window_match
window_match(str fieldname, unsigned int dt0, unsigned int dt1) allows window matching between dates.
The function returns True if params[fieldname]is between doc[fieldname] - dt0 to doc[fieldname] - dt1
Input
fieldname (str) - the name of the field to match in query docmuent and database document. params[fieldname] and doc[fieldname] must be of type int
dt0 (unsigned int) - the left margin of the window. Must include units (s/m/h/d).
dt1 (unsigned int) - the right margin of the window. Must include units (s/m/h/d).
Output
(Boolean) - True
if doc[fieldname] - dt0 < params[fieldname] < doc[fieldname] - dt1, and False otherwise.
Example:
The window_match condition will return True if
doc[fieldname] - 3d< params[fieldname] < doc[fieldname] - 2d
For example, if params[fieldname]=1698225495, which is equivalent to GMT October 25, 2023 9:18:15 AM, and doc[fieldname]=1698311895, which is equivalent to GMT October 26, 2023 9:18:15 AM, then window_match will return false because params[fieldname] > params[fieldname] - 2d
