To search documents of which size is from 10 bytes to 100 bytes, the query is below.
content_length:[10 TO 100]
Date range search is also supported. The syntax is “last_modified:[fromdate TO todate]. The date format supports IsO 8601 or Date Math syntax.
| IsO8601 | YYYY-MM-DDThh:mm:ss.sssZ(ex. 2012-12-02T10:45:23.5Z) |
| Date Math | now, y(Year), M(Month), d(Day), h(hour), m(minute) |
For example, if you look for documents updated from 30 days prior to now(2/21/2012), it’s as below.
last_modified:[now/d-30d TO now]
or
last_modified:[2012-11-23T00:00:00Z TO 2012-12-21T20:00:00Z]
