[jira] [Updated] (LUCENE-3353) ParametricRangeQueryNodeProcessor
uses incorrect logic at the lower bound
[ https://issues.apache.org/jira/browse/LUCENE-3353?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Comment: was deleted
(was: This seems to be related to LUCENE-1768 and LUCENE-2979, as we need to change the config API, so the timezone would only be another param. Maybe that can be done with the work on those two issues.)
> ParametricRangeQueryNodeProcessor uses incorrect logic at the lower bound
> -------------------------------------------------------------------------
>
> Key: LUCENE-3353
> URL: https://issues.apache.org/jira/browse/LUCENE-3353
> Project: Lucene - Java
> Issue Type: Bug
> Components: modules/queryparser
> Affects Versions: 3.3
> Reporter: Trejkaz
>
> ParametricRangeQueryNodeProcessor currently works as follows:
> # If the operator was LE or GE, set inclusive = true.
> # Set up a calendar
> # If inclusive, set the second time to 23:59:59:999
> # Convert that to a string using the DateResolution.
> The problem is, this breaks for *exclusive* queries. For instance, if the user types in {20100110 TO 20100120} they would expect to get the 10th to the 20th exclusive, i.e. the 11th to the 19th. But in reality, the 10th will be *inclusive*.
> To get an actually-exclusive range for the lower bound, the time should be set to 23:59:59:999, much the same as what is done for the inclusive upper bound.
> I suspect the original query parser has the same issue, though possibly in different words.
