> TrieRangeQuery/Filter is missing one thing: Ranges that have exclusive bounds. For TrieRangeQuery this may not be important for ranges on long or Date (==long) values (because [1..5] is the same like ]0..6[ or ]0..5]). This is not so simple for doubles because you must add/substract 1 from the trie encoded unsigned long.
> To be conform with the other range queries, I will submit a patch that has two additional boolean parameters in the ctors to support inclusive/exclusive ranges for both ends. Internally it will be implemented using TrieUtils.incrementTrieCoded/decrementTrieCoded() but makes life simplier for double ranges (a simple exclusive replacement for the floating point range [0.0..1.0] is not possible without having the underlying unsigned long).
> As Lucene 2.9 was not yet released, I will change the ctors and not preserve the old ones.
