edit: forms.less from bootstrap 3.2

uncomment line 411 and 422

Just add to your custom css file:

.navbar-form .input-group {
    display: table;
}
.navbar-form .input-group .input-group-addon,
.navbar-form .input-group .input-group-btn {
    white-space: nowrap;
    width: 1%;
}
.navbar-form .input-group .form-control {
    width: 100%;
}

I had the same unexpected experience as I upgraded from 3.1.1 to 3.2.0 - my (top) navbar-form which used to take full width of the screen was now just a short element. This is what worked for me in my custom CSS that loads up after Boostrap (that's how I override Bootstrap while preserving their original clean minified version):

/* Boostrap CSS 3.2.0 had these new lines in the navbar-form that
   were different from 3.1.1 [it's all in @media (min-width: 768px)
   so this behavior only shows up on higher resolutions] */
.navbar-form .input-group {
    display: inline-table;
    vertical-align: middle;
}
.navbar-form .input-group .input-group-addon,
.navbar-form .input-group .input-group-btn,
.navbar-form .input-group .form-control {
    width: auto;  /* HERE IS THE CULPRIT */
}
/** SOLUTION: in custom CSS **/
/* make sure navbar-form's input-group goes 100% i.e. full width of screen 
   to compliment the display: inline-table; that showed up in 3.2.0 */
.navbar-form .input-group {
      width: 100%;
}
/* override width: auto; that showed up in 3.2.0
   with at least 1px for the addon or btn (I had an addon) */
.navbar-form .input-group .input-group-addon,
.navbar-form .input-group .input-group-btn {
      width: 1px;
}
/* separate .form-control and give it width: 100%; */
.navbar-form .input-group .form-control {
        width: 100%;
}
