Fix Version/s: 3.6

Type: Bug Priority: Trivial

Attachments: File DFRBagExpansionTerms.java.patch    

In the class org.terrier.querying.DFRBagExpansionTerms (subclass of org.terrier.querying.ExpansionTerms) the "Conservative QE" won't work because the variable int i (line 170) is not incremented while iterating over the set of original query terms, i.e., the variable SingleTermQuery[] results (line 151) won't be properly filled.

Possible patch attached.
