Umbraco Tags with spaces on a multi language site?
# help-with-umbracoj
JigitalCharlie
10/16/2023, 3:57 PMI have an interesting problem. I have a tagging system and the content editor would like to add spaces in the tag I.E 'News and Views' and then another tag 'Health and Fitness'
In the Index this is stored as News and Views, Health and Fitness so i cannot do a .exact on the string when searching?
Also if i try to create my own on index field i need the language variation which i cannot get access to from within the IComponent.
Any ideas?

csharp
public void Configure(string? name, LuceneDirectoryIndexOptions options)
{
switch (name)
{
//NB you need to rebuild the examine index for these changes to take effect
case Constants.UmbracoIndexes.ExternalIndexName:
options.Analyzer = new CultureInvariantStandardAnalyzer(CharArraySet.EMPTY_SET);
...
}

tag_0 : News and Views : type:raw
tag_1 : Health and Fitness : type:raw
And then you can use string.Escape() to phrase match against the raw field ??

10/17/2023, 10:47 AMsome documentation here.. https://docs.umbraco.com/umbraco-cms/reference/searching/examine/indexing

10/17/2023, 10:52 AMQuick look at searchExtensions.. and think it introduces a listValueType.. (used for path) perhaps you'd have mileage with your tag property by setting in your custom indexoptions?

csharp
public void Configure(string name, LuceneDirectoryIndexOptions options)
{
options.IndexValueTypesFactory = new Dictionary<string, IFieldValueTypeFactory>
{
{ "json", new DelegateFieldValueTypeFactory(fieldName => new JsonValueType(fieldName, _loggerFactory)) },
{ "list", new DelegateFieldValueTypeFactory(fieldName => new ListValueType(fieldName, _loggerFactory)) },
{ "picker", new DelegateFieldValueTypeFactory(fieldName => new PickerValueType(fieldName, _loggerFactory)) },
{ "udi", new DelegateFieldValueTypeFactory(fieldName => new UdiValueType(fieldName, _loggerFactory)) },
};
options.FieldDefinitions.AddOrUpdate(new FieldDefinition("path", "list"));
options.FieldDefinitions.AddOrUpdate(new FieldDefinition("createDate", "date"));
options.FieldDefinitions.AddOrUpdate(new FieldDefinition("updateDate", "date"));
}Mike Chambers
10/17/2023, 11:01 AMlooking at something completely different.. and came across..
https://github.com/umbraco/Umbraco-CMS/blob/contrib/src/Umbraco.Core/PropertyEditors/TagPropertyIndexValueFactory.cs#L17 .. might mean in later version of umb you already get the separated out fields for tags?

11/22/2023, 10:10 AMHi @Mike Chambers - When you change the Analyzer for your index, did it update the table in the backoffice? I'm doing that on a site but when I check the Analyzer in the Examine table, it still shows "StandardAnalyzer"

11/22/2023, 10:32 AMyes, not sure if that also needs you to have done an index rebuild..

11/22/2023, 10:44 AMI tried that, but it's not changing for me... Thanks. Just highlights that there's a bug somewhere in my code/Umbraco version!
