Hi all,
Can someone from the experts here explain why Lucene has to get a rewritten
query for the Searcher - so Phrase or Wildcards queries have to rewrite
themselves into a primitive query, that is then passed to Lucene to look for?
I'm probably not familiar too much with the internals of
Itamar,
Query rewrite replaces wildcards with terms available from
the index. Usually that involves replacing a wildcard with a
BooleanQuery that is an effective OR over the available
terms while using a flat coordination factor, i.e. it does not
matter how many of the available terms actually
Other use is for custom Query objects to reboost or expand the user query
from information gathered from the indexreader at search time.
