I am new to Elasticsearch and I am using REST API for PHP to play around with data returned. I am using following code to retrieve data.
$params = [
'index' => 'my_search',
'type' => 'mytype',
'from' => 0,
'size' => 10,
'body' => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ 'validated' => true ] ],
[ 'match' => [ 'image' => true ] ]
]
]
],
'sort' => [
'created_at' => [ 'order' => 'asc']
]
]
];
Above code returns data perfectly matching "validated=>true" and "image=>true".
Further I want to add open text search like we use /_search/?q=Apple macbook. I have tried to use match, multi_match, query_string options, but couldn't get success.
So, I want to retrieve results from ES that have "validated=>true", "image=>true" and matches with text "Apple macbook".
Thanks in advance.
You can try with query_string or simple_query_string
$params = [
'index' => 'my_search',
'type' => 'mytype',
'from' => 0,
'size' => 10,
'body' => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ 'validated' => true ] ],
[ 'match' => [ 'image' => true ] ],
[ 'query_string' => [ 'query' => 'Apple macbook' ] ]
]
]
],
'sort' => [
'created_at' => [ 'order' => 'asc']
]
]
];
$params = [
'index' => 'my_search',
'type' => 'mytype',
'from' => 0,
'size' => 10,
'body' => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ 'validated' => true ] ],
[ 'match' => [ 'image' => true ] ],
[ 'simple_query_string' => [ 'query' => 'Apple macbook' ] ]
]
]
],
'sort' => [
'created_at' => [ 'order' => 'asc']
]
]
];
you can also do this by
enabling all_field mapping for your index, you can do that by following the below URL
https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-all-field.html
and then use the below ES query:
$params = [
'index' => 'my_search',
'type' => 'mytype',
'from' => 0,
'size' => 10,
'body' => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ '_all' => 'Apple macbook' ] ],
[ 'match' => [ 'validated' => true ] ],
[ 'match' => [ 'image' => true ] ]
]
]
],
'sort' => [
'created_at' => [ 'order' => 'asc']
]
]
];

I made my index with analyzer like in documentation (there).
This is my index create:
$params = [
'index' => 'mytestindex',
'body' => [
'settings' => [
'analysis' => [
'index_analyzer' => [
'my_index_analyzer' => [
'type' => 'custom',
'tokenizer' => 'standard',
'filter' => [
'lowercase',
'mynGram2'
],
],
],
'search_analyzer' => [
'my_search_analyzer' => [
'type' => 'custom',
'tokenizer' => 'standard',
'filter' => [
'standard',
'lowercase',
'mynGram2'
],
],
],
'filter' => [
'mynGram2' => [
'type' => 'nGram',
'min_gram' => 2,
'max_gram' => 20,
],
],
],
'max_ngram_diff' => 50,
],
],
];
$x = $this->obj->indices()->create($params);
Then i try use my analyzer:
$params = [
'index' => 'mytestindex',
'body' => [
'analyzer' => 'my_search_analyzer',
'text' => 'текст проверить чтобы'
],
];
$x = $this->obj->indices()->analyze($params);
But I get this message:
'{"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[PEREGOVOR2][127.0.0.1:9300][indices:admin/analyze[s]]"}],"type":"illegal_argument_exception","reason":"failed
to find analyzer [my_search_analyzer]"},"status":400}'
So... what am I doing wrong? Why can't I use my analyzer and get answer 'failed to find analyze'?
You're not building your analyzer correctly. You only need one analyzer section in your settings:
$params = [
'index' => 'mytestindex',
'body' => [
'settings' => [
'analysis' => [
'analyzer' => [ <--- change this
'my_index_analyzer' => [
'type' => 'custom',
"tokenizer" => "standard",
'filter' => [
"lowercase",
"mynGram2"
],
],
'my_search_analyzer' => [
"type" => "custom",
"tokenizer" => "standard",
'filter' => [
"standard",
"lowercase",
"mynGram2"
],
],
],
'filter' => [
'mynGram2' => [
"type" => "nGram",
"min_gram" => 2,
"max_gram" => 20,
],
],
],
"max_ngram_diff" => "50",
],
],
];
$x = $this->obj->indices()->create($params);
I'm using elasticsearch php and trying to optimize my query contraction in one place. Typical Elasticsearch query like:
$params = [
'index' => 'my_index',
'type' => 'my_type',
'body' => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ 'testField' => 'abc' ] ],
[ 'match' => [ 'testField2' => 'xyz' ] ],
]
]
]
]
];
So the question is, does it possible to put conditional query in $params before 'match' string maybe like:
<?php if (isset($_GET['query'])) [ 'match' => [ 'testField' => 'abc' ] ]; ?>
Thank you in any advice
You can use this:
<?php
$must = [[ 'match' => [ 'testField2' => 'xyz' ] ] ];
if (isset($_GET['query']))
$must[] = [ 'match' => [ 'testField' => 'abc' ] ];
$params = [
'index' => 'my_index',
'type' => 'my_type',
'body' => [
'query' => [
'bool' => [
'must' => $must
]
]
]
];
or this;
<?php
$params = [
'index' => 'my_index',
'type' => 'my_type',
'body' => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ 'testField2' => 'xyz' ] ],
],
]
]
]
];
if (isset($_GET['query']))
$params['body']['query']['bool']['must'][] = [ 'match' => [ 'testField' => 'abc' ] ];
I am trying to add multiple criterion to ElasticSearch PHP in must clause, but it is giving me a 500 Error.
My params are:
$params = ['index' => 'smartjn',
'type' => 'feed_details',
'size' => 10,
'body' => [
'sort' => [
'sorter' => [
'order' => 'desc',
'mode' => 'max'
]
],
'query' => ['bool' => [
'must' => [
['match' => ['approvalStatus' => 'approved']],
[ '_id' => [
'$lt' => new MongoDB\BSON\ObjectId($documentid)
]
]
],
'must_not' => ['term' => ['muteFeedUserIds' => $userID]],
'must_not' => ['term' => ['muteUserIds' => $userID]]
]
]
]
];
Please note that this works if I remove the second criteria in must clause i.e.
$params = ['index' => 'smartjn',
'type' => 'feed_details',
'size' => 10,
'body' => [
'sort' => [
'sorter' => [
'order' => 'desc',
'mode' => 'max'
]
],
'query' => ['bool' => [
'must' => [
['match' => ['approvalStatus' => 'approved']]
],
'must_not' => ['term' => ['muteFeedUserIds' => $userID]],
'must_not' => ['term' => ['muteUserIds' => $userID]]
]
]
]
];
Any idea what am I missing?
Thanks
check this out.
'query' => ['bool' => [
'must' => [
['match' => ['approvalStatus' => 'approved']],
[ 'ids' => [
'values' => [new MongoDB\BSON\ObjectId($documentid)]
]
]
],
'must_not' => ['term' => ['muteFeedUserIds' => $userID]],
'must_not' => ['term' => ['muteUserIds' => $userID]]
]
If that doesnt work i am giving you the raw as i am not good with elasticphp
{
"query": {
"bool": {
"must": [
{
"ids": {
"type": "type_of_index"
"values": ["AVbqtjXfoKQ0pubF_-NA"]
}
}
]
}
}
}
type is optional
Just add this ids part under must area.
I am Using Elasticsearch 2.3 along with the official php driver. The updateByQuery is giving me troubles to use in php. A little help on how to use it will be appreciated.
$client = \Elasticsearch\ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
# Request
$updateRequest = [
'index' => 'gorocket',
'type' => 'logs',
'body' => [
'query' => [
'filtered' => [
'filter' => [
'bool' => [
'must' =>
[
[
'match' => [ 'enabled' => 1 ],
],
]
]
]
]
]
]
]
];
# Update
$results = $client->updateByQuery($updateRequest);
Basically i want to update a couple of document fields(name,price) that matches a certain query
Thank you.
So, with the help of how the CURL api works i managed to come up with a way.
First you need to edit your elasticsearch.yml to allow Scripting. Append the following lines at the end.
script.engine.groovy.inline.search: on
script.engine.groovy.inline.aggs: on
script.engine.groovy.inline.update: on
There after you can start doing batch updates using queries as the example bellow.
$client = \Elasticsearch\ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
# Request
$updateRequest = [
'index' => 'testindex',
'type' => 'logs',
'conflicts' => 'proceed',
'body' => [
'query' => [
'filtered' => [
'filter' => [
'bool' => [
'must' =>
[
[
'match' => [ 'enabled' => 1 ],
],
]
]
]
]
],
'script' => [
'inline' => 'ctx._source.enabled = value',
'params' => [
'value' => 0
]
]
]
]
];
# Update
$results = $client->updateByQuery($updateRequest);
That's it. It is not easily and well documented as of now so.
I want to add a small addition to the previous answer
You may not add the following params in elasticsearch.yml
script.engine.groovy.inline.search: on
script.engine.groovy.inline.aggs: on
script.engine.groovy.inline.update: on
And your query will be:
$client = \Elasticsearch\ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
# Request
$updateRequest = [
'index' => 'testindex',
'type' => 'logs',
'conflicts' => 'proceed',
'body' => [
'query' => [
'filtered' => [
'filter' => [
'bool' => [
'must' => [
[
'match' => [ 'enabled' => 1 ],
],
]
]
]
]
],
'script' => [
'lang' => 'painless',
'source' => 'ctx._source.enabled = params.value',
'params' => [
'value' => 0
]
]
]
];
# Update
$results = $client->updateByQuery($updateRequest);
I'm having a little trouble translating some of the queries I use for elasticsearch into PHP readable queries.
For example this simple query works:
$query = $elastic->search([
body' => [
'query' => [
'match' => [
'myfield' => 'mymatchingresult'
]
]
]
]);
But what I'm trying to get to work follow below. There isn't an error, it just doesn't run. I must not be understanding the structure. The same query if placed in something like google extension sense seems to work. (With the php '=>' converted to ':' etc.)
$query = $elastic->search([
'body' => [
'query' => [
'filtered' => [
'query' => [
'query_string' => [
'query' => '*',
'analyze_wildcard' => 'true'
]
],
'filter' => [
'bool' => [
'must' => [
'query' => [
'query_string' => [
'analyze_wildcard' => 'true',
'query' => 'cn:name'
]
],
'range' => [
'#timestamp' => [
'from' => '2012-05-01',
'to' => '2016-05-01'
]
]
]
]
]
]
]
]
]);
Thank you for the help!

As far as I can tell, the constraints in your bool/must filter must be enclosed in square brackets, i.e. bool/must should be a pure array, not an associative array.
Like this:
$query = $elastic->search([
'body' => [
'query' => [
'filtered' => [
'query' => [
'query_string' => [
'query' => '*',
'analyze_wildcard' => 'true'
]
],
'filter' => [
'bool' => [
'must' => [
[
'query' => [
'query_string' => [
'analyze_wildcard' => 'true',
'query' => 'cn:name'
]
]
],
[
'range' => [
'#timestamp' => [
'from' => '2012-05-01',
'to' => '2016-05-01'
]
]
]
]
]
]
]
]
]
]);
