Class SortableEntry

java.lang.Object

io.fluxcapacitor.common.api.search.SortableEntry

All Implemented Interfaces:

Comparable<SortableEntry>

public class SortableEntry
extends Object
implements Comparable<SortableEntry>

Represents a sortable entry in a Document for use in search operations.

SortableEntry values are primarily used to support efficient sorting and range filtering in the document store (e.g., numeric or timestamp-based queries). Each entry consists of a name (field path) and a pre-normalized, lexicographically sortable value as a String.

Values are formatted using a normalization strategy depending on their type:

• Numbers: Encoded into padded, base-10 fixed-width strings for fast and correct range comparisons
• Timestamps: Formatted using SearchUtils.ISO_FULL
• Other values: Normalized to lowercase using SearchUtils.normalize(String)

Example Use Cases

• Sorting search results by timestamp or numeric score
• Enabling fast BetweenConstraint evaluation
• Filtering or grouping based on normalized values

• BetweenConstraint
