Heliosearch v0.09 Features:

o Heliosearch v0.09 is based on (and contains all features of)
Lucene/Solr 4.10.2 + most of 4.10.3

o Distributed search support for the new faceted search module / JSON
Facet API: http://heliosearch.org/json-facet-api/

o Automatic conversion of legacy field/range/query facets when
facet.version=2 is passed. This includes support for the deprecated
heliosearch syntax of facet.stat=facet_function and
subfacet.parentfacet.type=facet_param.

o New JSON Request API:
http://heliosearch.org/heliosearch-solr-json-request-api/

Example:
$ curl -XGET http://localhost:8983/solr/query -d '
{
query : "*:*",
filter : [
"author:brandon",
"genre_s:fantasy"
],
offset : 0,
limit : 5,
fields : ["title","author"], // we could also use the string form
"title,author"
sort : "sequence_i desc",

facet : { // the JSON Facet API is nicely integrated as well
avg_price : "avg(price)",
top_authors : {terms : author}
}
}'

This includes "smart JSON merging" including support for a mixed
environment of normal request params and JSON objects / snippets.
