I am trying to query elastic search in Java using Jest. I am using a query builder to construct the query.
QueryBuilder matchQuery = QueryBuilders.boolQuery()
.must(QueryBuilders.matchQuery("id", "3434"))
.must(QueryBuilders.matchQuery("name", "name"))
.must(QueryBuilders.matchQuery("action", "login"))
.must(rangeQuery);
//i have this map now
Map<String , String> parameters = new HashMap<>();
parameters.put("id", "3433");
parameters.put("name", "name");
parameters.put("action", "login");
It would be great if some one can tell me if this can be constructed dynamically , like the matchQueries. For instance i would have three match queries , but i would have more. I can put my match query attributes in a Map. But if i iterate that how would we can define this boolQuery ? Anyone has any idea on this ?
Looking for something like this
QueryBuilder matchQuery = QueryBuilders.boolQuery()
.must(QueryBuilders.matchQuery(map.key, map.value))
.must(rangeQuery);
but how would i contruct this dynamically ?
You can simply iterate over your map and add each condition to the query, like this:
BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
for(String key : parameters.keySet()){
boolQuery.must(QueryBuilders.matchQuery(key, parameters.get(key)));
}
boolQuery.must(rangeQuery);
