[jira] Updated: (LUCENE-1530) Support inclusive/exclusive for
TrieRangeQuery/-Filter
[ https://issues.apache.org/jira/browse/LUCENE-1530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Uwe Schindler updated LUCENE-1530:
----------------------------------
Attachment: LUCENE-1530.patch
The patch. If nobody complains and the removal of not yet released constructors without the boolean parameters is ok, I commit.

> 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.
