Examine Search: How to query nodes of specific parent
Hi to all, I'm trying to find a way to search nodes of a specific parent.

I read the very helpful Shazwazza examine documentation and I think that I must search in the field "__Path" that have a specific Node Id.

In the documentation I found this code from which I think I could start
```
var exactfilter = exactcriteria.Field("__Path", "-1,123,456,789".Escape());
```
But after some tests, I still don't find the right solution.

Can anyone help me?

Thank you for the support

Hi You need to add a searchable path to the examine index which essentially takes the path and replaces the commas with spaces. Here is a link to some documentation which has an example for you.

Hi...sorry for delay to answer.

I try some solutions, including that you suggest, but I resolved using this simple code:

if(ExamineManager.Instance.TryGetIndex("InternalIndex", out var index))
{
    var Searcher = index.GetSearcher();
    var textFields = new[] { "nodeName", "title",  "bodyText" };
    var results = ((Searcher.CreateQuery()
                              .GroupedOr(textFields, searchTerm)
                              .OrderByDescending(new SortableField("date"))
                              .Execute())
                              .Where(w => w["__IndexType"] == "content" &&  
                                          w["__NodeTypeAlias"] == "repository" &&
                                          w["__Path"].Contains("16602") &&
                                          w["__Published"] == "y" &&
                                          w["umbracoNaviHide"] == "0"));
    ...
    ...
}

Just note that this won't work if you have more than 500 results as Execute() by default limit to 500 results and that the LINQ query is more expensive.

You can add a searchPath like this in Vendr demo store

https://github.com/vendrhub/vendr-demo-store/blob/a976c4eafefcd3e92acbc9d65d4c73b529746e36/src/Vendr.DemoStore/Composing/DemoStoreComponent.cs#L83-L86

and then search this field, something like the following:
```
query.GroupedOr(new [] { "searchPath" }, new [] { "16602" } );
```

Hi Bjarne,

thank you for the support.

I added the search path field like Vendr demo store...but I already have the GroupedOr(textFields, searchTerm) in my query

How I must change the code to include your change?

Hi. I tried to add a piece of your code but VS complains that there is no Add() method taking 2 arguments..
```
// Create searchable path
if (e.ValueSet.Values.ContainsKey("path"))
{
   e.ValueSet.Add("searchPath", e.ValueSet.GetValue("path").ToString().Replace(',', ' '));
}
```

Hi Adriano

Based on your query before, you can filter the results as part of the Examine query something like the following:

var query = searcher.CreateQuery("content")
        .NodeTypeAlias("repository")
        .And()
        .Field("searchPath", "16602")
        .And()
        .Field("__Published", "y")
        .And()
        .Field("umbracoNaviHide", "0")
        .And()
        .GroupedOr(textFields, searchTerm)
        .Execute();

var results = query
        .OrderByDescending(new SortableField("date"))
        .Execute();

To search path you may need to create a searchPath field: https://our.umbraco.com/documentation/reference/searching/examine/examine-events

Hi Bjarne,

I tried and all function properly.

Only for info...to work correctly I had to write the query like that:

 var results = Searcher.CreateQuery("content")
              .Field("__Published", "y")
              .And()
              .Field("umbracoNaviHide", "0")
              .And()
              .NodeTypeAlias("repository")
              .And()
              .Field("searchPath", Model.Id.ToString())
              .And()
              .GroupedOr(textFields, searchTerm)
              .OrderBy(new SortableField("nodeName"))
              .Execute();
