lucene query to check if folder exists

aurora7795 — Wed, 08 Nov 2006 13:26:44 GMT

Hi there,I'm trying to write a method that interacts with the WebServices to see if a folder exists in a workspace. Can anyone point me at a lucene query that will do something like this?Thanks!Martin BG

Hi

See
http://wiki.alfresco.com/wiki/Search#Path_Queries

You should be able to get the path of the folder from the node service and then add /*:woof to find the folder called woof. You may have to escape the path (http://wiki.alfresco.com/wiki/Search#ISO_9075_encoding).

Hi Andy.

I have the same problem and I am not able to resolve it. I spent much time for this task but all my tests failed….

The getPath() method bot for the ParentRefence class and the Refence class does not work: it always returns a null value, so I cannot use the path value to create a query correctly.

Could you kindly provide me with an example of code to resolve this problem?

I have the ID of the node….

Thanks for anything.

Sergio

Hi

Maybe I was a bit naive or missed the web service reference ….

The path is not filled in on references returned from the web service API.
It is likely to be filled in in the future.

It is not easy to get paths via the web services.

So you could check for an existing doc in a folder using a lucene query ..


+PARENT:"FolderNodeRef"  +@cm\:name:"name"

You will have to build the FolderNodeRef string as it is not exposed via the WS reference. See NodeRef.toString() for what to do given the store, protocol and uuid. You will only be able to query for immediate children.

Hi,


+PARENT:"FolderNodeRef"  +@cm\:name:"name"
‍‍‍

but this will also find partial matches. At least, it's better than to step through all subfolders and to compare the names. Now, you have only to compare the names that are returned by that query.
