Subject Re: Indexing books, chapters and pages
Date Tue, 01 Mar 2016 16:30:47 GMT
 From the top of my head - probably does not solve problem completely, 
but may trigger brainstorming: Index chapters and include page break 
tokens. Use highlighting to return matches and make sure fragment size 
is large enough to get page break token. In such scenario you should use 
slop for phrase searches...

More I write it, less I like it, but will not delete...
