: Subject: Local Params syntax not protecting Shingles in DisMax from Lucene
: query parser

: I really like the DisMax query parser, but of course its main design is a
: bit at odds with shingles and phrases. But I'd seen folks talk about using

To be clear: nothing about the local params syntax will "protect" shingles
-- in that thread you linked to i wasn't suggesting that using localparams
would make the problem go away, i was pointing out that the
"field" QParser has no meta-characters of any kind (ie: does not treat
whitespace as special) and passes the entire query string to the Analyzer
for the "f" field. I was just using local params as a way to trigger the
field QParser (defType would have been another way)
