Express and MongoDB, problem with escape characters in the collection.find while using $text and $search

Question

as from the MongoDB documentation,

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

would need to insert its escape characters in the collection.find into a variable named query belonging to req.query.name, so, that text index can be used.

var query = req.query.name;

collection.find({ $text: { $search: '"\"' + query + '\""'}})

I also tried

'"\"query\""'

unfortunately what I expected does not work, do you have any solution? thanks

Answer 1

One way to do this is using ES6 template literals . Try this:

var query = `"${req.query.name}"`;

collection.find({ $text: { $search: query}})

OR

var query = '"' + req.query.name + '"';

collection.find({ $text: { $search: query}})

Try this, this will help to make the same query as it is mentioned in Mongodb documentation. and it will use your index as well.

var value = `\\"${query}\\"`;
collection.find({ $text: { $search: value}})

and if by any chance, your outer double quotes are missing, then try this:

var value = `"\\"${query}\\""`
collection.find({ $text: { $search: value}})
