regular expression for single quote mark in mongodb

Question

in mongodb shell client, how can I query to find documents with single quotes? I escaped the quote mark in regex. but it does not work.

db.coll.find({field: /\\\         


        

Answer 1

This should work:

db.coll.find({field: /\x27/});

Where 0x27 is Unicode APOSTROPHE

From documentation:

MongoDB regex queries support UTF-8 in the regex string.
