copied!<p><strong>UPDATE</strong>: As of MongoDB 2.4 one would use a "text" index and full text search query to do this. You can read about them <a href="http://docs.mongodb.org/manual/core/index-text/" rel="noreferrer">here</a>. If using a recent MongoDB the approach below would be silly and unecessary.</p> <p>However, if you have MongoDB < 2.4.0 you could use a regular expression like so:</p> <pre><code>> db.reg.insert({searchword: "win"}) > db.reg.insert({searchword: "window"}) > db.reg.insert({searchword: "Win"}) > db.reg.find() { "_id" : ObjectId("4ecd2e33dd68c9021e453d12"), "searchword" : "win" } { "_id" : ObjectId("4ecd2e36dd68c9021e453d13"), "searchword" : "window" } { "_id" : ObjectId("4ecd2e39dd68c9021e453d14"), "searchword" : "Win" } > db.reg.find({ searchword: /^win$/i }) { "_id" : ObjectId("4ecd2e33dd68c9021e453d12"), "searchword" : "win" } { "_id" : ObjectId("4ecd2e39dd68c9021e453d14"), "searchword" : "Win" } </code></pre> <p>However, your version wasn't working because you don't need the "/"s when using the $regex operator:</p> <pre><code>> db.reg.find({ searchword: { $regex: "^win$", $options: '-i' }}) { "_id" : ObjectId("4ecd2e33dd68c9021e453d12"), "searchword" : "win" } { "_id" : ObjectId("4ecd2e39dd68c9021e453d14"), "searchword" : "Win" } </code></pre> <p>Please note that case insensitive queries do not use the index so it might make sense to make a lowercase searchword field so that you can speed that query up.</p> <p>Go <a href="http://www.mongodb.org/display/DOCS/Advanced+Queries#AdvancedQueries-RegularExpressions" rel="noreferrer">here</a> for more info on RegularExpressions</p>
