MongoDB text search string equality? - mongodb

Question

I'm new to MongoDB and was looking through the docs a few nights ago and saw something that I haven't been able to locate since...
There was an option, I believe it was related to $text search, to treat an array of strings as if they were the same word. The syntax looked something like this:
["cheez", "cheese"],
["donut", "doughnut"],
["chips", "fries", "crisps"],
So a search for "chips" would return all documents indexed with "fries" or "crisps" even if they did not also have "chips".
Please tell me I wasn't dreaming!

mongodb fuzzy text search
The following query searches the title field for the phrase naw yark. It uses the fuzzy default options where:
maxEdits allows up to two character variation of each term in the
given phrase to match the query to a document.
maxExpansions considers up to fifty similar terms for each term in
naw yark to find matches.
prefixLength is disabled.
The query also includes a $limit stage to limit the output to 10 results and a $project stage to:
Exclude all fields except title
Add a field named score
db.movies.aggregate([
{
$search: {
"text": {
"path": "title",
"query": "naw yark",
"fuzzy": {}
}
}
},
{
$limit: 10
},
{
$project: {
"_id": 0,
"title": 1,
score: { $meta: "searchScore" }
}
}
])
The above query returns the following results:
{ "title" : "New York, New York", "score" : 4.392756462097168 }
{ "title" : "New York", "score" : 4.050914287567139 }
{ "title" : "New York Stories", "score" : 3.4838104248046875 }
{ "title" : "New York Minute", "score" : 3.4838104248046875 }
{ "title" : "Synecdoche, New York", "score" : 3.4838104248046875 }
{ "title" : "New York Doll", "score" : 3.4838104248046875 }
{ "title" : "Little New York", "score" : 3.4838104248046875 }
{ "title" : "Escape from New York", "score" : 3.0559897422790527 }
{ "title" : "King of New York", "score" : 3.0559897422790527 }
{ "title" : "Naked in New York", "score" : 3.0559897422790527 }
