files indexing automatically by elasticsearch - elasticsearch

I am a newbie in elasticsearch, please forgive me if my question sounds weird :D
I want to index files in some directories with elasticsearch automatically (for example: if i add a file in certain directory then elasticsearch can index that file immediately), but i don't know how to configure elasticsearch in order to solve that problem.
Can anyone suggest me?
Thank in advance

I dont think you can have elasticsearch watch a directory (I wouldn't think that is a good thing to do in most cases.)
Instead, have a client wrapper that implements a FileWatcher. Push changes to ElasticSearch via this client.
You could use PathHierarchyTokenizer to preserve the file system hierarchy in your index, allowing you to drill down your Directory structure.

Where can we create queries in Kibana dashboard

If we need to create queries in Kibana dashboard without creating any codebase change where can we do it. Is there any place to create queries in Kibana. Please tell me anyone who knows that place. Because I have a big problem in our project, creating a dashboard for the logs.
see either https://www.elastic.co/guide/en/kibana/current/kuery-query.html or https://www.elastic.co/guide/en/kibana/current/lucene-query.html

Elasticsearch index a file automatically

I am new to elasticsearch,this question might look weird but is it possible to index a file automatically (i.e given a file path, elasticsearch should index the contents of it automatically).I have got some open source tool like elasticdump and tried using it for the purpose,but I prefer some plugins of elasticsearch which can support almost all elasticsearch versions.. Can anyone suggest me?

Elastic search next steps

I'm new to elasticsearch and am still trying to set it up. I have installed elasticsearch 5.5.1 using default values I have also installed Kibana 5.5.1 using the default values. I've also installed the ingest-attachment plugin with the latest x-pack plugin. I have elasticsearch running as a service and I have Kibana open in my browser. On the Kibana dashboardI have an error stating that it is unable to fetch mappings. I guess this is because I havn't set up any indices or pipelines yet. This is where I need some steer, all the documentation I've found so far on-line isn't particularly clear. I have a directory with a mixture of document types such as pdf and doc files. My ultimate goal is to be able to search these documents with values that a user will enter via an app. I'm guessing I need to use the Dev Tools/console window in Kibana using the 'PUT' command to create a pipeline next, but I'm unsure of how I should do this so that it points to my directory with the documents. Can anybody provide me an example of this for this version please.
If I understand you correctly, let's first set some basic understanding about elasticsearch:
Elasticsearch in it's simple definition is a "Search engine". so you need to store some data, and then elastic will help you to search using a search criteria, and it will retrieve relevant data back
You need a "Container" to save your data to, and elastic has this thing like any database engine to store your data, but the terms are somehow different. for example a "Database" in sql-like systems is called "Index", and what you know as "table" is called "Type" in elastic.
from my understanding, you will need to create your index (with or without mappings) to have a starting point, and I recommend you to start without mappings just to "start" and get things working, but later on it's highly recommend to work with "mappings" if applicable, because elastic is smart, but it cannot know more about your data than you do
Because Kibana has failed to find a proper index to start with, it has complained and asked you to either provide a syntax for index names, or a specific index name so it can infer the inline mappings and give you the nice features of querying, displaying charts, etc of your data, so once you create your index, you will provide that to the starting page of Kibana, and you will be ready to go.
Let me know if you need something more specific to your needs :)

Document Management/Content Management with Search

I have a requirement for a document management system to handle pdf,word,xls,ppt with semantic search.
I started looking into elasticsearch for the same and stumbled on Apache JacKrabbit and subsequently on OpenKM and Hippo. Even though core features like versioning exists in Jackrabbit, I need some pointers on how to go about this.
I need help navigating through the following concerns:
Should I just use elasticsearch and elasticsearch attachment plugin or use Jackrabbit with MySQL backend and use Elasticsearch to index the documents.
Or should I use OpenKM?
Any pointers would be greatly appreciated. This would finally require App integration.
Update Logically, using ElasticSearch for Search makes sense. But I figure that I cannot use that as primary datasource. What are the best options from storage(primary) Apache JackRabbit with MySQL? As all features are prebuilt in OpenKM, would this be a better option?.
What is it you want to achieve? Are you looking to manage making the documents available, is it about managing the content in documents? ES, or any search engine, is generally not a primary data source.
I can't give you any advice wrt OpenKM (neither for or against). Whether Hippo is a match depends on your case which I need to know more about.

Where are all the ElasticSearch Config Params listed?

I'm messing around with a lot of the elastic search configuration parameters in the elasticsearch.yml file. I keep finding gems of knowledge on blog pages enumerating new configuration parameters. Is there a list someplace that enumerates all of them?
Thanks
