blogspot pagination: how to remove older posts tex

When I access a blogspot label, the page always show older posts text. If I use max-result it show the line numbers but I feel it's not a SEO friendly url with max-result suffix, the phrase /search/label is bad enough for SEO.

I want to know how to remove older posts text and replace it with the line numbers when accessing labels. Like this

I would appreciate it if someone could help me solve this problem!

Thanks very much!

Here is the code

var perPage = 12;
 var numPages=5;
 var firstText ='Trang đầu';
 var lastText ='Trang cuối';
 var prevText ='Trang trước';
 var nextText ='Trang kế';
 var urlactivepage=location.href;
 var home_page="/";

if (typeof firstText == "undefined") firstText = "First";
if (typeof lastText == "undefined") lastText = "Last";
var noPage;
var currentPage;
var currentPageNo;
var postLabel;
pagecurrentg();

function looppagecurrentg(pageInfo) {
    var html = '';
    pageNumber = parseInt(numPages / 2);
    if (pageNumber == numPages - pageNumber) {
        numPages = pageNumber * 2 + 1
    }
    pageStart = currentPageNo - pageNumber;
    if (pageStart < 1) pageStart = 1;
    lastPageNo = parseInt(pageInfo / perPage) + 1;
    if (lastPageNo - 1 == pageInfo / perPage) lastPageNo = lastPageNo - 1;
    pageEnd = pageStart + numPages - 1;
    if (pageEnd > lastPageNo) pageEnd = lastPageNo;
    html += "<span class='showpageOf'>Page " + currentPageNo + ' of ' + lastPageNo + "</span>";
    var prevNumber = parseInt(currentPageNo) - 1;
    if (currentPageNo > 1) {
        if (currentPage == "page") {
            html += '<span class="showpage firstpage"><a href="' + home_page + '">' + firstText + '</a></span>'

                currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)

            document.write("<script src=\"" + home_page + "feeds/posts/summary?max-results=1&alt=json-in-script&callback=totalcountdata\"><\/script>")

function finddatepost(root) {
    post = root.feed.entry[0];
    var timestamp1 = post.published.$t.substring(0, 19) + post.published.$t.substring(23, 29);
    var timestamp = encodeURIComponent(timestamp1);
    if (currentPage == "page") {
        var pAddress = "/search?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
    } else {
        var pAddress = "/search/label/" + postLabel + "?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
    }
    location.href = pAddress
}

I edited the script from:

// old version
if(thisUrl.indexOf("/search/label/") != -1) {
  if(thisUrl.indexOf("?updated-max") != -1) {
    postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?updated-max"))
  } else {
    postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?&max"))
  }
}

To:

if(thisUrl.indexOf("/search/label/") != -1) {
  if(thisUrl.indexOf(/\?[a-z-]+=/g) != -1) {
    postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf(/\?[a-z-]+=/g))
  } else {
    postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.match(/\?|#|&|$/).index)
  }
}
