Chris Harris updated SOLR-42:
-----------------------------
Attachment: HtmlStripReaderTestXmlProcessing.patch
Updating test case to reflect the fact that offset info still gets screwed up
in the XML processing instruction case even if there are no XML elements in the
source XML
> Highlighting problems with HTMLStripWhitespaceTokenizerFactory

> 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.
