search for a node through the data values of the node itself

how can i lookup a node by the values of that node and focus it by expanding all parents and siblings

If you have a search box, roughly you need to do the following:

1. Listen to seach input change event
2. In the handler function, get chart data
3. Find all nodes which match your search and set _expanded to it (you can also use _selected)
4. rerender graph

Rough implementation

function handleSearch(searchText) {
  const data = chart.data();
  data.forEach(d => {
    if (d.nameOrOtherProperty.includes(searchText)) {
      d._expanded = true;  // if you just want expand
      d._selected = true;    // if you also want it to be selected, not remember if it's possible to select multiple nodes so not sure if this will work
    }
  })

  chart.data(data).render()

}

1 node {value 10}
.... 2 node {value 20}
..... 3 node {value 30}
........ 4 node {value 40 }
5 node {value 50}
.... 6 node {value 60}

if i want to search value 30 (passed value at my function) i want expand parents at the end my node.
it's possible to do this?

Yes, you can use following code. Probably not precise, but it will give you directions

function handleSearch(searchText) {
  const data = chart.data();
  data.forEach(d => {
    if (d.value.includes(searchText)) {
      d._expanded = true;  // if you just want expand
      d._selected = true;    // if you also want it to be selected, not remember if it's possible to select multiple nodes so not sure if this will work
    }
  })

  chart.data(data).render()

}
