Terje Eggestad updated LUCENE-2587: ----------------------------------- Attachment: IMSentenceFragmenter.java My sentence fragmenter > Highlighter picks wrong offset for fragment boundaries > ------------------------------------------------------ > > Key: LUCENE-2587 > URL: https://issues.apache.org/jira/browse/LUCENE-2587 > Project: Lucene - Java > Issue Type: Bug > Components: modules/highlighter > Affects Versions: 3.0.2 > Environment: Java 6 + Lucene 3.0.2 > Reporter: Terje Eggestad > Priority: Trivial > Labels: newdev > Attachments: IMSentenceFragmenter.java > > > I have written a new Fragmenter since we need fragments for hitlines to be > on sentence boundaries and not cross paragraphs. > When using it with org.apache.lucene.search.highlight.Highlighter, I get > hitlines that starts with ". ", "? ", "! "... > Consider the text "A b c d e. F g h i j! K l m n o. " > which become the tokenstream : (A) (b) (c) (d) (e) (F) (g) (h) (i) (j) (K) > (l) (m) (n) (o) > If the fragmenter return isNewFragment() = true on F and K and Highlighter > pick the middle fragment, lets say we search on "g" the hitline becomes: > ". F <B>g</B> h i j" > The reason, it seems, is that the offset to the fragment boundaries found by > taking the endOffset of the last token in a fragment , > not the startOffset of the first. > TJ -- This message is automatically generated by JIRA.
