Marvin Humphrey updated LUCY-182:
---------------------------------
Attachment: LUCY-182.patch
The problem arises because Highlighter_highlight_excerpt is being passed the
wrong array of Spans. It is getting the raw Spans produced by the Compiler
object, which may contain overlapping Spans. It should instead be using the
"flattened" array of Spans produced by the HeatMap, which has no overlaps and
was in fact purpose-built for this situation.

> I stumbled onto this one when searching for [business to business].
> Source <TITLE>: ...Companies, Products, Trade Leads, Business Marketplace
> 'to' is a stopword which is ignored - no problem.
> So the query then becomes [business business]. The highlighter then produces:
> ...Companies, Products, Trade Leads, <strong>Business</strong>
> <strong>Marketp</strong>lace
> I then spent some time chasing my tail trying to reduce things down to
> a small reproducible unit, and finally decided to try searching for
> any duplicate [wordX wordX], and sure enough it's reproducible with
> all my indexes.
