Here is one that I found:
https://issues.apache.org/jira/browse/CAY-419
The description in the Jira is a bit vague, but the idea seems to be
the same.

#1. I can have a look. Please find JIRA or create a new one
#2. You should create table ID as ObjAttrbute and attach
ExpressionFactory.noMatchExp("id", getId())

1. I can't use expression.match() because it will fail when the

fine in a query.
Yeah, this is a known limitation for in memory processing. We
probably
even
have a Jira to fix it.
If you find the JIRA # I'll see if we can't have a go at fixing it...
2. In the above statement I don't know how to add a andExp() to
only
return
"this", so I get a bigger query result than I need + unecessary
post
processing.
I've run into this problem previously as well, without finding an
elegant solution.
Not sure I understand this.
Since I can't use .match() I want to run expression against the
database to
see if "this" matches the filter, but I don't want *lots* of returned
results where I need to check that "this" is in the list of objects.
If I could create an expression that filtered out all objects that
was not
"this", then I would know that the object matched the expression if
a single record was returned.
