yii2.0 elasticsearch模糊查询

like conditions are not supported by elasticsearch.

在QueryBuilder.php中查找到这个函数

private function buildLikeCondition($operator, $operands)
{
throw new NotSupportedException('like conditions are not supported by elasticsearch.');

}
修改此函数为：

private function buildLikeCondition($operator, $operands)
{
if (!isset($operands[0], $operands[1])) {
throw new InvalidParamException("Operator '$operator' requires two operands.");
}
if($operator=="like"){
return [
'regexp' => [
$operands[0]=>".*".$operands[1].".*",
],
];
}else{
throw new NotSupportedException('like conditions are not supported by elasticsearch.');
}
}
解决了like模糊查询，用到了正则匹配语句。暂时解决了项目模糊查询的需要。用正则”regexp“应该还可以用wildcards查询，后者没用过，用过再补上
