Hello,

Is it possible to boost a document's score based on something like
fq=site(com.google*).  In other words, I want to boost the score of
documents who's "site" field starts with "com.google".

I'm using the MoreLikeThisHandler.

Thanks for the help,
-- Christopher

Ok, I think I need to do this with BoostQParserPlugin and nested
queries, but I can't quite figure it out.

So this works...
q={!boost b=log(popularity)}(title:barack OR title:obama)

But instead of boosting by popularity, I want to boost by site:
q={!boost b=query({ !query q='site:*.yahoo.com' })}(title:barack OR title:obama)

This is the exception I get...
org.apache.lucene.queryParser.ParseException: Expected identifier at
pos 18 str='{!boost b=query({ !query q='site:*.yahoo.com'
})}(title:barack OR title:obama)'

But that doesn't work.  Any tips?  Thanks.

If I remove the space before !query, this is the error:
Cannot parse ')}': Encountered " ")" ") "" at line 1, column 0.

Perhaps someone knows how parentheses and curlies combine here?

Also: *.yahoo.com will not work. Wildcards do not work at the
beginning of a word. To make this search work, you should reverse the
order of the site name parts: 'com.yahoo.wahoo'.

you can't actually nest parsers like this ... but you can use the "$foo"
sintax to seperate them out into alternate params...

/solr/select/?yourChoice={!query}name:solr&q={!boost+b=$yourChoice}(cat:software+OR+cat:camera)
