-/** The positionIncrement determines the position of this token
- * relative to the previous Token in a {@link TokenStream}, used in phrase
- * searching.
- *
- * <p>The default value is one.
- *
- * <p>Some common uses for this are:<ul>
- *
- * <li>Set it to zero to put multiple terms in the same position.  This is
- * useful if, e.g., a word has multiple stems.  Searches for phrases
- * including either stem will match.  In this case, all but the first stem's
- * increment should be set to zero: the increment of the first instance
- * should be one.  Repeating a token with an increment of zero can also be
- * used to boost the scores of matches on that token.
- *
- * <li>Set it to values greater than one to inhibit exact phrase matches.
- * If, for example, one does not want phrases to match across removed stop
- * words, then one could build a stop word filter that removes stop words and
- * also sets the increment to the number of stop words removed before each
- * non-stop word.  Then exact phrase queries will only match when the terms
- * occur with no intervening stop words.
- *
- * </ul>
