How to GET Employee Absences data from HCM Fusion by sending two dates in REST API query parameter

I would like to GET employee last 2 months and future 2 months absences data.

REST API: https://host:port/hcmRestApi/resources/11.13.18.05/absences

https://host:port/hcmRestApi/resources/11.13.18.05/absences?q=startDate between '2018-09-22' and '2018-09-25'
https://host:port/hcmRestApi/resources/11.13.18.05/absences?q=startDate>2018-09-22;startDate<2018-09-25

Tried different options but no luck. Please advise!
