    Factory for AnalyzingSuggester
    WARNING: This API is experimental and might change in incompatible ways in the next release.
    • Field Detail


        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).
        See Also:
        Constant Field Values

        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).
        See Also:
        Constant Field Values

        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.
        See Also:
        Constant Field Values

        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.
        See Also:
        Constant Field Values

        public static final String QUERY_ANALYZER
        The analyzer used at "query-time" and "build-time" to analyze suggestions.
        See Also:
        Constant Field Values

        public static final String PRESERVE_POSITION_INCREMENTS
        Whether position holes should appear in the automaton.
