NAME

6       Search::Elasticsearch::Transport - Provides interface between the
7       client class and the Elasticsearch cluster
8

VERSION

10       version 7.30
11

DESCRIPTION

13       The Transport class manages the request cycle. It receives parsed
14       requests from the (user-facing) client class, and tries to execute the
15       request on a node in the cluster, retrying a request if necessary.
16
17       This class does Search::Elasticsearch::Role::Transport and
18       Search::Elasticsearch::Role::Is_Sync.
19

CONFIGURATION

21   "send_get_body_as"
22           $e = Search::Elasticsearch->new(
23               send_get_body_as => 'POST'
24           );
25
26       Certain endpoints like "search()" in
27       Search::Elasticsearch::Client::6_0::Direct default to using a "GET"
28       method, even when they include a request body.  Some proxy servers do
29       not support "GET" requests with a body.  To work around this, the
30       "send_get_body_as"  parameter accepts the following:
31
32       •   "GET"
33
34           The default.  Request bodies are sent as "GET" requests.
35
36       •   "POST"
37
38           The method is changed to "POST" when a body is present.
39
40       •   "source"
41
42           The body is encoded as JSON and added to the query string as the
43           "source" parameter.  This has the advantage of still being a "GET"
44           request (for those filtering on request method) but has the
45           disadvantage of being restricted in size.  The limit depends on the
46           proxies between the client and Elasticsearch, but usually is around
47           4kB.

METHODS

50   "perform_request()"
51       Raw requests can be executed using the transport class as follows:
52
53           $result = $e->transport->perform_request(
54               method => 'POST',
55               path   => '/_search',
56               qs     => { from => 0, size => 10 },
57               body   => {
58                   query => {
59                       match => {
60                           title => "Elasticsearch clients"
61                       }
62                   }
63               }
64           );
65
66       Other than the "method", "path", "qs" and "body" parameters, which
67       should be self-explanatory, it also accepts:
68
69       "ignore"
70           The HTTP error codes which should be ignored instead of throwing an
71           error, eg "404 NOT FOUND":
72
73               $result = $e->transport->perform_request(
74                   method => 'GET',
75                   path   => '/index/type/id'
76                   ignore => [404],
77               );
78
79       "serialize"
80           Whether the "body" should be serialized in the standard way (as
81           plain JSON) or using the special bulk format:  "std" or "bulk".
