Hi list,
I'm having difficulties getting the solr highlighter to highlight only the
terms that actually caused the match. Let med explain:
Given a query "john OR (peter AND mary)"
and two documents:
"john is awesome and so is peter"
"peter is awesome and so is mary",
solr will highlight "peter" and "mary" in the second document, which is
expected.
However it will also highlight both 'john' and 'peter' in the first
document, even though peter requires that mary is present also.
Is there any way to improve this?
If I add debugQuery, the explain-block can easily tell me that the first
document matched because of john, giving it a score of 1, whereas the
second matched because of the presence of both peter and mary, giving it a
score of 2.
So somehow, the information is available, but not used by the highlighter.
Below, I have included a real world solr output to explain what I mean.
Thanks,
Bjarke
