    • Field Detail


        public static final String WEIGHT_BUCKETS
        The number of separate buckets for weights (discretization). The more buckets, the more fine-grained term weights (priorities) can be assigned. The speed of lookup will not decrease for prefixes which have highly-weighted completions (because these are filled-in first), but will decrease significantly for low-weighted terms (but these should be infrequent, so it is all right).

        The number of buckets must be within [1, 255] range.

        Constant Field Values

        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).
