Have a search page that works by entering search-results?keywords=[something], and the code looks like this:

@using Examine.LuceneEngine.SearchCriteria
@inherits Umbraco.Web.Macros.PartialViewMacroPage

@{
    string searchTerm = Request.QueryString["keywords"];
    if (String.IsNullOrWhiteSpace(searchTerm))
    {
        searchTerm = "";
    }
    var searcher = ExamineManager.Instance;
    var searchCriteria = searcher.CreateSearchCriteria();
    var query = searchCriteria.GroupedOr(new[] { "nodeName", "name", "title", "bodyText", "seo" }, searchTerm).Compile();
    var searchResults = searcher.Search(query).Where(r => r["__IndexType"] == "content").ToList();
}

@if (searchResults.Any())
{
    <ul class="search-results-box">
        @foreach (var result in searchResults)
        {
            var node = Umbraco.TypedContent(result.Id);
            var pathIds = result["__Path"].Split(',');
            var path = Umbraco.TypedContent(pathIds).Where(p => p != null).Select(p=> new {p.Name}).ToList();
            <li>
                <section class="results-box">
                    <h3>
                        <a href="@node.Url">@String.Join(" > ", path.Select(p => p.Name))</a>
                    </h3>
                    <a href="@node.Url" class="results-url">@node.Url</a>

                    @if (result.Fields.ContainsKey("title"))
                    {
                        <p class="results-title"><strong>@result["title"]</strong></p>
                    }

                    @if (result.Fields.ContainsKey("bodyText"))
                    {
                        <p>@result["bodyText"].Truncate(250)</p>
                    }
                </section>
                <hr />
            </li>
        }
    </ul> 
}
else
{
    <p>
        There are no results matching your search criteria: 

            @if (!String.IsNullOrWhiteSpace(searchTerm))
            {
                <text>'@searchTerm'</text>
            }
    </p>
}

This is working when I write a word direct in the end of the querystring in the URL (but not yet with special characters like Norwegian ÆØÅ).

Someone who knows how to associate a search box to search in this searchpage with name search-results?

Have found some answers like these, but it not working as intended:

<div class="box hidden-lg hidden-md hidden-sm pull-left">
<div class="container-2">
    <span class="icon"><i class="fa fa-search"></i></span>
    <input type="search" name="keywords" class="form-control" id="search" placeholder="Søk.." onkeydown="Javascript: if (event.keyCode==13) searchRESLT();"/>
</div>

<script>
    function searchRESLT() {window.parent.location} = "/search-results?=" + document.getElementById("search").value;        
</script>
