            <title>[SERVER-9106] Include/Exclude Projection Syntax</title>
                <link>https://jira.mongodb.org/browse/SERVER-9106</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hello!&lt;/p&gt;

&lt;p&gt;I have a proposition for impovements in MongoDB. I want to tell about&lt;br/&gt;
db.collection.find() improvements.&lt;/p&gt;

&lt;p&gt;Currently syntax of query with projection is like:&lt;br/&gt;
db.things.find( { param : &quot;value&quot; } , { field1 : 1, field2: 1 } )&lt;/p&gt;

&lt;p&gt;Why don&apos;t change the syntax to&lt;br/&gt;
db.things.find( { param : &quot;value&quot; } , { (include/exclude): [fields]} )&lt;/p&gt;

&lt;p&gt;I&apos;ll try to give you examples that you could understand what I mean:&lt;/p&gt;

&lt;p&gt;db.things.find( { x : 4 } , {include:[_id, j]} )&lt;br/&gt;
db.things.find( { x : 4 } , {exclude:[_id, x]} )&lt;/p&gt;

&lt;p&gt;In such syntax we can use _id field as a usual field, an it is not&lt;br/&gt;
included to projection implicitly. Another advantage is that we can&lt;br/&gt;
just pass array of fields instead of giving 0 or 1 values to field&lt;br/&gt;
names.&lt;/p&gt;</description>
