How to query with JSON when use Java API in ElasticSearch?

Elastic Stack Elasticsearch
1

Hi all,
I'm using ElasticSearch as a search service in Spring Web project. Now
I'm using Transport Client to communicate with ES.
I'm wondering if there exists a method which can construct a QueryBuilder
from a JSON DSL. for example, convert this bool query DSL JSON
{
"query" : {
"bool" : {
"must" : { "match" : {"content" : "quick"},
"should": { "match": {"content" : "lazy"}
}
}
}

to a QueryBuilder. I need this function because I have to receive

user's bool string input from web front-side, and parse this bool string to
a QueryBuilder.
However it not suit to use
QueryBuilders.boolQuery().must(matchQB).should(shouldQB).must_not(mustNotQB).
Because we may need several must or non must keywords.

Thanks for your time! I'm really need some help.

Hi,

there are QueryBuilder that can parse JSON, e.g. WrapperQueryBuilder
http://javadoc.kyubu.de/elasticsearch/HEAD/org/elasticsearch/index/query/WrapperQueryBuilder.html wrapperQuery(java.lang.String source).
This should do the job.

Greets,

PS: Still wondering why javadocs disappeared a while ago. This would be a
great help if javadocs would be available for each version for download.

Hi Andrej,
Thanks a lot for your kindly help. It's really give me a big progress.
PS: I also found that QueryBuilders.wrapperQuery(String DSL) can do the
same
work. How to construct QueryBuilder from JSON DSL when using Java API in ElasticSearch? - Stack Overflow
