Reading more closely, I see that there is a workaround: add a space after
any left parenthesis.
So, try this:
q=chairs+AND+(+regularprice:*^5+OR+(+*:*+-regularprice:*)^5)
Here's an example of my own:
http://localhost:8983/solr/select/?q=the+AND+(+price:*^5+OR+(+*:*+-price:*)^0.5)&defType=edismax&debugQuery=true&qf=text

Oh well, it looks like my suggestion is running into "SOLR-3377 - eDismax: A
fielded query wrapped by parens is not recognized".
See:
https://issues.apache.org/jira/browse/SOLR-3377
That issue has a patch, but not yet committed.
That explains why it works in the traditional Solr/Lucene query parser, but
not in edismax.
http://localhost:8983/solr/select/?q=the+AND+(price:*^5+OR+(*:*+-price:*)^0.5)

It may not matter, but the spaces in the query should be uuencoded as "+".
I have the query working with Solr query, but it is giving me no docs for
edismax for some reason. But, it does seem to work if I reverse the order of
the query terms to be:
http://localhost:8983/solr/select/?q=*:*+AND+((*:*+-price:*)^0.5+OR+price:*^5)&defType=edismax&debugQuery=true&qf=text
Let me try a couple more things.

Same effect.

OK it looks like the query change is working but it looks like it boosting
everything even documents that have that field empty....

Still doesnt appear to be working. Here is the full Query string:
defType=edismax&start=0&rows=****24&facet=true&qf=nameSuggest^****10
name^10
codeTXT^2 description^1 brand_search^0
cat_search^10&spellcheck=true&****spellcheck.collate=true&**

AND (regularprice:*^5 OR (*:* -regularprice:*)5)

Sorry, make that:

I forgot that pure negative queries are broken again, so you need the
*:*
in there.
I noticed that you second boost operator was missing as well.

So, if a doc has anything in the field, it gets boosted, and if the
doc
does not have anything in the field, de-boost it. Choose the boost
factors
to suit your desired boosting effect.

Subject: Re: Boosting on field empty or not
OK maybe i need to describe this a little more.
Basically I want documents that have a given field populated to have a
higher score than the documents that dont. So if you search for foo I
want
documents that contain foo, but i want the documents that have field a
populated to have a higher score...
Is there a way to do this?

Is there a way to boost a document based on whether the field is
empty
or
not. I am looking to boost documents that have a specific field
populated.
