java.lang.Object
org.apache.lucene.queryparser.flexible.core.processors.QueryNodeProcessorImpl
org.apache.lucene.queryparser.flexible.standard.processors.TermRangeQueryNodeProcessor
- All Implemented Interfaces:
QueryNodeProcessor
This processors process
If a
If a
TermRangeQueryNode
s. It reads the lower and upper bounds value
from the TermRangeQueryNode
object and try to parse their values using a DateFormat
. If the values cannot be parsed to a date value, it will only create the TermRangeQueryNode
using the non-parsed values. If a
StandardQueryConfigHandler.ConfigurationKeys.LOCALE
is defined in the QueryConfigHandler
it will be
used to parse the date, otherwise Locale.getDefault()
will be used. If a
StandardQueryConfigHandler.ConfigurationKeys.DATE_RESOLUTION
is defined and the DateTools.Resolution
is not
null
it will also be used to parse the date value.-
