Hi *,

don't know if this is the right place to ask but there is something i don't understand. Why is it neccessary to store something in the index. (with STORE.YES)
If i open my lucene index with luke i see the fields with the indexed values. (indexed with StandardAnalyzer)
So i know the words and there positions.
I think it should be possible to get the same informations as if the data was stored in the index. Or are there additional informations stored?
I although noticed the sign in Luke "Restored content only - check for errors". How could there be errors?

I didn't find some information about whats going on behind the scenes, maybe one of you can give me a hint where i missed to read or where to find some better information.

Hi,

you might be able to see the word and position information, but what if you for example use a synonym analyzer which inserts new tokens. How do you restore the original text then. If you want to use projection or for some other reason need the original text you need to use STORE.YES.

if you want a deeper explanation I recommend you talk to the Lucene guys. There is also a document on the Lucene homepage describing the exact index format. I am sure you can learn a lot about the internal workings of the index reading it.

Hope this helps.
