Field Summary

Fields

Modifier and Type	Field and Description
static String	EXACT_MATCH_FIRST If true, exact suggestions are returned first, even if they are prefixes of other strings in the automaton (possibly with larger weights).
static String	MAX_EXPANSIONS When building the FST ("index-time"), we add each path through the tokenstream graph as an individual entry.
static String	MAX_SURFACE_FORMS When multiple suggestions collide to the same analyzed form, this is the limit of how many unique surface forms we keep.
static String	PRESERVE_SEP If true, then a separator between tokens is preserved.
static String	QUERY_ANALYZER The analyzer used at "query-time" and "build-time" to analyze suggestions.

Field Detail

EXACT_MATCH_FIRST

public static final String EXACT_MATCH_FIRST

If true, exact suggestions are returned first, even if they are prefixes of other strings in the automaton (possibly with larger weights).

Constant Field Values

PRESERVE_SEP

public static final String PRESERVE_SEP

If true, then a separator between tokens is preserved. This means that suggestions are sensitive to tokenization (e.g. baseball is different from base ball).

Constant Field Values

MAX_SURFACE_FORMS

public static final String MAX_SURFACE_FORMS

When multiple suggestions collide to the same analyzed form, this is the limit of how many unique surface forms we keep.

Constant Field Values

MAX_EXPANSIONS

public static final String MAX_EXPANSIONS

When building the FST ("index-time"), we add each path through the tokenstream graph as an individual entry. This places an upper-bound on how many expansions will be added for a single suggestion.

Constant Field Values

QUERY_ANALYZER

public static final String QUERY_ANALYZER

The analyzer used at "query-time" and "build-time" to analyze suggestions.
