Simultaneous operations on index - SearchUnit - Forum

I am retrieving a document from an index by its uri. Sometimes I get an exception about running two simultaneous operations on the index. If I wait a minute and try again, it usually works. What do I need to do to avoid this error?

The line of code I'm using is:

Dim TestDoc As Keyoti.SearchEngine.Documents.Document = LibIndex.GetDocument(New Uri("https://domain.com/la1234"))

I anticipate putting this code in a loop where I want to examine one document after another, deciding whether to update it or not.

Thanks, Jim! I just needed to add LibIndex.Close at the end and it worked. I had forgotten that detail. Thanks for your help!
