Filter data in CouchDB as IN in MySQL

I am wondering if i could filter data in Couchdb similar with IN in MySQL. For example the map function is :

function(doc) {
  emit(doc.idWord, [doc.idTwitterData, doc.tf*doc.idf]);
}

I want to select only documents that have idWord with values 1 or 5 for example. I tried to set startkey=1 and endkey=5 but it is not working.

It's very simple. All you need to query is ?keys=[1,5]. This will fetch all the records with the idWord equal to 1 or 5. You might want to encode the [ ]

As an addition: you use the parameters startkey and endkey if you are doing a ranged query. Here is a good explanation how a ranged query works.
