Uwe Schindler commented on LUCENE-1872:
---------------------------------------
This is correct (first part), you can add a field more than once and it really
works (there is a test about that). The results are the same like with a normal
range query (so the trie terms do not interfere between each other).
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).
