Hi Vitaly,

Thanks for this, I'll give it a go.

Cheers

Hi Paul,

As for examine solution I would suggest you to manually extend the index by handling BaseIndexProvider.GatheringNodeData event. Sample implementation of the event handler could be the following (assume there are stored location tags in the Umbraco content and examine configured to index that property)

private void OnGatheringNodeData(object sender, IndexingNodeDataEventArgs e)
{
    // logging stuff
    LogHelper.Info<IndexExtender>("Extending index node: IndexType={0}, Indexer={1}, NodeId={2}", () => e.IndexType, () => _indexer.Name, () => e.NodeId);
    try
    {
        // retrieve json array stored in the examine index field, which is configurated to index content property of 'uTaxonomy' 
        var locationsJson = e.Fields["locations"];
        // deserialize raw json array to the list of strings
        var locationIds = JsonConvert.DeserializeObject<List<string>>(locationsJson);
        var locationNames = new List<string>();
        // iterate over the identifiers to retrieve taxonomy names
        foreach(var locId in locationIds)
        {
            // "Locations Taxonomy" - Umbraco uTaxonomy data type
            Taxonomy location  = TaxonomyService.GetTaxonomyById("Locations Taxonomy", locId);
            locationNames.Add(location.ToString());
        }
        // produce a string containing location names separated by space to make it available for searching and put the string into the new examine field
        e.Fields["locations_searcheable"] = string.Join(" ", locationNames);

        // for now its possible to search by location name against "locations_searcheable" examine field 
    }
    catch (Exception ex)
    {
        // logging stuff
        LogHelper.Error<IndexExtender>(string.Format("Extending index node failed: IndexType={0}, Indexer={1}, NodeId={2}", e.IndexType, _indexer.Name, e.NodeId), ex);   
    }
}

Hi Artyom,

Thanks for this, can you tell me what the namespace is for IndexExtender from the line "LogHelper.Info

Thanks

Hello again and Happy new year.

I've got an issue that I'm trying to work out, basically the GetTaxonomyTree doesn't seem to show the child items.

Here's my code/your code:-

var result = new List<Taxonomy>();
        var dataTypeService = UmbracoContext.Current.Application.Services.DataTypeService;
        var dataType = dataTypeService.GetDataTypeDefinitionByName("Areas");
        if (dataType != null)
        {
            var valueList = dataTypeService.GetPreValuesCollectionByDataTypeId(dataType.Id);
            if (valueList != null)
            {
                var value = valueList.PreValuesAsDictionary.FirstOrDefault(x => x.Key == "tree");
                if (value.Value != null)
                {
                    result = JsonConvert.DeserializeObject<List<Taxonomy>>(value.Value.Value);

                    foreach (var itm in result) {
                    Response.Write(itm.Item.Id + "<br/>");  
                    }
                }
            }
        }

This only outputs the top level items in the list - how do we get the children to show?

Many Thanks

Paul

Thank Vitaly, this is great. I think I've managed to clear up all my code issues now.

Many thanks for all your help.
