For example:
I would like to create a document that contains the following fields:
Title
Content
Text1
Text2
…
TextN
But each text have sub fields like Text1_type, Text1_color and so on… can
we create a tree of fields or s
Thank you Itamar.

It turns out my problem was user inflicted data changing, I wasn't finding
what I was looking for because my document manager changed things and
removed files it turns out.
I ended up generating an example program to demonstrate the problem I
thought I had, so I'm going to post it for posterity,
t to be the original document and 3 references from other
documents.
Thanks,

I think, I don't undestand your question.
- IndexSearcher doesn't have a method like "ReOpen"
- IndexWriter/IndexModifier doesn't have a method like "Dispose"
Why don't you use your IndexReader per server like this:
if(!indexReader.IsC
.)

Why do you use IndexModifier? It is deprecated and has a terrible

As you mentioned previously rather than add spacing tokens such as 'xx' between
