Hi, is there any way in SOLR 5.3 to achieve grouping and do mathematical operations like sum, avg on a certain document property?
Please find below example: <doc> <str name="property_code">HIKS</str> <str name="property_name">Hotel Holiday Inn King's cross</str> <date name="day_of_year>2016-08-21T14:05:00Z</date> <long name="number_of_adults">4</long> <double name="price">40.99</double> </doc> <doc> <str name="property_code">HIKS</str> <str name="property_name">Hotel Holiday Inn King's cross</str> <date name="day_of_year>2016-08-22T14:05:00Z</date> <long name="number_of_adults">4</long> <double name="price">40.99</double> </doc> <doc> <str name="property_code">HIKS</str> <str name="property_name">Hotel Holiday Inn King's cross</str> <date name="day_of_year>2016-08-23T14:05:00Z</date> <long name="number_of_adults">4</long> <double name="price">40.99</double> </doc> We would need to group by the property_code (HIKS) and get the sum of all the prices from the resulting group.
