                                                        boolean includeTo)

Will create a Query with a query for numeric ranges, that is values that have been indexed using ValueContext.indexNumeric(). It will match the type of numbers supplied to the type of values that are indexed in the index, f.ex. long, int, float and double. If both from and to is null then it will default to int.

Parameters:

key - the property key to query.

from - the low end of the range (inclusive)

to - the high end of the range (inclusive)

includeFrom - whether or not from (the lower bound) is inclusive or not.

includeTo - whether or not to (the higher bound) is inclusive or not.

Returns:

a Query to do numeric range queries with.
