Anyone please suggest what change/config i need to do inorder for the lucene index to work?

I am using umbraco 4.0.3 installation and seeing a folder named "data/_systemUmbracoIndexDontDelete".

i tried UmbracoExamine also, but still not able to get the Lucene Index creation/updattion/refreshing working. 

Please help...!!!

you will receive better help if you provide reasons for problems, not just saying that something is "not working".

The Lucene.Net implementation in 4.0 was prone to getting corrupt quite easily, and it also had many leaks, resulting in it getting very large very quickly.

Examine is the recommended solution, and there is documentation on codeplex on how to set it up.

Thanks Slace. I went through code plex Examine documentation and made required changes to web.config. however i am not seeing lucene index getting created. i made required config changes as follows. could you please check and let me know what i am doing wrong.

In Web.config

====================

<configSections>

<section name="Examine" type="Examine.Config.ExamineSettings, Examine"/>

<section name="ExamineLuceneIndexSets" type="UmbracoExamine.Config.ExamineLuceneIndexes, UmbracoExamine"/>

</configSections>

<Examine configSource="config\ExamineSettings.config"/>

<ExamineLuceneIndexSets configSource="config\ExamineIndex.config"/>

In ExamineIndex.config

========================

<ExamineLuceneIndexSets>

  <IndexSet SetName="Default" IndexPath="~/App_Data/ExamineIndexes/Internal/">

    <IndexAttributeFields>

      <add Name="id" />

      <add Name="nodeName" />

      <add Name="updateDate" />

      <add Name="writerName" />

      <add Name="path" />

      <add Name="nodeTypeAlias" />

      <add Name="parentID" />

    </IndexAttributeFields>

    <IndexUserFields />

    <IncludeNodeTypes>

      <add Name="ProductsDocumentTypes" />

    </IncludeNodeTypes>

    <ExcludeNodeTypes />

  </IndexSet>

ExamineSettings.config

============================

<Examine>

Hello Slace.... Following is the Error message i am getting when i do publish a content node.

Error indexing node: System.MissingMethodException: Method not found: 'Void Lucene.Net.Documents.Document.Add(Lucene.Net.Documents.Field)'.     at umbraco.cms.businesslogic.index.Indexer.IndexNode(Guid ObjectType, Int32 Id, String Text, String UserName, DateTime CreateDate, Hashtable Fields, Boolean Optimize)     at umbraco.cms.businesslogic.web.Document.Index(Boolean Optimze)

What is the version of the Lucene.Net assembly which you are running? Examine is running 2.9.2

Lucene.Net.dll version ---> 2.9.2.1

FYI - i downloaded from codeplex UmbracoExamine and copied to BIN folder of Umbraco4.0.3 instance the UmbracoExamine.dll,  Lucene.Net.dll, Examine.dll. Overwritten the olden version of lucene that was used by umbraco4.0.3 instance (which is Lucene.Net.dll 2.3.1.2)

Please let me know whether i am doing something wrong?

THANKS A LOT SLACE... you helped me by pointing towards umbracoLog table for errors.

umbracoLog table helped to DEBUG the ISSUE till RESOLUTION.

Now i am able to get the Lucene Index updated whenever i am publishing the contents in content tree. Thanks Again.

Bharath,

Would you be so kind as to describe what exactly caused the problem? I'm having a similar problem, but I believe it might be due to the wrong version of the Lucene.net assembly

If you are using Examine you need to use the Lucene.Net release that ships with it, which is Lucene.Net 2.9.2

It will not work with any older version

I was getting the same error while publishing nodes. I'm using a custom branch of 4.0.1, and turns out that with the latest lucene.net dll 2.9.2.1 was causing this error along with the umbsearch2 package. I reverted to 2.0.0.4 and it started working again.

I don't know what umbsearch2 uses, but you should stick with what ever comes in their release package

We had to switch my search package from umbSearch2 to Examine as umbSearch did not have the flexibility that we require on our project, and the very helpful Paul Sterling in the Umbraco support team also recommended it. We're still using umbraco 4.0.1, but I'm having a pretty hard time getting the indices to build.I've read elsewhere that 4.0.3 is not fully supported on the older version of examine. So I went ahead and got the latest version of Examine (Release ver. 54684).

I'm not sure if I should be posting this here instead of starting a new topic ; there's also a similar thread over at  http://our.umbraco.org/forum/developers/extending-umbraco/7732-Umbraco-Examine-Search-Setup?p=1 but Shannon's fix for a bug that occurs in 4.0.3 doesn't work for me.

Here's what I've so far : I built the following dll's from source: Examine.dll, UmbracoExamine.Contrib.dll and UmbracoExamine.dll and copied them over to bin of my site

I added the following configuration in web.config, and published a few nodes. The directory "MediahouseIndexSetTest" does get created in my App_Data when I published a node, but I'm not getting anything in the "index" and "queue" folders. I also tried changing 'runAsync' in my Index Provider from false to true, but nothing came of that.

Is there any obvious error in here? I also tried giving full permission to my Index set folder, to the "creator, network service and admin users".

Check your umbracoLog table and see if there in an event on application state indicating the Examine event handlers are setup.

If they aren't then Examine wont run and you're likely to have errors in the log too.

The only entries in the logComment column are "[UmbracoExamine] Adding examine event handlers for index providers: 0".

Does this mean that the event handlers are not being set up? Wonder why that's happening. Aren't the examine dll's supposed to take care of that automatically? I'm not getting other errors in my table though.

It means that there are no configured providers. Is the config you  listed above in your web.config?

Yes it's in my web.config file. These tags are under the <configuration> tag. I tried including them in seperate source files(like the umbraco 4.5 web.config), but still nothing. Perhaps I should provide a defaultProvide for the index provider?

Thanks for the lead slace! I finally got the indices to build finally after tweaking the web.config file.

Here's the configuration for the providers. I think removing the 'analyzer' attribute did the trick.

<Examine>

    <ExamineIndexProviders>

      <providers>

        <!-- Shows all of the configuration options available -->
        <add name="MediahouseIndexer"
             type="UmbracoExamine.LuceneExamineIndexer, UmbracoExamine"
             indexSet="MediahouseIndexSet"
             runAsync="true"         
           
           />

      </providers>

    </ExamineIndexProviders>


    <ExamineSearchProviders defaultProvider="MediahouseSearcher">
      <providers>

        <!-- Used to show how to create a searcher by naming convensions -->

        <!-- This search provider is used for our test searches -->
        <add name="MediahouseSearcher"
             type="UmbracoExamine.LuceneExamineSearcher, UmbracoExamine"
             indexSet="MediahouseIndexSet"             
               />


      </providers>
    </ExamineSearchProviders>
  </Examine>
  

Actually you disabled the events (enableDefaultEvents=false), that was your problem, you turned off the Umbraco events, so the only way to get data into the index was to manually push it there.

Somebody pleeeease help!

We have a build of Umbraco 4.0.4.2 that's had Examine applied to it. We've got 8 custom indexes setup in the examine settings file and they test and build successfully in classic pipeline mode on IIS6 and IIS7.

If we switch to integrated mode, the folders get created but the queues dont get worked on, it just stops! There's nothing obvious in the umbraco logs to indicate a problem either.

Strangely locally on my Windows 7 PC (IIS7.5) the indexer works fine in integrated mode which is all the more frustrating!

Anyone out there with ANY ideas to indicate where it's going wrong would be much appreciated.

We're using the latest Examine dlls from RC3.

Posting the same question across multiple threads is generally frowned upon, I was replying to you in this thread: http://our.umbraco.org/forum/developers/extending-umbraco/7732-Umbraco-Examine-Search-Setup?p=2

Did you try what I suggested, disabling async and then checking the log table?

is working on a reply...
