but when I try to use the [_creationDate] in the query is always comes back with “query not understandable”… but if I change it to $Created… it works… And thanks to you…i did noticed the operator error…
Subject: $Created is not a standard fieldname, and [_CreationDate] does work
Try this search in this database: [$Created] > 8/31/2010
Now try: [_CreationDate] > 8/31/2010
Which one works? You were getting “Query not understandable” because you had syntax errors in your query – but the syntax error wasn’t from using _CreationDate. The help is accurate on this one. I have used this again and again, and it never fails.
And, documents rarely contain a $Created item, and it’s not necessarily the same as the document creation date if it does exist. So even if _CreationDate didn’t work, $Created isn’t a general solution.
