Trygve Laugstøl commented on LUCY-184:
--------------------------------------
I'd like some way around it at least, because I need to check to see if the
item already is in the index before indexing it (I'm adding extra info to the
document if it's already there).
What are the options for proper ways? A flag that allows the user to search the
index? A separate "index" object that represents the index on disk which can be
queried for existence before creating the searcher?
> Exception is thrown when searching an empty index.
