Use Elasticsearch FIlter JSON directly in JAVA Api

Hi All,

I am passing the JSON String to wrapperFilter method.

FilterBuilder filterBuilder = FilterBuilders.wrapperFilter("{"filter":
{"and"=[{"term":{"c24":TEXT} }, {"term":{"C25":text} }]} }");

FilteredQueryBuilder qb = QueryBuilders.filteredQuery(queryBuilder,
filterBuilder);

System.out.println("Query : " + qb);

SearchResponse searchResponse = null;
// SortBuilder sort=SortBuilders.fieldSort("c0").order(SortOrder.DESC);
searchResponse = client.prepareSearch("ipdr").addField("c0")
.setQuery(qb).setSize(10000)
.setSearchType(SearchType.QUERY_THEN_FETCH).execute()
.actionGet();
for (SearchHit hit : searchResponse.getHits()) {

try {
System.out.println(hit.getFields().get("c0").getValue()
.toString());
} catch (Exception e) {
e.printStackTrace();
}
}

But, ES will internally fire following query to fetch records:

{
"filtered" : {
"query" : {
"match_all" : { }
},
"filter" : {
"wrapper" : {
"filter" :
"eyJmaWx0ZXIiOiB7ImFuZCI9W3sidGVybSI6eyJjMjQiOlRFWFR9IH0sIHsidGVybSI6eyJDMjUiOnRleHR9IH1dfSB9"
}
}
}
}

Can you guide me to sort out the issue.

Thanks,
Ankit Jain

I find it's much better and easier to create searches in Java (you're doing
that) and then use Java all the way and not try to create JSON (the hard
way) or try to create Java-escaped JSON string (the really really hard way).

Start with the JavaDoc at http://es-java-doc.medcl.net/

Look at the static methods of the QueryBuilders and FilterBuilders classes.
They'll create your query and filter terms as needed. This is much easier.

The create an option in your application to call the root query's (or
filter's) toString method to create the JSON string for posting to this
newsgroup.

But do the work in Java all the way, and you'll find it much easier.

Hope this helps!
