Google Search Appliance: Search Protocol Reference Dynamic Result Clustering Service /cluster Protocol 92

The top-level entries are described in the following table.

The dynamic result clustering service’s default JavaScript client ignores the

element and

does not use the

<doc>

array. The XML response is very basic, and does not use any validations such as

a DTD or XML.

The following DTD defines the XML rules, however the XML output is not validated against these rules:

<?xml version="1.0"?>

<!ELEMENT toplevel (Response, t_fetch, document+)>

<!ELEMENT Response (algorithm, t_cluster, cluster)>

<!ELEMENT cluster (gcluster+)>

<!-- each gcluster element is an alternate query and its location indexes from the

top results -->

<!ELEMENT gcluster (label, doc+)>

<!-- each document element is search result, complete with url, title, and snippet

-->

<!ELEMENT document (url, title, snippet)>

Entry Description

The output from different clustering algorithms. There is only one supported cluster

algorithm, so the value of

must be

Concepts

The

category consists of:

• A series of

and subordinate

pairs.

• The subordinate

is a series of

<label>

statements and the array of

<doc>

elements that have that label.

• The label is a query suggestion. The

<doc>

statements are indexes into the

section that follows.

Each

<label>

provides an alternative query, and each

<doc>

array provides the

document location indices.

A sequence of the URL, title, and snippet for each of up to 100 top search results

from a search query. The search appliance creates the

<doc>

arrays from the

list.
