And + Or query using elastic search REST API
AND/OR Logic can be applied as a Filter. Filters in elasticsearch will evaluate before a query is executed, so if you need to apply this logic to a call that also contains a string query, it will still be efficient and applicable. As your OR code is evaluating the same...
Getting Parse error for elasticsearch-py
python,elasticsearch,elastic,elasticsearch-py
Your query is almost correct. The error your get states ...Parse Failure [Failed to parse source..., which basically means that your query is ill-formed and doesn't comply to the Query DSL. The range query needs to be combined with the match query (using a bool/must query) and both need to...
Delete records of a certain type from logstash/elasticsearch
You can use the delete by query API to achieve that. For instance, the following command will delete all documents of type nbu_job in the index your_index: curl -XDELETE 'http://localhost:9200/your_index/_query?q=_type:nbu_job' If you need to verify what is going to be deleted with the above command, I suggest you run the...

What are the possible reasons behind the java lang outofmemoryerror java heap space in elasticsearch
java,elasticsearch,out-of-memory
Possible reasons (some of them): putting too much data into that memory, especially because of fielddata (used for sorting, aggregations mostly) configuration mistake, where you thought you set something for heap size, but it was wrong or in the wrong place, and your node starts with the default and that...
ElasticSearch Nest Query with Dynamic Match
There are multiple ways to conglomerate various calls into one call that will return different results depending on boolean inputs. You have 2 variables and 4 different outcomes, you have to implement logic that checks all of these somewhere, so you have build if/elseif/else blocks with the SearchDescriptors, however with...

Elasticsearch geospatial search, problems with index setup
There are a couple issues in your code: Issue 1: When you create your document in the second snippet, you're not using the correct mapping type and your body doesn't include the correct field name as declared in your mapping: client.create({ index: 'events', type: 'geo_point', <-------- wrong type body: {...
Sorting after aggregation in Elasticsearch
sorting,elasticsearch,aggregation
You almost had it. You just need to add an order property to your a1 terms aggregations, like this: GET myindex/_search { "size":0, "aggs": { "a1": { "terms": { "field": "FIELD1", "size":0, "order": {"a2": "desc"} <--- add this }, "aggs":{ "a2":{ "sum":{ "field":"FIELD2.SUBFIELD" } } } } } } ...
Elasticsearch daily rolling index contains duplicate _id
Since you are using multiple indexes, one for every day, you can get the same _id. What makes a document unique is the uid, which is a combination of index,type and id. There is no way in elastic to change this to my knowledge.
Passing Elasticsearch and Kibana config file to docker containers

Query returns both documents instead of just one
term filters don't analyze the text to be searched. Meaning, if you search for 000A8D810F5A, this is exactly what is searching for (upper-case letters included). But, your macAddr and insturmentName fields and others are just strings. Meaning, they use the standard analyzer which lowercases the terms. So, you are searching...
How to write search queries in kibana using Query DSL for Elasticsearch aggregation

Strategy to persist the node's data for dynamic Elasticsearch clusters
elasticsearch,docker,mesos,marathon
Elasticsearch and NFS are not the best of pals ;-). You don't want to run your cluster on NFS, it's much too slow and Elasticsearch works better when the speed of the storage is better. If you introduce the network in this equation you'll get into trouble. I have no...
elasticsearch aggregation group by null key
I don't think you can do this with terms. Try with another aggregation: { "aggs": { "myAggrs": { "terms": { "field": "system" } }, "missing_system": { "missing": { "field": "system" } } } } And the result will be: "aggregations": { "myAggrs": { "doc_count_error_upper_bound": 0, "sum_other_doc_count": 0, "buckets": [ {...

Elasticsearch NumberFormatException when running two consecutive java tests
java,date,elasticsearch,numberformatexception,spring-data-elasticsearch
Since the exception complains about a NumberFormatException, you should try sending the date as a long (instead of a Date object) since this is how dates are stored internally.

You need to re-create the mapping for your index and to re-index all the documents in it. You don't have doc_values enabled for that field: "doc_values": true. But you want your fielddata format to be doc_values. This is not possible. To be able to change the fielddata format from whatever...
Javascript: Altering an object where dot notation is used [duplicate]
javascript,jquery,elasticsearch
This is because the binding you've used (i.e., 'terms.region.slug') is incompatible with dot-notation. Use of dot-notation requires that the binding be parseable as an identifier. However, bracket notation is equivalent to dot-notation and allows any binding to be used. console.log( filter.and[0].term['terms.region.slug'] );...

Use a PHP file to Symfony

Typically this would be done with a use statement near the top of the file (under the namespace declaration for the class), i.e.: namespace MyBundle\Controller use Elasticsearch; class index { public function indexAction() { $client =...
NEST - Using GET instead of POST/PUT for searching
Yes https://github.com/elastic/elasticsearch-net/blob/develop/src/Nest/DSL/SearchDescriptor.cs line number 135 public static void Update(IConnectionSettingsValues settings, ElasticsearchPathInfo<SearchRequestParameters> pathInfo, ISearchRequest request) { pathInfo.HttpMethod = request.RequestParameters.ContainsKey("source") ? PathInfoHttpMethod.GET : PathInfoHttpMethod.POST; } Obviously you need to have SearchRequest.RequestParameters.ContainsKey("source") return true for it to do a Get. In future. Just RTFM....
Elastic4s - finding multiple exact values for one term
When calling termsFilter, the method is expecting a var args invocation of Any*, so termsFilter("category", 1, 2) would work. But termsFilter("category", Array(1,2)) is treated as a single argument, since Array is a subclass of Any of course. By adding : _ * we force scala to see it as a...
How to have multiple regex based on or condition in elasticsearch?
Use a should instead of a must: { "fields": [ "host" ], "filter": { "bool": { "should": [ { "regexp": { "_uid": { "value": ".*000ANT.*" } } }, { "regexp": { "_uid": { "value": ".*0BBNTA.*" } } } ] } } } ...
ElasticSearch + Kibana - Unique count using pre-computed hashes
That error says you don't have enough memory (more specifically, memory for fielddata) to store all the values from hash, so you need to take them out from the heap and put them on disk, meaning using doc_values. Since you are already using doc_values for my_prop I suggest doing the...
