The analyzer is generating holes for the stop words - the position of the
subsequent term is incremented an extra time for each stop word so that
their positions are maintained.

Subject: Why PhraseQuery translate stopwords to "?"
Hi,
My application uses an analyzer with a StopWordFilter. PhraseQuery
translates queries with stopwords by replacing stopwords to "?" characters.
For example, "Java and Lucene" is replaced by "Java ? Lucene" and "to
contribute" is replaced by "? contribute" . Sequence of terms are indexed
without stopwords. Query Searching works when the stopword starts the
phrase but no results when the "?" is not at the beginning.
Searching for phrases without stopwords works well.
Any explanation/FAQ/user-list-message that explains why PhraseQuery
translate stopwords to "?" would be appreciated.
Thank you in advance
Jean-Claude Dauphin
