---------------------------------------
Hi,
{code:java}
if (q instanceof MultiTermQuery) {
((MultiTermQuery)q).setRewriteMethod
(MultiTermQuery.CONSTANT_SCORE_BOOLEAN_QUERY_REWRITE);
}
{code}
This changes the original query, so we should clone the query before (this is
what the standard highlighter does when it rewrites queries) - but: maybe
cloning was done before in other highlighter code. This one just looks wrong to
me. Also for large indexes with many terms, this may easily throw
TooManyClausesException, so we should catch this exception somehow and disable
highlighting in that case.
About the payloads encoding: I would not limit the offsets and positions and
use the full 32bit ints, but instead encode them as vInt. The facetting package
already has a method for this (it does similar thins, namely encoding ints into
payloads), maybe we move those byte[] vInt encoders to core utils.

> Spinn off from LUCENE-2878. Since we have positions on a large number of
> queries already in the branch is worth looking at highlighting as a real
> consumer of the API. A prototype is already committed.
