SpanNearQuery can be used to allow an arbitrary number of terms between
sub-phrases of a larger phrase. But, that is between terms, not at the
beginning or end of a phrase.
See:
http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/spans/SpanNearQuery.html You can use SpanMultiTermQueryWrapper to include wild and fuzzy terms in
your span query.
See:
http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/spans/SpanMultiTermQueryWrapper.html You can also use SpanPositionRangeQuery to assure that a phrase match occurs
with a desired position range, such as to assure that the match occurs at
the beginning, near the beginning, or end of a document.

Is * a placeholder for a term or a part of a term?

Subject: using phrase query with wildcard
Hi,
I'm trying to create a phrase query with wildcard, from the forums it seems
that the solution is not trivial.
I'm trying to create the following queries: "this is a phrase*" OR "*This
is a phrase" and Get hits on every possibility where the * resides.
What is the best way to achieve this?
Thanks.
