You need to exclude NEW MATERIALS from the
script code array:

function myFunctionmat() {
                                    var input, filter, section, aside, a, i;
                                    input = document.getElementById("mySearch");
                                    filter = input.value.toUpperCase();
                                    section = document.getElementById("materials");
                                    aside = section.getElementsByTagName("aside");
                                    for (i = 0; i < aside.length; i++) {
                                        a = aside[i].getElementsByTagName("a")[0];
                                        if (a.innerHTML.toUpperCase().indexOf(filter) > -1) {
                                            aside[i].style.display = "";
                                        } else {
                                            aside[i].style.display = "none";
                                        }
                                    }
                                }

                                function myFunctionmat() {
                                    var input, filter, section, aside, a, i;
                                    input = document.getElementById("mySearch");
                                    filter = input.value.toUpperCase();
                                    section = document.getElementById("materials");
                                    aside = section.getElementsByTagName("aside");
                                    for (i = 0; i < aside.length; i++) {
                                        a = aside[i].getElementsByTagName("p")[0];
                                        if (a.innerHTML.toUpperCase().indexOf(filter) > -1) {
                                            aside[i].style.display = "";
                                        } else {
                                            aside[i].style.display = "none";
                                        }
                                    }
                                }
