Hello, I'm working on Search Results Pagination but i couldn't define the Search Term to use it in the pagination, here's my code;

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using System.Web.Mvc.Html
@using Umbraco.Web
@using UmbracoExamine
@using Examine.LuceneEngine.SearchCriteria;
@using Examine.LuceneEngine;
@using Examine.LuceneEngine.Providers;
@{
    Layout = "Master.cshtml";
    string  term ="productName:" + Request.QueryString["searchTerm"]  + "* productDes:"+ Request.QueryString["searchTerm"]  +"*"    ;
    //retrieve current page from query string
    int currentPage = 1;
    if (!String.IsNullOrEmpty(Request.QueryString["page"]))
    {
        int.TryParse(Request.QueryString["page"], out currentPage);
    }

    var noresults = false;
    //container for the searcher
    Examine.Providers.BaseSearchProvider searcher = null;
    //container for the results
    ISearchResults searchResults = null;
    //number of results
    var resultsCount = 0;
    //required results per page
    var pageSize = 10;
    if (Model.Content.HasValue("numberOfItemsPerPage"))
    {
        pageSize = Model.Content.GetPropertyValue<int>("numberOfItemsPerPage");
    }

}

<div class="container">
    <div class="row">
        <div class="col-md-8">
            <div class="searchedKeyword">
        <span class="amman"></span> <span class="keyword">@term</span>
            </div>
            @{
                if (term != null)
                {

                    //now we need to work out which searcher to use
                    //so we'll switch/case on the filter  parameter in the querystring

                    searcher = ExamineManager.Instance.SearchProviderCollection["productSearcher"];


                    //N.B. The following is REALLY basic but should get you started. It's this area where we could really go to town with Lucene.

                    //create search criteria
                    var searchCriteria = searcher.CreateSearchCriteria();

                    //pass the criteria our search term as a raw query
                    var query = searchCriteria.RawQuery(term);

                    //action a search based on our query
                    searchResults = searcher.Search(query);
                    resultsCount = searchResults.TotalItemCount;
                    if (resultsCount < 1)
                    {
                        noresults = true;
                    }
                }
                else
                {
                    noresults = true;
                }

                if (noresults)
                {
                    <div class="noresults media">
                        <h4>
                                 !
                        </h4>
                        <h5>
                                           .
                        </h5>
                    </div>
                }
                else
                {
                    //number of pages
                    int totalPages = 1;
                    if (resultsCount > pageSize)
                    {
                        totalPages = (int)Math.Ceiling((double)resultsCount / pageSize);

                        if (currentPage > totalPages)
                        {
                            currentPage = totalPages;
                        }
                        else if (currentPage < 1)
                        {
                            currentPage = 1;
                        }

                        <div>
                            @resultsCount results
                        </div>

                        <div>
                            Page @currentPage of @totalPages pages
                        </div>
                    }

                    //iterate the results
                    //we could be clever here using linq queries but I want
                    //to keep it simple, easily readable and understandable
                    //for this exercise
                    foreach (var searchResult in searchResults.Skip((currentPage - 1) * pageSize).Take(pageSize))
                    {
                        @Html.Partial("ListproductItem", new ViewDataDictionary { { "productId", searchResult.Id } })
                    }

                    <nav aria-label="Page navigation">
                        <ul class="pagination">
                            <li class="@(currentPage == 1 ? "disabled" : "")">

                                </a>
                            </li>
                            @for (var i = 1; i <= totalPages; i++)
                            {
                                <li>

                }
            }
        </div>
    </div>
</div>

The URL i'm getting from the code above showing below, which is not correct, (d) is the keyword that i searched for;

domain.com/search-results?searchTerm=productName:d*%20productDes:d*&page=1

And the right URL that i'm seeking as follows:

domain.com/search-results?searchTerm=d&page=1

Thanks indeed!
