MongoDB: Is it possible to make a case-insensitive query? -

-

उदाहरण: 

  & gt; db.stuff.save ({ "foo": "बार"}); & Gt; । Db.stuff.find ({ "foo": "बार"}) गिनती (); 1 & gt; । Db.stuff.find ({ "foo": "बार"}) गिनती (); 0

आप उपयोग कर सकते हैं।

आपके उदाहरण में होगा: 

  db.stuff.find ({foo: / ^ बार $ / i});

मुझे कहना चाहिए, यद्यपि, शायद आप इसे जितना भी समय पाते हैं उतनी अतिरिक्त लागत के बजाय रास्ते में मूल्य को डाउनकेस (या अपकेस) कर सकते हैं। जाहिर है, यह लोगों के नामों और ऐसे लोगों के लिए काम नहीं करता है, लेकिन हो सकता है कि वे टैग्स जैसे- टैग का उपयोग करें।

Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
