<p>Following (Backbone) attributes as standard:</p>
<ul>
<li>id: a unique identifer for this field- usually this should match the key in the documents hash</li>
<li>label: (optional: defaults to id) the visible label used for this field</li>
<li>type: (optional: defaults to string) the type of the data in this field. Should be a string as per type names defined by ElasticSearch - see Types list on <a href="http://www.elasticsearch.org/guide/reference/mapping/">http://www.elasticsearch.org/guide/reference/mapping/</a></li>
<li>format: (optional) used to indicate how the data should be formatted. For example:
<ul><li>type=date, format=yyyy-mm-dd</li>
<li>type=float, format=percentage</li>
<li>type=string, format=markdown (render as markdown if Showdown available)</li></ul></li>
<li>is_derived: (default: false) attribute indicating this field has no backend data but is just derived from other fields (see below).</li>
</ul>
<p>Following additional instance properties:</p>
<p>@property {Function} renderer: a function to render the data for this field.
Signature: function(value, field, doc) where value is the value of this
cell, field is corresponding field object and document is the document
object. Note that implementing functions can ignore arguments (e.g.
function(value) would be a valid formatter function).</p>
<p>@property {Function} deriver: a function to derive/compute the value of data
in this field as a function of this field's value (if any) and the current
document, its signature and behaviour is the same as for renderer. Use of
this function allows you to define an entirely new value for data in this
field. This provides support for a) 'derived/computed' fields: i.e. fields
whose data are functions of the data in other fields b) transforming the
value of this field prior to rendering.</p>
<h4>Default renderers</h4>
<ul>
<li>string
<ul><li>no format provided: pass through but convert http:// to hyperlinks </li>
<li>format = plain: do no processing on the source text</li>
<li>format = markdown: process as markdown (if Showdown library available)</li></ul></li>
<li>float
<ul><li>format = percentage: format as a percentage</li></ul></li>

<p>Query instances encapsulate a query to the backend (see <a
href="backend/base.html">query method on backend</a>). Useful both
for creating queries and for storing and manipulating query state -
e.g. from a query editor).</p>
<p><strong>Query Structure and format</strong></p>
<p>Query structure should follow that of <a href="http://www.elasticsearch.org/guide/reference/api/search/">ElasticSearch query
language</a>.</p>
<p><strong>NB: It is up to specific backends how to implement and support this query
structure. Different backends might choose to implement things differently
or not support certain features. Please check your backend for details.</strong></p>
<p>Query object has the following key attributes:</p>
<ul>
<li>size (=limit): number of results to return</li>
<li>from (=offset): offset into result set - http://www.elasticsearch.org/guide/reference/api/search/from-size.html</li>
<li>sort: sort order - <a href="http://www.elasticsearch.org/guide/reference/api/search/sort.html">http://www.elasticsearch.org/guide/reference/api/search/sort.html</a></li>
<li>query: Query in ES Query DSL <a href="http://www.elasticsearch.org/guide/reference/api/search/query.html">http://www.elasticsearch.org/guide/reference/api/search/query.html</a></li>
<li>filter: See filters and <a href="http://www.elasticsearch.org/guide/reference/query-dsl/filtered-query.html">Filtered Query</a></li>
<li>fields: set of fields to return - http://www.elasticsearch.org/guide/reference/api/search/fields.html</li>
<li>facets: specification of facets - see http://www.elasticsearch.org/guide/reference/api/search/facets/</li>
</ul>
<p>Additions:</p>
<ul>
<li><p>q: either straight text or a hash will map directly onto a <a href="http://www.elasticsearch.org/guide/reference/query-dsl/query-string-query.html">query_string
query</a>
in backend</p>
<ul><li>Of course this can be re-interpreted by different backends. E.g. some
may just pass this straight through e.g. for an SQL backend this could be
the full SQL query</li></ul></li>
<li><p>filters: dict of ElasticSearch filters. These will be and-ed together for
execution.</p></li>

<p>Object to store Facet information, that is summary information (e.g. values
and counts) about a field obtained by some faceting method on the
backend.</p>
<p>Structure of a facet follows that of Facet results in ElasticSearch, see:
<a href="http://www.elasticsearch.org/guide/reference/api/search/facets/">http://www.elasticsearch.org/guide/reference/api/search/facets/</a></p>

addition compared to ElasticSearch: the "id" field which corresponds to the
key used to specify this facet in the facet query):</p>
<pre>

// type of this facet (terms, range, histogram etc)
"_type" : "terms",
// total number of tokens in the facet
"total": 5,
// @property {number} number of documents which have no value for the field
"missing" : 0,
// number of facet values not included in the returned facets
"other": 0,
// term object ({term: , count: ...})
"terms" : [ {
"term" : "foo",
"count" : 2
