Tarantool: limit/offset in index.indexName:pairs call
<p>I need to fetch some records from space <code>users</code>.
This space has a secondary index <code>category_status_rating</code>.
I need select users with <code>category=1</code>, <code>status=1</code>,  <code>rating&lt;=123456789</code>:</p>

<pre><code>for _, user in box.space.users.index.category_status_rating:pairs({ 1, 1, 123456789 }, { limit = 20, offset = 5, iterator = box.index.LE }) do
    if user[categoryIdx] ~= 1 or user[statusIdx] ~= 1 then break end
    table.insert(users, user)
end
</code></pre>

<p>As I know, iteration with <code>indexName:pairs</code> does not support <code>limit</code> and I can just user my own counter. But what about <code>offset</code>? Can I use this param and start from "page" I need? Or will I iterate without any <code>offset</code> and pass useless records (about 100000) and start to <code>table.insert(users, user)</code> when  my "page" starts? 
Thanks!</p>
