hi !

the query below is working but when i use the php official client but i  
still have the exception : _malformed query, expected a START\_OBJECT_

"query": {  
"function\_score": {  
"query": {  
"terms": {  
"categoryName": [  
"toto",  
"tutu"  
],  
"minimum\_match": 1  
}  
},  
"functions": [  
{  
"filter": {  
"terms": {  
"tags": [  
"truc",  
"bidule"  
]  
}  
},  
"boost\_factor": 2  
}  
]  
}  
}

in my script the query is divided  
both $category and $boost are arrays of values

// function\_score --\> init main query  
$functionScoreQuery = array( 'query' =\> array(  
'terms' =\> array(  
'categoryName' =\> $category  
)  
));

// function\_score functions --\> init boost  
$functionScoreFunctions = array( 'functions' =\> array(  
'filter' =\> array(  
'terms' =\> array(  
'tags' =\> $boost  
)  
),  
'boost\_factor' =\> 2  
));

$defaultSubQuery['function\_score'] = $functionScoreQuery;  
if (($boost)) {  
$defaultSubQuery['function\_score'] +=  
$functionScoreFunctions;  
}

a print\_r() of the request show :

Array  
(  
[index] =\> myIndex  
[body] =\> Array  
(  
[query] =\> Array  
(  
[function\_score] =\> Array  
(  
[query] =\> Array  
(  
[terms] =\> Array  
(  
[categoryName] =\> Array  
(  
[0] =\> toto  
[1] =\> tutu  
)

```
                                    )

                            )

                        [functions] => Array
                            (
                                [filter] => Array
                                    (
                                        [terms] => Array
                                            (
                                                [tags] => Array
                                                    (
                                                        [0] => truc
                                                        [1] => bidule
                                                    )

                                            )

                                    )

                                [boost_factor] => 2
                            )

                    )

            )

[from] => 0
[size] => 10

```

)

--\> function\_score: malformed query, expected a START\_OBJECT while parsing  
functions but got a FIELD\_NAME];

I know the _function\_score_ as a special syntax combining arrays and  
objects  
([http://www.elasticsearch.org/guide/en/elasticsearch/client/php-api/current/\_search\_operations.html](http://www.elasticsearch.org/guide/en/elasticsearch/client/php-api/current/_search_operations.html)  
)

but i didn' found the correct syntax using the official php client  
...examples are quite light in this case so any help will be appreciated 🙂

regards,  
chris

i've found my problem...

an intermediate array was missing (under [functions] see below) in the  
query construction with elasticsearch-php :

[function\_score] =\>

Array  
(

```
                    [query] => Array
                        (
                            [terms] => Array
                                (
                                    [category] => Array
                                        (
                                            [0] => toto
                                            [1] => tutu
                                        )

                                )

                        )

                    [functions] => Array
                        (
                            [0] => Array
                                (
                                    [filter] => Array
                                        (
                                            [terms] => Array
                                                (
                                                    [tags] => Array
                                                        (
                                                            [0] => truc
                                                        )

                                                )

                                        )

                                    [boost_factor] => 2
                                )

                        )

                )
