How to ingest .doc / .docx files in elasticsearch? - elasticsearch

I'm trying to index word documents in my elasticsearch environment. I tried using the elasticsearch ingest-attachment plugin, but it seems like it's only possible to ingest base64 encoded data.
My goal is to index whole directories with word files. I tried using FSCrawler but it sadly currently contains a bug when indexing word documents. I would be really thankfull if someone could explain me a way to index directories containing word documents.

Tokenizing the documents already indexed in an elastic search index

I have some documents stored inside my index in elasticsearch. I want to analyze the documents stored inside that index through a custom-made elasticsearch plugin.
I tried doing this task using the term_vectors API but, got no luck.
Is there any way to analyze the indexed documents without updating the index mapping?

Is there some way to get elasticsearch index data from RAM?

I have 60gb text file and I want to search by text field in it. My plan is to put the file into Elasticsearch and setup search there.
But it might be that searching in text file would by quicker if reading file from RAM.
So the question is: Is there some way to read Elasticsearch index from RAM and search in RAM. It helps me to compare speed of searching into Elasticsearch and searching into text file(json,.pickle of other format).
I tried to read from the .pickle file using python.
The version of Elasticsearch is 7.1.
No, it is not. In the first versions of ES (see https://www.elastic.co/guide/en/elasticsearch/reference/1.4/index-modules-store.html) it was possible, but not anymore. You should rely on ES to cache the contents that are more frequently used, but there is nothing you can do to tell it to store contents in memory.

Indexing .png/JPG/PDF files in elastic search from fileserver

Am having search based requirement. Am able to do indexing oracle database tables into elasticsearch by using logstash. In the same way, i have to index png/JPG/PDF files which are all presented in fileserver now.
Am using elasticsearch version 6.2.3. Can anyone have any idea about indexing files from fileserver to elasticsearch ?
purpose - why am seeing for indexing png/JPG/PDF :
i have to search and display some products with product information, along with that i have to display product picture also which is stored in fileserver.
I have a feature to search for documents (pdf). so,if is search with any keywords, it should also search in the contents of the documents and bring those document as search results. Here documents filepath is available in DB only files are available in fileserver.
For these two purpose, am looking for indexing png/JPG/PDF files.
You just have to get bytes from your image(you can do it in any program language) and then save them in field with binary type. But it is not a good idea, try to save the link to the image.

Index existing documents on startup

I'm new to elasticsearch and this is a question I've been trying to find an answer to. Basically I have around a thousand documents that I would like elasticsearch to index for me. Do I have to write a bash/python script that would just use CURL to put/post all these documents in my elasticsearch server or can I configure my server so that it would automatically index documents in a specific folder/location on disk when I start it up for the first time?
I far as I know Elasticsearch does not have any option for pulling document to index itself. As you mentioned you need to create a script and push your documents to ES yourself.

How to use Elasticsearch to make files in a directory searchable?

I am very new to search engines and Elasticsearch, so please bear with me and apologies if this question sounds vague. I have a large directory with lots of .csv and .hdr files, and I want to be able to search text within these files. I've done the tutorials and read some of the documentation but I'm still struggling to understand the concept of indexing. It seems like all the tutorials show you how to index one document at a time, but this will take a long time as I have lots of files. Is there an easier way to make elasticsearch index all the documents in this directory and be able to search for what I want?
Elasticsearch can only search on documents it has indexed. Indexed means Elasticsearch has consumed a document one by one and stored it internally.
Normaly internal structure matters and you shold understand what you're doing to get best performance.
So you need a way to get your files into elastic search, I'm affraid there is no "one click way" to achieve this...
You need
Running cluster
Designed index on for the documents
Get document from filesystem to Elasticsearch
Your question is focused on 3).
For this, search for script examples or tools that can crawl your directory and provide Elasticsearch with documents.
5 seconds of using Google brought me to
https://github.com/dadoonet/fscrawler
https://gist.github.com/stevehanson/7462063
Theoretically it could be done with Logstash (https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html), but I would give fscrawler a try.
