【问题描述】:
我正在使用 php 的客户端库进行弹性搜索。我想创建一个索引来索引一个人的id 和他的name,并允许用户以非常灵活的方式搜索名称(不区分大小写、搜索部分名称等)。
这是我到目前为止的代码 sn-p,为方便起见,用 cmets 注释
<?php
require_once(__DIR__ . '/../init.php');
$client = new Elasticsearch\Client();
$params = [
'index' => 'person',
'body' => [
'settings' => [
// Simple setings for now, single shard
'number_of_shards' => 1,
'number_of_replicas' => 0,
'analysis' => [
'filter' => [
'shingle' => [
'type' => 'shingle'
]
],
'analyzer' => [
'my_ngram_analyzer' => [
'tokenizer' => 'my_ngram_tokenizer',
]
],
// Allow searching for partial names with nGram
'tokenizer' => [
'my_ngram_tokenizer' => [
'type' => 'nGram',
'min_gram' => 1,
'max_gram' => 15,
'token_chars' => ['letter', 'digit']
]
]
]
],
'mappings' => [
'_default_' => [
'properties' => [
'person_id' => [
'type' => 'string',
'index' => 'not_analyzed',
],
// The name of the person
'value' => [
'type' => 'string',
'analyzer' => 'my_ngram_analyzer',
'term_vector' => 'yes',
'copy_to' => 'combined'
],
]
],
]
]
];
// Create index `person` with ngram indexing
$client->indices()->create($params);
// Index a single person using this indexing scheme
$params = array();
$params['body'] = array('person_id' => '1234', 'value' => 'Johnny Appleseed');
$params['index'] = 'person';
$params['type'] = 'type';
$params['id'] = 'id';
$ret = $client->index($params);
// Get that document (to prove it's in there)
$getParams = array();
$getParams['index'] = 'person';
$getParams['type'] = 'type';
$getParams['id'] = 'id';
$retDoc = $client->get($getParams);
print_r($retDoc); // success
// Search for that document
$searchParams['index'] = 'person';
$searchParams['type'] = 'type';
$searchParams['body']['query']['match']['value'] = 'J';
$queryResponse = $client->search($searchParams);
print_r($queryResponse); // FAILURE
// blow away index so that we can run the script again immediately
$deleteParams = array();
$deleteParams['index'] = 'person';
$retDelete = $client->indices()->delete($deleteParams);
我有时会使用此搜索功能,但我一直在对脚本大惊小怪,以使不区分大小写的功能按预期工作,并且在此过程中,脚本现在无法找到任何具有 J 的人或j 用作要匹配的查询值。
有什么想法吗?
