Lucene样式查询字符串Elasticsearch PHP

Question

I have searched for days how to query data from Elasticsearch with an array as parameter or with JSON formaat like showing on this page http://www.elasticsearch.org/guide/en/elasticsearch/client/php-api/current/_quickstart.html But not with a lucene-style query string. Is there any way to query data from Elasticsearch using lucene-style query string with Elasticsearch PHP Client API, like (type:apache-access OR type:apache-error)?

I believe that you can do this via the Elasticsearch basic query via uri:

http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-uri-request.html

curl -XGET 'http://localhost:9200/twitter/tweet/_search?q=user:kimchy'

A bit of discussion on it (including the fact that it supports Lucene style queries) here:

Querying Basic Queries Using Only the Query String

Basic queries can be done using only query string parameters in the URL. For example, the following searches for text 'hello' in any field in any document and returns at most 5 results:

{endpoint}/_search?q=hello&size=5

Basic queries like this have the advantage that they only involve accessing a URL and thus, for example, can be performed just using any web browser. However, this method is limited and does not give you access to most of the more powerful query features.

Basic queries use the q query string parameter which supports the Lucene query parser syntax and hence filters on specific fields (eg fieldname:value), wildcards (eg abc*) and more.

There are a variety of other options (eg size, from etc) that you can also specify to customize the query and its results. Full details can be found in the ElasticSearch URI request docs.
