Description

SERVER-23882, implemented in version 3.3.10 of the server, introduced collation as part of a query's shape.  Despite a specific note in the description of the ticket, it looks like the documentation was never updated to reflect the change.  The entry on the glossary page currently still reads as follows:

A combination of query predicate, sort, and projection.

Relatedly, the PlanCache.getPlansByQuery() documentation currently states that the command has the following definition:

db.collection.getPlanCache().getPlansByQuery( <query>, <projection>, <sort> ) 

But it actually accepts a fourth argument which is the collation:

> db.foo.getPlanCache().getPlansByQuery
function(query, projection, sort, collation) {
    return this._runCommandThrowOnError("planCacheListPlans",
                                        this._parseQueryShape(query, projection, sort, collation));
} 

Worth noting here: the getPlansByQuery() function was deprecated in version 4.2 and is now removed as of 4.4.  At the time of writing, version 3.6 reaches EOL this month but versions 4.0 and 4.2 will still be supported for a while.
