Support MongoDB Queries

I need support for three things.

1.- Index correctly one database to make one query faster.

2.- I have a piece of code in Node with MongoClient that does 7 queries in the same collection to get a certain number of objects. For example, my collection is "Audios". I want 3 audios of language "es", 2 audios of language "en", etcetera. Can those Audios be random? Can it be in only one query? At the moment I do as many queries as languages I want. I will provide actual code, and the actual response I'm looking for.

3.- I have two queries that do regex. One is ^Tom (starts with Tom) and the second is .*Tom.* (contains Tom). I want to display FIRST the one starting with Tom and then, if there are no more, show the one containing Tom. Can you do this with only 1 query?

Taidot: node.js, NoSQL Couch & Mongo
