Subject [jira] Commented: (LUCENE-2003) Highlighter has problems when you use StandardAnalyzer with LUCENE_29 or simplier StopFilter with stopWordsPosIncr mode switched on
Date Thu, 22 Oct 2009 20:22:59 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12768863#action_12768863

Yonik Seeley commented on LUCENE-2003:
--------------------------------------

bq. You only need to add to the slop the largest inc, because the SpanQuery slop is the dist
allowed between each span.

Learn something new every day :-)

Is this javadoc incorrect, or simply ambiguous, or am I reading it wrong:
{code}
  /** Construct a SpanNearQuery.  Matches spans matching a span from each
   * clause, with up to <code>slop</code> total unmatched positions between
   * them.  * When <code>inOrder</code> is true, the spans from each clause
   * must be * ordered as in <code>clauses</code>. */
  public SpanNearQuery(SpanQuery[] clauses, int slop, boolean inOrder) {
    this(clauses, slop, inOrder, true);     
  }
{code}

The "total" would almost seem to tip the ambiguity toward meaning that it's the total slop
between all clauses.

> This is a followup on LUCENE-1987:
> If you set in HighligterTest the constant static final Version TEST_VERSION = Version.LUCENE_24
to LUCENE_29 or LUCENE_CURRENT, the test testSimpleQueryScorerPhraseHighlighting fails. Please
note, that currently (before LUCENE-2002 is fixed), you must also set the QueryParser to respect
posIncr.
