If you're searching for terms "giving" and "and", it will only highlight those terms, not the whole sentence.. that's how the highlighter is meant to work: highlight what the user did query. Also there's no built-in concept of sentence. regards, Sanne 2010/1/11 Li Leon : > Just figured out, missed "lucene-memory-2.4.1.jar" external jar inclusion. > > With that jar included, "\"Giving and\"~11" only got "Giving" & "and" > highlighted but not the whole sentence, any ideas? > > Thanks, > > 2010/1/11 Li Leon > >> *Hi all,* >> ** >> *I wanted to use to following code to highlight the whole sentence with >> "\"something\"~n" to be parsed.* >> ** >> *The QueryParser part worked well, but when integrated with Highlighter, >> it ended up with exception. * >> ** >> *Does anyone have any clue as I'm investigating this.* >> ** >> ** >> *Thanks,* >> ** >> >> >> >> Exception in thread "main" java.lang.NoClassDefFoundError: >> org/apache/lucene/index/memory/MemoryIndex >> >>       at >> org.apache.lucene.search.highlight.WeightedSpanTermExtractor.getReaderForField( >> *WeightedSpanTermExtractor.java:361*) >> >>       at >> org.apache.lucene.search.highlight.WeightedSpanTermExtractor.extractWeightedSpanTerms( >> *WeightedSpanTermExtractor.java:282*) >> >>       at >> org.apache.lucene.search.highlight.WeightedSpanTermExtractor.extract(* >> WeightedSpanTermExtractor.java:149*) >> >>       at >> org.apache.lucene.search.highlight.WeightedSpanTermExtractor.getWeightedSpanTerms( >> *WeightedSpanTermExtractor.java:414*) >> >>       at org.apache.lucene.search.highlight.QueryScorer.initExtractor(* >> QueryScorer.java:216*) >> >>       at org.apache.lucene.search.highlight.QueryScorer.init(* >> QueryScorer.java:184*) >> >>       at >> org.apache.lucene.search.highlight.Highlighter.getBestTextFragments(* >> Highlighter.java:226*) >> >>      at org.apache.lucene.search.highlight.Highlighter.getBestFragments(* >> Highlighter.java:184*) >> >>      at org.apache.lucene.search.highlight.Highlighter.getBestFragments(* >> Highlighter.java:488*) >> >>       at Hightlight.main(*Hightlight.java:182*) >> >> >> ** >> *public* *class* Hightlight { >> >>   *private* *static* *final* String *text* = >> >>     "Giving end users some context around hits from their searches is >> friendly and, more important, useful.
