        <input type="text" class="form-control input-sm" placeholder="Value" name="SearchValue">
        <input type="text" class="form-control input-sm second-value" placeholder="Value" style="display:none;" name="SearchValue1">
        <button type="button" class="btn btn-default btn-Add">+</button>

    </div>
    <div id="othersearch"></div>
    <input type="submit" value="Search" class="btn btn-primary" />
}

When ever you add a element dynamically make sure you also set it a name. so when you add a new input element it must be

 <input type="text" name="NewTextBox" class="form-control input-sm" placeholder="Value" name="searchvalue">

So like this no matter how many text boxes you add, All will have same name. Once you post the form. In your controller do this.

[HTTPPOST]
public ActionResult Search(MyModel newModel,string[] NewTextBox)
{
 // here as you had dynamic textbox with name = NewTextBox you 
 //will get all its value binded to the above string[]

}

You can retrive them using Request.form["NewTextBox"] as

[HTTPPOST]
public ActionResult Search(MyModel newModel) 
{ 
 var values = Request.Form[NewTextBox];    
}

But I would recommend you the first approach where you use the MVC Model Binder to take care of all the things. You will just have array of values to play with.

NOTE: Always make sure you get the names right, and use the name right while playing with MVC. As all the binding depends on the naming itself.

You can get value of all textboxes having same name using following code:

    var results = ((String[])formcollection.GetValue("mytxt").RawValue).ToList();
            foreach (var item in results)
            {
                //string name = item;
            }
