CONTAINS keyword usage in CMIS queries

Hello,

I have CONTAINS keyword usage question. I am using Alfresco 5.0.d and trying to query my custom type objects via CMIS like this:
SELECT * FROM custom:type WHERE CONTAINS('test')

I tested this query via OpenCMIS Workbench. I expected to get all custom:type entries where at least one of my custom attributes has the text 'test'. But I guess I misunderstood how CONTAINS keyword works with CMIS - I get no results.

I found this earlier post which describes similar problem:
http://forums.alfresco.com/forum/developer-discussions/alfresco-api/cmis-contains-not-finding-documents-expected-03142011-1523
And I thought that this was fixed in version 3.4.3.. but it appears it is not the case.

I also tried this (same results as before):
SELECT * FROM custom:type WHERE CONTAINS('TEXT:test')
and this (I get an exception):
SELECT * FROM custom:type WHERE CONTAINS('ALL:test')
The latter query resulted in an error in workbench ("runtime: 08091542 Request failed 500 /solr4/alfresco/cmis...") and in alfresco logs:

ERROR [solr.core.SolrCore][http-bio-8443-exec-3] java.lang.UnsupportedOperationException

So the questions at hand are:
How should CONTAINS keyword work?
Is it possible to achieve my requirement (search in all attributes, without specifying all of them in the query)?
