Would you like to not index the files, or just not want the files to be shown in the public search results ?

are you using Find (Search & Navigation)

Thanks Quan.  Yes, we are using Search & Nav.

I can't think of why any of our uploaded files need to be indexed, but either way should achieve the immediate goal.

You can add a convention to prevent those files from being indexed. P/s you should update to latest version of Form if you haven't already

Adding a convention is one thing I was looking at, but how do I target files specifically uploaded via the FileUpload element?

Re: EPiServer.Forms, I am on the latest

A quick way to do it - not bulletproof but probably good enough, is check a file of type IContentMedia if it belongs to folder named EPiServer.Forms.Constants.FileUploadFolderName before indexing 

Quan, I'm making a guess you are referring to something like:

ContentIndexer.Instance.Conventions.ForInstancesOf<IContentMedia>().ShouldIndex(x => x.???)

If so, how would I check for it's containing folder?

If not, can you share more info on how to do this?

Yes, you can get its parent, something like this (pseudo code of course) 

x =>  {

var parent = _contentRepo.Get<ContentFolder>(x.ParentLink);

if (parent.Name == EPiServer.Forms.Constants.FileUploadFolderName) { return false ; }

return true;

}

I'll try this.  I'll add this to our SearchInitialization module, which I assume is used during indexing.  I am wondering though... could this approach have a significant impact on performance of indexing?  I suppose I needn't be too concerned about the overnight job, but wanted to check.

it depends on how many files you have - and under how many folders. if you have many files but only a few folders it would not take a lot of time (Get<T> is cached )

If we take a step back, this should not happen. Can you please reach out to support at support@optimizely.com, refer to this thread and cc me (quan.mai [at] optimizely.com ) ? we are interested in looking into this. thank you
