Re: [FT] FTIgnoreOption

Andrew,

As I said earlier, there are 2 semantics:

- The one used right now in the draft is the simple one that you're
  proposing here:
  >Also I think it might be clearer if:
  >(nodeA ftcontains "some phrase" without content ./nodeB)
  >or
  >(nodeA ftcontains "word" without content ./nodeB)
  >simply requires the children nodeB's (and all its descendants) be pruned 
  >from nodeA before the keywords are searched.

  which means that you're correct here (thanks!):
  >According to FT Specification 3.2.8, the example query:
  >/book[@number="1"] ftcontains "Testing" without content .//title
  >"returns false because "Testing" does not occur without the title 
  >element whose content is ignored."
  >But you suggested that search on a single word is no-op for FTIgnoreOption.
  >Would it be inconsistent?
  

- The one explained in my first response.


Although only the first one is used in the draft, both are under
discussion.


Thanks,
Sihem
