Hi,  
I am in the processing of modifying the text fields in discourse using the jquery.ime plugin. I simply find the corresponding handlebar template and add the required javascript code. But I cannot find the hbs file containing the definition of search text field that appears at the top of the page. Can somebody please tell where can I find this definition?  
Thanks,

It’s [here](https://github.com/discourse/discourse/blob/be1cce503c3576426ac9759d88fdcab4c0b87be2/app/assets/javascripts/discourse/widgets/search-menu-controls.js.es6#L5), and it is a Widget. So you can’t find it in `.hbs` template files.
