That'll teach me to scan a post. The link I sent you
is still relevant, but wildcards are NOT intended to be used to
concatenate terms. You want a phrase query or a span query
for that. i.e. "A C F"~# where # is the "slop", that is, the number
of other terms allowed to appear between your desired terms.
SpanQueries are constructed programmatically, and PhraseQueries
are produced by the parser.
As I understand it though, there's no way to use the queryparser to
construct an *ordered* phrase query with slop (which is what I think
he's after), right? I gather that'd have to be done manually with a
SpanNearQuery. I'd love to hear that the query parser has syntax for
this though...
QueryParser does not create any SpanQuery's, but one can subclass
QueryParser and override getFieldQuery() to put in a SpanQuery instead
of a PhraseQuery.
