Great question.
When gathering data from a backend api, in react here's how you would do it:
const [fetchedData, setFetchedData] = React.useState(null);
function fetchData() {
fetch('http://example.com/movies.json')
.then(response => response.json())
.then(data => setFetchedData(data));
};
// loads data initially on page load
React.useEffect(() => {
fetchData()
}, [])
//use this function to tie to an "onChange" or "onClick" event when submitting the values.
function filterData(inputValue) {
if(inputValue === "") return;
const filteredData = fetchedData.filter((value) => {
return value.SEARCH_INDEX_VALUE_HERE >= inputValue
}
return filteredData;
}
You can find a good description from here
This is given that the data returned is an array of objects, and the the SEARCH_INDEX_VALUE_HERE is whatever column key that is provided to the data you're filtering. In your case, it would be the "Search value" field I believe.

You can use filter method of JavaScript like this.
var filteredData = data.filter(function (item)
{
return item.Search_volume >=20000;
}
);
