Hi all,
I am trying to figure out how Lucene gets the offset positionsinformation for
Phrase/MultiPhrase queries when it is doing the highlighting with
"hl.useFastVectorHighlighter=true" .
I know that using FVH, Lucene is able to get the term positions of the termSet from the
TermVectorComponent. But for phrase queries how does Lucene get the offset position of
only the "exact phrase" match?
Mattew,
I'm not sure this is the answer you wanted, but look at:
https://builds.apache.org//job/Lucene-trunk/javadoc/contrib-highlighter/org/apache/lucene/search/vectorhighlight/package-summary.html#package_description
FVH constructs QueryPhraseMap from user query and FieldTermStack from
TermFreqVector info in the index.
