After successfully implementing the code snippet below to retrieve blog posts based on a query, I encountered an issue when attempting to fetch documents that match specific categories.
$params = [
'index' => 'blog',
'type' => 'post',
'body' => [
'query' => [
'multi_match' => [
'query' => $request->get('query'),
'fields' => ['title', 'description']
]
]
]
];
$response = \Elasticsearch::search($params); // functioning correctly
I attempted to modify the code above by including a variable $categories in order to retrieve documents matching any of the specified category values selected from checkboxes.
The $categories variable contains values received from checkboxes.
Despite my efforts, the amended code provided below returned empty results:
// $categories = $request->get('categories');
$categories = ["News", "Technology"];
$params = [
'index' => 'blog',
'type' => 'post',
'body' => [
"query"=> [
"filtered"=> [
"query"=> [
"match_all"=> []
],
"query"=>[
"terms"=> [
"category"=> $categories
]
]
]
]
]
];
$response = \Elasticsearch::search($params); // zero hits returned
If you have any suggestions on how I can adjust the code to retrieve documents based on one or more categories instead of keywords, it would be greatly appreciated.
