Im using two check boxes one called eftervaern and one called kriminalitet. If one of the two checkbox's is not checked the script won't run. Is it not possible to use a variable in searchCriteria that potentially could be equal null? Is there a way around this? im lost for ideas atm.

@using Examine

@using Examine.SearchCriteria

@{

    //Get the values posted from the form

var eftervaern = Request.QueryString["eftervaern"];

var kriminalitet = Request.QueryString["kriminalitet"];

    var searcher = ExamineManager.Instance.SearchProviderCollection["RazorSiteSearcher"];

    var searchCriteria = searcher.CreateSearchCriteria(BooleanOperation.Or);

var query = searchCriteria.Field("eftervaern", @eftervaern).Or().Field("kriminalitet", @kriminalitet).Compile();

    var searchResults   = searcher.Search(query);

    var noResults       = searchResults.Count();

    <ul class="search-results">

        @foreach (var result in searchResults)

        {

            <li>

                <a href="@umbraco.library.NiceUrl(result.Id)">@result.Fields["nodeName"]</a>

            </li>

        }

    </ul>

}
