> All search result data we display in search results has to be explicitly 
> Entity.encoded outputing in search.jsp ( title, url, etc.) except Summaries.  
> Its already Entity.encoded.  This is fine when outputing HTML but it gets in 
> the way when outputing otherwise -- as xml for example.  I'd suggest we not 
> make any presumption about how search results are used.
> The problem becomes especially acute when the text language is other than 
> english.

> I'd suggest that Summary#toString() become Summary#toEntityEncodedString() 
> and that toString return raw aggregation of Fragments.  Would likely require 
> adding methods to the HitSummarizer interface so can ask for either raw text 
> or entity encoded with addition to NutchBean so can ask for either.  Or, 
> better I'd suggest is that Summarizer never return Entity.encoded text.  Let 
> that happen in search.jsp (I can make patch to do the latter if its amenable).
