>                 URL: https://issues.apache.org/jira/browse/LUCENE-495
>             Project: Lucene - Java
>          Issue Type: Improvement
>          Components: Search
>    Affects Versions: 1.9

> I encountered a problem with the Highlighter, where it was not recognizing MultiPhraseQuery.
> To fix this, I developed the following two patches:
> =====================================================
> 1. Addition to org.apache.lucene.search.MultiPhraseQuery:
> Add the following method:
> /** Returns the set of terms in this phrase. */
> public Term[] getTerms() {
>   ArrayList allTerms = new ArrayList();
>   Iterator iterator = termArrays.iterator();
>   while (iterator.hasNext()) {
>     Term[] terms = (Term[])iterator.next();
>     for (int i = 0, n = terms.length; i < n; ++i) {
>       allTerms.add(terms[i]);
>     }
>   }
>   return (Term[])allTerms.toArray(new Term[0]);
> }
> =====================================================
> 2. Patch to org.apache.lucene.search.highlight.QueryTermExtractor:
> a) Add the following import:
> import org.apache.lucene.search.MultiPhraseQuery;
> b) Add the following code to the end of the getTerms(...) method:
>       else  if(query instanceof MultiPhraseQuery)
>               getTermsFromMultiPhraseQuery((MultiPhraseQuery) query, terms, fieldName);
>   }
> c) Add the following method:
>  private static final void getTermsFromMultiPhraseQuery(MultiPhraseQuery query, HashSet
terms, String fieldName)
>  {
>    Term[] queryTerms = query.getTerms();
>    int i;
>    for (i = 0; i < queryTerms.length; i++)
>    {
>        if((fieldName==null)||(queryTerms[i].field()==fieldName))
>        {
>            terms.add(new WeightedTerm(query.getBoost(),queryTerms[i].text()));
>        }
>    }
>  }
> =====================================================
> Can the team update the repository?
> Thanks
