            Description

            I encountered an exception using the keywords below:
            {yyy zzz}

            at org.terrier.matching.PostingListManager.mergeStatistics(PostingListManager.java:230)
            at org.terrier.matching.PostingListManager.addSingleTermAlternatives(PostingListManager.java:282)
            at org.terrier.matching.PostingListManager.<init>(PostingListManager.java:162)
            at org.terrier.matching.taat.Full.match(Full.java:73)
            at org.terrier.querying.Manager.runMatching(Manager.java:676)

            The query: zzz yyy
            returns 0 results. So I think it has something to do with empty-resulting keywords. Also the same error is encountered when using the query:

            {work zzz} {gospel yyy}

            Even if there are results for the query:
            work gospel

            However, the exception does not happen for the query below:
            {work zzz} {message yyy}

            where work and message appears in some documents.

            I can't make a clear conclusion with this.

                  Not going to close this until there is a junit test for PostingListManager.
