Query assets with tags via Nuxeo .net client

[Roberto_Baranzi]

Hi all,

In my project I am using the Nuxeo .NET client for querying the assets and until I decided to introduce tags in my project everything worked perfeclty. However, the issue I am facing is querying the assets with more than one tag in the query.

For example, in the Nuxeo repository I have an image asset tagged with the tags: one, two... When I trigger the search via Postman using the following query:

SELECT * FROM Document WHERE dc:title='CorrectTitle' AND ecm:tag='one' AND ecm:tag='second' AND ecm:isTrashed=0 AND ecm:isVersion=0

I get the correct result.

However, when I do the same using the nuxeo .NET client like below the result is empty. When only one tag is included in the search query, the result is correct.

Documents docs = (Documents)_nuxeoClient.Operation("Document.Query")
                .SetParameter("query", "SELECT * FROM Document WHERE dc:title='CorrectTitle' AND ecm:tag='one' AND ecm:tag='second' AND ecm:isTrashed=0 AND ecm:isVersion=0")
                .AddHeader("X-NXDocumentProperties", "*")
                .Execute()
                .GetAwaiter()
                .GetResult();

Can somebody please tell me what is it that is preventing the .NET client from searching for more than one tag in the document?

Hello,

Your NXQL query should be SELECT * FROM Document WHERE dc:title='CorrectTitle' AND ecm:tag IN('one','second') AND ecm:isTrashed=0 AND ecm:isVersion=0" for document with one or second tag. If you need AND (meaning, your need the two tags on the document), it should be SELECT * FROM Document WHERE dc:title='CorrectTitle' AND ecm:tag/* = 'one' AND ecm:tag/* = 'second' AND ecm:isTrashed=0 AND ecm:isVersion=0"

This is described in https://doc.nuxeo.com/nxdoc/nxql/#special-nxql-properties
