endOffset, startOffset of Token

Are the endOffset, startOffset fields of a Token used in 
proximity search and phrase search.

My problem is that I tried my own TokenStream and may have
messed up the offsets. What are the restrictions for a phrase
search to work? Do the offsets of tokens have to be exactly
adjacent?

  Thanks,
  Harald.

No.  There are not used by indexing or search.  Their intent is only to 
aid the extraction of matching text snippets when displaying results.
