There is definitely still an issue w/ the HTMLStripReader in some
circumstances, working on a test now.

Red herring. The problem I was seeing is due to some tags that are valid
syntax for my text are being stripped. I think this patch can go ahead,
although it might be useful to keep certain tags (i.e. a set of tags)

> Key: SOLR-42
> URL: https://issues.apache.org/jira/browse/SOLR-42
> Project: Solr
> Issue Type: Bug
> Components: highlighter
> Reporter: Andrew May
> Assignee: Grant Ingersoll
> Priority: Minor
> Attachments: htmlStripReaderTest.html, HTMLStripReaderTest.java,
> SOLR-42.patch
>
>
> Indexing content that contains HTML markup, causes problems with highlighting
> if the HTMLStripWhitespaceTokenizerFactory is used (to prevent the tag names
> from being searchable).
> Example title field:
> <SUP>40</SUP>Ar/<SUP>39</SUP>Ar laserprobe dating of mylonitic fabrics in a
> polyorogenic terrane of NW Iberia
> Searching for title:fabrics with highlighting on, the highlighted version has
> the <em> tags in the wrong place - 22 characters to the left of where they
> should be (i.e. the sum of the lengths of the tags).
> Response from Yonik on the solr-user mailing-list:
> HTMLStripWhitespaceTokenizerFactory works in two phases...
> HTMLStripReader removes the HTML and passes the result to
> WhitespaceTokenizer... at that point, Tokens are generated, but the
> offsets will correspond to the text after HTML removal, not before.
> I did it this way so that HTMLStripReader could go before any
> tokenizer (like StandardTokenizer).
> Can you open a JIRA bug for this? The fix would be a special version
> of HTMLStripReader integrated with a WhitespaceTokenizer to keep
> offsets correct.
