Bootstrap elements on left and right ends - html

Question

I have a filter form at the top which looks like this
and like this in the Mobile Layout
This is my code
<form class="navbar-form " role="search" id="searchform" method="get" action="">
<div class="row">
<div class="col-lg-6 col-md-6 col-xs-12">
<div class="form-group ">
Results per page:
<select class="form-control" name="perpage" id="perpage" onchange="this.form.submit()">
<option value="5" selected="">5</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="50">50</option>
<option value="100">100</option>
</select>
</div>
</div>
<div class="col-lg-6 col-md-6 col-xs-12">
<div class="form-group pull-right">
<input type="text" class="form-control" name="search" id="search" placeholder="Search Keyword" value="">
<button type="submit" class="btn btn-default">Go</button>
<button type="button" onclick="resetform()" class="btn btn-default">Reset</button>
</div>
</div>
</div>
</form>
What can I do with this? I would like it if the search box and the 2 buttons come beside it on the same line without being floated to right but the mobile layout is all messed up. Any suggestions are welcome. Thanks!

UPDATE
Thank you all for your answers. I have upvoted the answers that helped me get what I wanted. However, I ended up doing something of my own.
<div class="col-lg-6 col-md-6 col-sm-6 col-xs-12">
<div class="input-group pull-right">
<input type="text" class="form-control" name="search" id="search" placeholder="Search Keyword" value="<?php echo ($this->input->get('search',true)); ?>">
<span class="input-group-btn">
<button type="submit" class="btn btn-default">Go</button>
<button type="button" onclick="resetform()" class="btn btn-default">Reset</button>
</span>
</div>
</div>

Answer 1

set width:auto;display: inline-block; to input text field
check this fiddle:

Answer 2

Try change to only "col-sm-6" and the class named "pull-right" and add "float-right".
Look at this: https://jsfiddle.net/ceqvpu01/1/
input[type="text"] {
display: inline-block;
width: 100%;
}
#media (min-width: 768px) {
.float-right{
float: right;
}
}

Answer 3

thats because you put the 'col-xs-12' on both form. so each form will takes all of the grid system (12) and the second form will be put below the first because there is no more grid for it. try changing your col-xs-12 to col-xs-6 for both form

Answer 4

Like this? I added col-sm-6 to both, and changed col-xs-12 to col-xs-6
<form class="navbar-form " role="search" id="searchform" method="get" action="">
<div class="row">
<div class="col-lg-6 col-md-6 col-sm-6 col-xs-6">
<div class="form-group ">
Results per page:
<select class="form-control" name="perpage" id="perpage" onchange="this.form.submit()">
<option value="5" selected="">5</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="50">50</option>
<option value="100">100</option>
</select>
</div>
</div>
<div class="col-lg-6 col-md-6 col-sm-6 col-xs-6">
<div class="form-group pull-right">
<input type="text" class="form-control" name="search" id="search" placeholder="Search Keyword" value="">
<button type="submit" class="btn btn-default">Go</button>
<button type="button" onclick="resetform()" class="btn btn-default">Reset</button>
</div>
