I need help - please

Can you send a link to your page? Easiest route is to probably just clear the storage and set the search to null after the function. See below in bold

 
import {local} from 'wix-storage';
import wixLocation from 'wix-location';

$w.onReady(function () {

});

export function searchButton_click() {
let word = $w("#searchBar").value;
    local.setItem("searchWord", word);
wixLocation.to(`/search-results`);
}
**Results Page Code **
import {local} from 'wix-storage'; 
import wixData from 'wix-data';   

$w.onReady(function () {  

var sameWord = local.getItem("searchWord");     
$w("#searchBar").value = sameWord;     
$w("#searchBar").placeholder = sameWord;     
$w('#dataset1').onReady(function () {         
search();     
}); 
});   

export function searchButton_click() {     
search(); }   function search() {     
wixData.query('Stores/Products')    
.contains('name', $w("#searchBar").value)
.or(wixData.query('Stores/Products')
.eq('price', $w("#searchBar").value))         
.find()        
.then(res => {   
$w('#repeater1').data = res.items;
 local.clear(); 
 $w("#searchBar").value = null;
}); 
}
