> 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.
