Search in elasticsearch using php curl - php

Question

I have make the application with elasticsearch and everything is running perfectly except the search using the php curl; the error is below
[match] query parsed in simplified form, with direct field name, but included more options than just the field name, possibly use its 'options' form, with 'query' element?]
but the same query is running perfectly in the command-line.
When I do some changes, I found this is occurring by the curl POST.
I am using the following code to run the php curl and tried the GET method too
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 200);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, strtoupper($method));
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));
$response = curl_exec($ch);
curl_close ($ch);
and the query is
{"query":{"filtered":{"query":{"bool":{"should":[{"bool":{"should":[{"match_phrase":{"name":"india"}}],"boost":16}},{"bool":{"should":[{"match_phrase":{"description":"india"}}],"boost":8}},{"bool":{"should":[{"match":{"name":{"query":"india","analyzer":"standard"}}},{"match":{"description":{"query":"india","analyzer":"standard"}}}],"boost":4}},{"match":{"name.ngram":[{"query":"india","analyzer":"standard"}]}},{"match":{"description":[{"query":"india","analyzer":"standard"}]}},{"match":{"name.ngram":[{"query":"india","analyzer":"standard","fuzziness":"auto"}]}},{"match":{"description":[{"query":"india","analyzer":"standard","fuzziness":"auto"}]}}],"boost":2}},"filter":{"and":[{"terms":{"type":["book"]}},{"range":{"price":{"from":"1","to":"100"}}}]}}},"from":0,"size":20,"filter":{"and":[]},"sort":[{"popularity":{"order":"desc","missing":"_last"}}]}

Problem might be in you are using blank filters in your query dsl.
"filter": {
"and":[]
}
Try without blank filters. Also top level filters are renamed in Elasticsearch 1.0 + version.
Update Query DSL:
{
"query": {
"filtered": {
"query": {
"bool": {
"should": [
{
"bool": {
"should": [
{
"match_phrase": {
"name": "india"
}
}
],
"boost": 16
}
},
{
"bool": {
"should": [
{
"match_phrase": {
"description": "india"
}
}
],
"boost": 8
}
},
{
"bool": {
"should": [
{
"match": {
"name": {
"query": "india",
"analyzer": "standard"
}
}
},
{
"match": {
"description": {
"query": "india",
"analyzer": "standard"
}
}
}
],
"boost": 4
}
},
{
"match": {
"name.ngram": [
{
"query": "india",
"analyzer": "standard"
}
]
}
},
{
"match": {
"description": [
{
"query": "india",
"analyzer": "standard"
}
]
}
},
{
"match": {
"name.ngram": [
{
"query": "india",
"analyzer": "standard",
"fuzziness": "auto"
}
]
}
},
{
"match": {
"description": [
{
"query": "india",
"analyzer": "standard",
"fuzziness": "auto"
}
]
}
}
],
"boost": 2
}
},
"filter": {
"and": [
{
"terms": {
"type": [
"book"
]
}
},
{
"range": {
"price": {
"from": "1",
"to": "100"
}
}
}
]
}
}
},
"from": 0,
"size": 20,
"sort": [
{
"popularity": {
"order": "desc",
"missing": "_last"
}
}
]
}

I found the solution; below is the correct json
{"query":{"filtered":{"query":{"bool":{"should":[{"bool":{"should":[{"match_phrase":{"name":"india"}}],"boost":16}},{"bool":{"should":[{"match_phrase":{"description":"india"}}],"boost":8}},{"bool":{"should":[{"match":{"name":{"query":"india","analyzer":"standard"}}},{"match":{"description":{"query":"india","analyzer":"standard"}}}],"boost":4}},{"match":{"name.ngram":{"query":"india","analyzer":"standard"}}},{"match":{"description":{"query":"india","analyzer":"standard"}}},{"match":{"name.ngram":{"query":"india","analyzer":"standard","fuzziness":"auto"}}},{"match":{"description":{"query":"india","analyzer":"standard","fuzziness":"auto"}}}],"boost":2}},"filter":[]}},"from":0,"size":20,"sort":[{"popularity":{"order":"desc","missing":"_last"}}]}
the problem is in the match query phase; I was appending the parameters in match query as nested array.
Now I have removed the nested array and append the options in match query phase as sequential array
Thanks guys for your co-opration
