Hi,I'm having trouble starting up Umbraco with a configuration that uses a simpleDataIndexer. The error on starting up is:Parser Error Message: Value cannot be null.Parameter name: typeThe line in error is:<add name="CustomIndexer" type="Examine.LuceneEngine.Providers.SimpleDataIndexer, Examine" dataService="xxxDataService, xxxSearch" indexTypes="CustomData" />I've followed the advice on:http://our.umbraco.org/forum/developers/extending-umbraco/15786-Examine-SimpleDataIndexer-problemWith no luck. Although I can see the error seems to suggest the type cannot be found, the class library is definitely there and namespace is correct. I'm not sure where indexType is meant to be defined ? so myabe I'm missing something there ?Having trouble finding documentation about this, and feel like I've reached a bit of a dead end.Any help would be great,Thanks in advance,RegardsPeter
I ended up using Lucene API directly. My requirements where reasonably straight forward so it worked out much quicker than trying to figure out why the SimpleDataIndexer wasnt working. The Lucene API is reasonably straight forward and there is lots of documentation and examples to follow.
Just a note on this... was banging my head on this as well. Turns out you need to create a compiled class (DLL) and not use app_code as that stuffs with the namespace. I put all my code into a DLL and it works a treat...
What Karl Kopp said! I ran into this a year ago or so when I was doing some work with Custom Index sets. As long as it's in a DLL rather than App_Code it should work fine :)
I found a simple solution for those who experience this problem in the future. There is no need to move your code in to a DLL. You just need to change the dataService parameter in the ExamineSettings.config for your SimpleDataIndexer to reference App_Code like below.
Examine SimpleDataIndexer will not initialize

Hi,
I'm having trouble starting up Umbraco with a configuration that uses a simpleDataIndexer. The error on starting up is:
Parser Error Message: Value cannot be null.
Parameter name: type
The line in error is:
<add name="CustomIndexer" type="Examine.LuceneEngine.Providers.SimpleDataIndexer, Examine" dataService="xxxDataService, xxxSearch" indexTypes="CustomData" />

Same error here, did you fix it?
Hi Edwin,
No. I'm afraid I didnt.
I ended up using Lucene API directly. My requirements where reasonably straight forward so it worked out much quicker than trying to figure out why the SimpleDataIndexer wasnt working. The Lucene API is reasonably straight forward and there is lots of documentation and examples to follow.
Let me know if I can help in any other way,
Regards
Peter
Thanks! you try that.

I always work with compiled project but it didn't work with me (7.1.1). I now use Lucene direct and that works.
The error is caused by the method in the dataService tag returning the wrong type. Happy to share code if it helps anyone?
@Edwin - keen to get some more details on how you did it with the Lucene API?? Love to get some info...
It's pretty easy.. this was a good start http://www.aspfree.com/c/a/braindump/working-with-lucene-net/

<add="CustomIndexer"type="Examine.LuceneEngine.Providers.SimpleDataIndexer, Examine"dataService="xxxDataService, App_Code" indexTypes="CustomData" indexSet="CustomIndexer"/>Thanks Josh - can confirm this works a treat :)
@Karl - You're welcome. I'm glad I could help.
is working on a reply...
