Good afternoon!

I was in the IRC room earlier this morning with a problem, and I'm still having 
difficulty with it.  I'm trying to do a site search upsell so that sponsored 
results can be highlighted and boosted to the top of the results. I need to 
have my default operator set to AND, because if it is set to OR I get rather 
unpredictable results.  For example, out of an index of 300k items, a search 
for "old 97's" yields about 116k because they have the words "old" or "97" in 
them.  With the default operator set to AND, I get 54 results, which would be 
the expected behaviour for the user who wants to find articles and events about 
that band.

Unfortunately, I can't boost certain queries with the default operator set to 
AND, because it adds those terms as a required clause to the search.  I need 
the boosted terms to be an optional clause. I'm trying to do what the docs talk 
about here: 
http://wiki.apache.org/solr/SolrRelevancyCookbook#Boosting_Ranking_Terms

So, my example search is "+(old 97's) id:events.event.88468^100" - which should 
search for the old 97's and optionally boost that individual event if it is 
part of the search results. When I run that search with the default operator 
set to AND, it is parsed into '+(+text:old +PhraseQuery(text:"97 s")) 
+id:events.event.88468^100.0' - making the particular event a required 
component of the search and returning only that 1 result.

When I alter my search to "+(old 97's) || id:events.event.88468^100", it parses 
that to "(+text:old +text:"97 s") id:events.event.88468^100.0", which at first 
appeared to do what I wanted.  With just "old 97's", I get 54 results.  With  
"+(old 97's) || id:events.event.88468^100", I get 54 results with that 
particular event on top.  However, if I try to boost another term, such as 
"+(old 97's) || granada^100" - I get over 300 results because it adds in all of 
the matches for the word "granada".  This is not what I want.  Instead of AND 
or OR, I want AND MAYBE.

This is supported by the Xapian backend that I'm switching from, so I'm really 
hoping there's a way to do this in Solr.  Thank you very much for any help you 
can provide!
