This is correct (first part), you can add a field more than once and it really
works (there is a test about that: TestMultiValuedNumericRangeQuery). The
results are the same like with a normal range query (so the trie terms do not
interfere between each other). See SOLR-1322
I think your sentence is a little bit complicated. It would hit all documents
in the range, where at least one of the values of a multi-valued doc is in the
range.
About the second one: Sorting is not different from other numeric multi-value
fields (in contrast to StringIndex where only one value/doc is allowed). The
univerter assigns a value to each document. As it overrides values previously
assigned to the document when iterating over all terms in the field, the last
term would be the one saved in the FieldCache. So you would sort against the
largest value per doc (because the smaller values are overridden by the larger
ones in the field cache).
