Welcome! Cool use of Solr too.
1. I have a minor remark about the inconsistencies in the
query-parameter definitions... Sometimes multiple fields are given
with comma/space-separated values, sometimes they are given by
repeating the parameter:
sort=field1,field2 desc,field3
but
facet.field=field1&facet.field=field2
This is pretty confusing to first-hand users! :-)
Yeah, it is confusing. But we have to be careful with order. I
don't believe you can rely on the order of same named request
parameters (right?), so sort needs to be a list where order matters.
Whereas with facet.field, order does not matter.
2. two questions about the query syntax:
is
tag:(bass drum)
the same as:
tag:bass OR tag:drum
or the same as:
tag:bass AND tag:drum
or neither?
Using the standard Solr/Lucene query parser, tag:(bass drum) will use
the operator specified in schema.xml, and it defaults to OR.
is "+bass +drum" essentially the same as "bass AND drum" ?
yes, exactly the same.
I'm working on a query/parameter builder in python.
Cool deal. Might be worth collaborating with the pysolr project
here: <http://code.google.com/p/pysolr/> so as to not duplicate efforts.
