FuzzyCondition.java 文件源码

/**
 * Returns a new {@link FuzzyCondition}.
 *
 * @param boost          The boost for this query clause. Documents matching this clause will (in addition to the
 *                       normal weightings) have their score multiplied by {@code boost}. If {@code null}, then
 *                       {@link #DEFAULT_BOOST} is used as default.
 * @param field          The field name.
 * @param value          The field fuzzy value.
 * @param maxEdits       Must be >= 0 and <= {@link LevenshteinAutomata#MAXIMUM_SUPPORTED_DISTANCE}.
 * @param prefixLength   Length of common (non-fuzzy) prefix
 * @param maxExpansions  The maximum number of terms to match. If this number is greater than {@link
 *                       BooleanQuery#getMaxClauseCount} when the query is rewritten, then the maxClauseCount will
 *                       be used instead.
 * @param transpositions True if transpositions should be treated as a primitive edit operation. If this is false,
 *                       comparisons will implement the classic Levenshtein algorithm.
