php full text search in elasticsearch - php

Question

I have a json file which I looped through it and index it in elastic. and after that I want to be able to search through my data.
this is my json file :
https://github.com/mhndev/iran-geography/blob/master/tehran_intersection.json
which looks like :
{
"RECORDS":[
{
"first":{
"name":"ابن بابویه",
"slug":"Ibn Babawayh"
},
"second":{
"name":"میرعابدینی",
"slug":"Myrabdyny"
},
"latitude":"35.601605",
"longitude":"51.444208",
"type":"intersection",
"id":1,
"search":"ابن بابویه میرعابدینی,Ibn Babawayh Myrabdyny,ابن بابویه تقاطع میرعابدینی,Ibn Babawayh taghato Myrabdyny",
"name":"ابن بابویه میرعابدینی",
"slug":"Ibn Babawayh Myrabdyny"
},
...
]
}
when my query is : "mir", I expect my result to be records which has "mirabedini", "mirdamad", "samir", and every other word which contains this string.
but I just get words which are exactly "mir"
and this is my php code for search :
$fields = ['search','slug'];
$params = [
'index' => 'digipeyk',
'type' => 'location',
'body' => [
'query' => [
'match' => [
'fields' => $fields,
'query' => $_GET['query']
]
],
'from' => 0,
'size' => 10
]
];
$client = ClientBuilder::create()->build();
$response = $client->search($params);
and also this my php code for indexing documents.
$client = ClientBuilder::create()->build();
$deleteParams = ['index' => 'digipeyk'];
$response = $client->indices()->delete($deleteParams);
$intersections = json_decode(file_get_contents('data/tehran_intersection.json'), true)['RECORDS'];
$i = 1;
foreach($intersections as $intersection){
echo $i."\n";
$params['index'] = 'digipeyk';
$params['id'] = $intersection['id'];
$params['type'] = 'location';
$params['body'] = $intersection;
$response = $client->index($params);
$i++;
}
I'm using php 7 and elasticsearch 2.3

Answer 1

match query doesn't support wildcard query by default, so you have to use wildcard instead of that.
$fields = ['search','slug'];
$params = [
'index' => 'digipeyk',
'type' => 'location',
'body' => [
'query' => [
'wildcard' => [
'query' => '*'.$_GET['query'].'*'
]
],
'from' => 0,
'size' => 10
]
];
$client = ClientBuilder::create()->build();
$response = $client->search($params);
For more information about wildcard in elastic visit following link : https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html

Answer 2

For that:
'query' => $_GET['query']
You will be burn in hell :D
