php - Elasticsearch MapperParsingException [无法解析，文档为空] 在索引期间

Answer 1

Solved . it was an encoding problem. my data was coming from mysql server , i had to set the correct charset option during pdo object initialization.

Answer 2

It is an encoding problem due to special chars, I recomend to escape the text you're trying to index with

$text = html_entity_decode(htmlentities($text, ENT_IGNORE, "UTF-8"));
