I wrote an open source JavaScript library called ObjectId.js. I'd like to know who is using it. I assume most people (if anyone is using it) are including a local copy of ObjectId.js in their web folder and including it via:

<script type="text/javascript" src="path-to/ObjectId.js"/>

So my question is: can I search Google, Bing etc. for web pages that include a JavaScript file called ObjectId.js?

  • Does inurl:ObjectId.js work?

You could take a look at MAMA (MAMA is a structural Web-page search engine).

The reason why you can’t search Google/Bing is that they do not index the whole page. They parse through it and take out the HTML tags and any extra information they don't need, like scripts/HTML tags etc. and index the left over text. And that is what you search.

EDIT They do store a cache of the full page's HTML, but this does not mean that it is indexed. They will only index the viewable text that end users can read.

  • Ok I feel pretty stupid, buy I can't find the link for the form I can start searching with. Commented Sep 13, 2013 at 17:07

    For anyone else looking, the links above no longer work. you could instead use publicwww.com though this has a freemium pricing model. Commented Feb 12, 2018 at 9:41
