QueryParser, double quotes and wilcard inside the double quotes
Hi all,
Imagine you have the following books which are indexed using Lucene
book1 -> title: "foo bar test"
book2 -> title: "foo barrr test"
book3 -> title: "foo bar bar"
I want to find book1 and book2 using the following query "foo * test". But
if I pass this string to the QueryParser, the QueryParser seems to be
searching for a literal '*' character.
Any idea's how to fix this?
Thanks!
Jochen

A hacky trick I used was put a stop weird instead of the asterisk. If you
search for "foo a test" and use an analyzer that includes a stop filter
(like StandardAnalyzer does), it will match docs 1 and 2.

You can use the QueryParser proximity feature e.g. "foo test"~n where
n is the max distance you want them to be apart. Or look at the
SpanQuery stuff e.g. SpanNearQuery.
