I have inherited a working SOLR installation, that has not been upgraded since solr 4.0. My task is to bring it forward (at least 6.x, maybe 7.x). I am brand new to SOLR.
Here is my question. In schema.xml, there is this field: <field name="unixdate" type="float" indexed="true" stored="true" /> Question: why is this declared as a float datatype? I'm just looking for an explanation of what is there – any changes come later, after I understand things better. I understand about milliseconds from the epoch. I would expect that the author would have used an integer or a long integer to hold such a millisecond count, or a DateField or TrieDateField. I wonder if there is some Solr magic at work.
