Range queries can be applied to fields with datatypes that have natural ordering. For example, integers, logs, and dates have a natural order. There is no ambiguity in deciding whether one value is less, equal to, or greater than the other values. Because of this well-defined datatypes order, a range query can be applied.

We will look at how to apply range queries in the following ways:

• On numeric types
• With score boosting
• On dates

Let's look at the most typical range query on a numeric field.
