New support for "Date Math" when adding/quering date fields
-----------------------------------------------------------
Key: SOLR-71
URL: http://issues.apache.org/jira/browse/SOLR-71
Project: Solr
Issue Type: New Feature
Components: search, update
Reporter: Hoss Man
Assigned To: Hoss Man
New utility class and changes to DateField to support syntax like the
following...
startDate:[* TO NOW]
startDate:[* TO NOW/DAY+1DAY]
expirationDate:[NOW/DAY TO *]
reviewDate:[NOW/DAY-1YEAR TO NOW/DAY]
validDate:[NOW/MONTH TO NOW/MONTH+1MONTH-1MILLISECOND]
...where + and - mean what you think, and "/UNIT" rounds down to the nearest
UNIT. The motivation for this being that date range queries like these are
usefull for filters, but being date sensitve can't currently be "baked in" to a
config as default params.
a nice side effect of the implimentation, is that "timestamp" fields can be
done with a document is added by using...
<field name="myTimestampField">NOW</field>
...and Solr will compute the value when adding the document ... if we add
default values to the schema.xml even that won't be neccessary.
Comments?
(I'd be particularly gratefull if smarter people then I would sanity check my
use of ThreadLocal for managing the DateFormat in DateField ... i've never used
ThreadLocal before. Any general comments on the syntax would also be
appreciated: This left-to-right syntax seemed more intuative to write (and
easier to parse) then some of the other syntaxes I'd considered)
