: I'm getting confused about the method Map<String,String[]> : toMultiMap(NamedList params) in SolrParams class.
toMultiMap probably shouldn't have ever been made public -- it' really only ment to be use by toSolrParams (it's refactored out to make the code easier to read) : When some of your parameter is instanceof String[] it's converted to to : String using the toString() method, which seems : to me to be wrong. It is probably assuming, that the values in NamedList are : all String, but when you look at the method It's not assuming that the NamedList only contains Strings -- it's assuming that since it needs to produce a String[] then every object in the NamedList should be toString()ed to get a String. in your case since the object is already String[] that seems silly -- but you have to keep in mind the whole point is to build a String[] out of *multiple* objects (that have the same key in the NamedList) ... so if your NamedLIst contained two String[]'s with the same key, what would you expect it to do if the behavior was different (union the two arrays?) -Hoss
