A colleague of mine put together a search package for use in Umbraco v3.x that was capable of searching for / indexing pdfs, docs, etc. using Lucene. I installed this package and got it working in Umbraco v4.0.0 and tweaked it to my client's satisfaction. Now, however, I've discovered that you can no longer fully delete nodes in the UI!
What happens is you "delete" the node (say a page in the content hierarchy, or a media file) and the icon disappears, but the node name remains, and clicking on it results in a server error "Object reference not set to an instance of an object" (displayed below). Trying to delete it again is no help.
A previous forum article pointed me to discover that it's the version of Lucene that causes the problem (in this case 1.9.0.0). So I swapped out the Lucene.Net.dll file with v. 2.0.0.4. Now I can delete nodes! BUT, I can't use the search anymore! Trying to search the website gives a different server error "Method not found: 'Lucene.Net.Search.Query Lucene.Net.QueryParsers.QueryParser.Parse(System.String, System.String, Lucene.Net.Analysis.Analyzer)'." (see bottom of my post).
Does anyone know of a workaround? I'm trying to avoid having to remove this package, install umbSearch2 (which looks great but is SO new), and then trying to set it up for a client when the project is basically finished and budget expired. But it's a pretty critical bug.
Thanks so much for any help!! Dave

Just an update: I've narrowed it down to see that it's only the deletion of Media files that is affected. So i'm leaving the old dll (1.9.0.0) and telling them not to delete the PDFs. I've added an "excludeFileFromSearch" property to the file media type, which they can set to "yes"
NB: It's not only media files that are affected, by using the old dll you cannot empty the recycle bin, and the embeded search fuction in the UI does not work. I would absolutely advice against using the old dll.
Lucene Search prevents Node Deletion - Any workaround suggestions?

Hi Dave!
I had the same problem as you... I solved it by replacing the dll with 2.0.0.4 and implementing XLSTSearch instead.
After I did that the umbSearch package has been upgraded to work with the new dll.
You could give it a try... http://umbsearch2.codeplex.com/
NB: It's not only media files that are affected, by using the old dll you cannot empty the recycle bin, and the embeded search fuction in the UI does not work. I would absolutely advice against using the old dll.
Have a great summer!
