As per the docs, when I hit the query:

db.sample.find({ $text: { $search: "cakes \"coffee shop\"" } })

It should return all documents containing "coffee shop" OR "cakes". So it should return both documents. But it isnt happening. Contradicting to the definition given on the docs, it return only one doc from the data set:

{
    "_id" : ObjectId("5ad609baac1a8b644180936b"),
    "content" : "coffee shop..."
}

Here is the full data set:

/* 1 */
{
    "_id" : ObjectId("5ad609a2ac1a8b644180936a"),
    "content" : "Coffee and cakes..."
}

/* 2 */
{
    "_id" : ObjectId("5ad609baac1a8b644180936b"),
    "content" : "coffee shop..."
}

Text index was already created for the field "content". Results are contradicting the definition (under Exact Phrase) text search docs:
