segments, whats used when searching?

[EM]

I'm trying to grasp something here, I need a quick confirmation about the
following, a yes/no would suffice:

When searching and generating summaries, tomcat uses only:
1. <segment>/index
2. <segment>/parse_text

When retrieving the "cached" copy of the document, tomcat uses:
1. <segment>/parse_data

Are <segment>/fetcher and <segment>/context used during the searching stage?
