I have a field in elasticsearch index with a mp3 filename, i want to create a custom field that shows a player with a formatted url and adding the filename stored in elasticsearch. Is it possible to do it?
You need to create a scripted field : https://www.elastic.co/blog/kibana-4-beta-3-now-more-filtery
Something like that "url/"+doc["filename"].value

I am new to apache NiFi.
I am trying to put data into elasticsearch using nifi.
I want to specify an index name by combining a specific string and the value converted from a timestamp field into date format.
I was able to create the desired shape with the expression below, but failed to create the index name with the value of the timestamp field of the content.
${now():format('yyyy-MM-dd')}
example json data
{
"timestamp" :1625579799000,
"data1": "abcd",
"date2": 12345
}
I would like to get the following result:
index : "myindex-2021.07.06"
What should I do? please tell me how
I know that if you use the PutElasticSearch Processor, you can provide it with a specific index name to use. And as long as the index name meets the proper ElasticSearch format for naming a new index, if the enable auto index creation in ElasticSearch is turned on, then when sent, Elastic will create the new index with the desired name. This has worked for me. Double check the Elastic Naming Rules that can be found here or https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/es-indexing.html
I am using Kibana scripted fields using painless to populate a URL like this:
Url Template : https://dummy_url?branch={{value}}&id=abc
Script:
if (!doc['branch_name'].empty) {
return (doc['branch_name'].value)
}
When I access this scripted field for my index pattern in Discover, the value gets populated correctly and I can access the URL but when I am accessing the same scripted field in "data table" Visualize, the URL is missing the value populated by {{value}}.
Already tried using {{rawValue}} and doc['branch_name.keyword'] but none worked.
Can you please help on how I can populate the scripted field correctly on data table visualize?
I am using Kibana Version, 5.4.1.
The doc has values like this:
branch_name
develop
master
release/f1
release/f2
I am using elastic search 7.10.1. I would store and search against my blogs. The blog has id,title and content fields.
I would like to search against id, title and content, but since the content of blog is too big, so that I would like to save the original content text outside of Elastic Search, such as HBase.
I would ask how to achieve this in ES?
If you are using a static mapping then simply don't define your content field in your index mapping, and don't populate it while indexing your document to ES.
Refer to Mapping param for more info, and specifically, store param default false which means you can't retrieve field value if _source(true by default) is also disabled.
index param default true, which controls whether the field is searchable or not, in your case if you don't want to search and retrieve it you have to disable these two params.
Is there a way i can change only the name of a scripted field? I'm using Kibana 4.3.0. For eg. I want to rename Bytes Read(GB) to Bytes Read. When i click on edit field, it doesn't allow name changes.
You can not change the name of a scripted field, you only can copy the script and paste in a new scripted field with the new name.
I had indexed the document and I am able to search content of document.
But I want to find the type of document is indexed, author of document , name of document, size of document basically properties of file.
How it can be achieved with the help of elasticsearch.
Thank You.
Use elastic search head to take a look at the index tika generated in ElasticSearch for you
http://mobz.github.io/elasticsearch-head/
Then you can search on those fields by using queries like author:Lav (assuming you found a field named author in your index)
