Hello everyone, I have a question regarding prefix filtering and symbols_to_index. So I have documents with a field path:

['name' => 'path', 'type' => 'string', 'optional' => true, 'sort' => false],

A path is the ids of its mapping through the category tree separated by a |. So something like 2|13|113. Therefore I added to the document.

'symbols_to_index' => ['|']

To my

filter_by

I'm adding the following statement. However it does not provide me the right results.

path:=10 || path:=10|*

So basically I want to receive any category that is part of the tree which is started by category with id 10. Somehow I just receive like 3 or 4 results instead of all 50 categories. Does the prefix not working with special characters like |? I also tried it with a

.

or

_

. Any help would be much appreciated! Thanks in advance
