In answer to my own question you do not need to handle the other fields separately, however you will get conflicts if you are adding fields so you need to ensure you give them another name, in my case i had field alias duration so i added it as __duration as it was already in as duration.

Hi Ismail,

This is exactly what I need to do too.

How did you get on, do you possibly have any code you could share?

Many thanks

Rich

Hi Ismail,

Thanks alot, I'll let you know how I get on.

Cheers

Rich

I've got the Indexer event wired in, many thanks Ismail/Aaron/Shannon.

Ismail, I think what you're doing is more complex than my issue as you have mulitiple pickers on the same doc type. 

I only have one so in theory I assume I need to split each csv into it's own index.

<attributePicker><![CDATA[1057,1058,1060]]></attributePicker>

And then I'll be able to use some type of "and" criteria to work out id this the search for 1057 and 1060 matches?

Would be good if I can confirm I'm going down the correct path...

Cheers

Rich

Gents,

Just a quick question about the ExamineEvents class (posted above)... After you add it to your project (UmbracoExtensions in my case) do you need to do any change to the ExamineSettings.config or to the ExamineIndex.config? I am using this class to solve a very similar issue (just like the original post), although, after all the changes to the  (my) DocumentAlias, properties, etc... it didn't work out for me. And I can't seem debug it as well...

        private const string WoiIndexer = "TheIndex";
        private readonly List<string> DocumentTypeAlias = new List<string> { "ProjectOverview", "ProjectPage" };
        private readonly List<string> _ultimatePickerAliases = new List<string> { "LeftBlocks", "MiddleBlocks", "RightBlocks" };

        private const string NumericProperties = "LeftBlocks,MiddleBlocks,RightBlocks";

Hope to hear back from you soon.

Cheers,

Carlos

 

Hi Carlos,

Which version of Examine are you running?

Rich

Lucene.net.dll > File version: 2.9.2.1

UmbracoExamine.dll > File version: 0.9.2.0

Hi,

I have the code above working with (shipped with Umbraco 4.5.2)

Lucene.net.dll > File version: 2.9.2.2

UmbracoExamine.dll > File version: 0.9.2.2

Not sure if this makes a difference.

What is your exact problem, does the project not compile or are the indexes not being added?

Rich

 

Hi Rich,

Everything compiles great, although, when I check the Index (using Luke) I don't see the __LeftBlocks, etc (...) fields. I would expect them to be generated as well. Like I told before, I can't debug the class also. Therefore, I am not really sure if this custom UmbracoExamie event handler is being fired up.

Cheers,

Carlos

Hi Carlos,

Two things I can suggest.

One is to make sure you are referencing the correct indexer from the ExamineSettings.Config file (I made this mistake)

  private const string WoiIndexer = "TheIndex";

Second, add a debug to the log to see if the event is getting fired (you'll need to reference using umbraco.BusinessLogic;)

  Log.Add(LogTypes.Notify, -1, "We are watching yooou from examine event");

I couldn't get debugging to work either (I didn't try too hard), so I just used the log to debug as above.

Best of luck

Rich

 

Hi Rich,

That was it... I was referencing my IndexSet not the Indexer. It works now!

Thank you for your quick help!

Cheers,

Carlos

Ismail,

After you've added the special indexes for MNTP in the GatheringNodeData event, how & when do you remove them?

 

Say if I deselect a value from a MNTP field surely I have to remove the index?

Rich

 

Yeah it'll be updated. It runs off the Umbraco XML so if that changes then the index should change.

Hey - following worked for me, had a problem as we needed to query the ParentID on Media objects.
ParentID does not appear to be an attribute of the actual media item, so simple adding this to the ExamineIndex.config did not work.
Seems you have to get the containing (I guess is the right word?) node for the Media item, and then stuff that into your index as a new fields:

       private const string MAGAZINE_INDEXER_NAME = "MagazineIndexer";

     public UmbracoExamineEvents()
     {
         var indexer = ExamineManager.Instance.IndexProviderCollection[MAGAZINE_INDEXER_NAME];
         indexer.GatheringNodeData += MagazineIndexer_OnGatheringNodeData;
     }

       /// <summary>
       /// Handles the OnGatheringNodeData event of the MagazineIndexer.
     /// </summary>
      /// <param name="sender">The source of the event.</param>
     /// <param name="e">The <see cref="Examine.IndexingNodeDataEventArgs"/> instance containing the event data.</param>
     void MagazineIndexer_OnGatheringNodeData(object sender, IndexingNodeDataEventArgs e)
      {
         if (e.IndexType != IndexTypes.Media)
              return;

         e.Fields.Add("_parentID", e.Node.Attribute("parentID").Value);
        }

Hi

I know its been a while since this original post but I am now do something similar to this where I can access properties of a node on the GatheringNodeData event but rather than using the umbraco.presentation.nodeFactory, I am now using the umbraco.NodeFactory  ....

private void IndexShadowProduct(IndexingNodeDataEventArgs e, Node node)
        {
            string origNodeID = e.Fields["umbracoInternalRedirectId"].ToString();

            if (!string.IsNullOrEmpty(origNodeID))
            {
                Node origNode = new Node(int.Parse(origNodeID));
                e.Fields["bodyText"] = origNode.GetProperty("bodyText").Value;
            }

        }

However, I can get a handle on the property but the Value is throwing an exception:

'((new System.Collections.Generic.Mscorlib_CollectionDebugView(origNode.PropertiesAsList)).Items[0]).Value' threw an exception of type 'System.NullReferenceException'

Any ideas? Thanks in advance

Marie

For the hell of me I couldn’t get this to work. I could see the index happening and the fields getting loaded with the “__”. But could not retrieve the information with a search.

 

Then I went and removed the fields instead of adding a new “__” and replaced the values with the retrieved value. Then it worked. What was I missing here. Have a look at the data below and look at the country field If I searched for 1161 I got information back from examine if I searh for "South Africa" I there were no returns.

Why couldnt I retrive any info  with the pre-value with a double underscore 

 

if (propertyValue != string.Empty)

                        {

                            if (propertyValue.Contains(","))

                            {

                                string[] propValues = propertyValue.Split(new[] { ',' });

                                var sbConcatValue = new StringBuilder();

                                foreach (var propValue in propValues)

                                {

                                    sbConcatValue.Append(GetFieldValue(e, propValue, ultimateAlias));

                                    sbConcatValue.Append(",");

                                }

                                e.Fields.Remove(ultimateAlias); 

                                e.Fields.Add(ultimateAlias, sbConcatValue.ToString().TrimEnd(','));

 

                            }

                            else

                            {

                                e.Fields.Remove(ultimateAlias);

                                e.Fields.Add(ultimateAlias, GetFieldValue(e, propertyValue, ultimateAlias));

                            }

                        }
