Anders Melchiorsen updated SOLR-1394:
-------------------------------------

    Attachment: hex-entity.patch

I did not even test that this patch compiles, but it should show what I had in 
mind.

I will not have time to work on this during the weekend.

> The Solr HTML stripper is replacing any removed HTML with whitespace. This is 
> to keep offsets correct for highlighting.
> However, as was already pointed out in SOLR-42, this means that any token 
> containing an HTML entity will be split into several tokens. That makes the 
> HTML stripper completely unreliable for international text (and any text is 
> potentially interantional).
> The current code is actually deficient for BOTH highlighting and indexing, 
> where the previous incarnation (that did not insert spaces) only had problems 
> with highlighting.
> The only workaround is to not use entities at all, which is impossible in 
> some situations and inconvenient in most situations. If the client is 
> required to transform entities before handing it to Solr, it might as well be 
> required to also strip tags, and then the HTML stripper would not be needed 
> at all.
> Today, we have a better solution that can be used: offset correction. We can 
> then avoid inserting extra whitespace, but still get correct offsets. The 
> attached patch implements just that.
