Hello,
I need to parse some PDF files to find the most relevant words and trying to find what PDF are talking about.
Those PDF are vendors catalog, I need for example to extract products to propose them in a web search engine (actually powered by Elasticsearch with entities parsed from database).
Some catalogs could also be EXCEL files and those files are not standardized.
I used Elasticsearch a long time ago and I am not a data scientist 🙃
My project uses Elasticsearch as standalone, with a PHP client :
curl -XGET '[http://localhost:9200](http://localhost:9200)'
{
"name" : "n1es6kx",
"cluster\_name" : "elasticsearch",
"cluster\_uuid" : "5ya3CLzuQYKWMtqLk4Libw",
"version" : {
"number" : "6.8.10",
"build\_flavor" : "default",
"build\_type" : "deb",
"build\_hash" : "537cb22",
"build\_date" : "2020-05-28T14:47:19.882936Z",
"build\_snapshot" : false,
"lucene\_version" : "7.7.3",
"minimum\_wire\_compatibility\_version" : "5.6.0",
"minimum\_index\_compatibility\_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
"friendsofsymfony/elastica-bundle": "~5.2",
"ruflin/elastica": "~6.1"
I am currently reading documentation but any advices/recommandations would be useful.
Thank you.

First, upgrade! At least to 7.17.8 but better to 8.5.3.
You can use the [ingest attachment plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/current/ingest-attachment.html).
There an example here: [https://www.elastic.co/guide/en/elasticsearch/plugins/current/using-ingest-attachment.html](https://www.elastic.co/guide/en/elasticsearch/plugins/current/using-ingest-attachment.html)
```auto
PUT _ingest/pipeline/attachment
{
"description" : "Extract attachment information",
"processors" : [
{
"attachment" : {
"field" : "data"
}
}
]
}
PUT my_index/_doc/my_id?pipeline=attachment
{
"data": "e1xydGYxXGFuc2kNCkxvcmVtIGlwc3VtIGRvbG9yIHNpdCBhbWV0DQpccGFyIH0="
}
GET my_index/_doc/my_id
```
The `data` field is basically the BASE64 representation of your binary file.
You can use [FSCrawler](https://fscrawler.readthedocs.io). There's [a tutorial](https://fscrawler.readthedocs.io/en/latest/user/tutorial.html) to help you getting started.

Hello,
Thank you I will check ingest attachment plugin documentation.
Any advice how my search into PDF could be more relevant ? I thought maybe I could count words to find out which words are the most relevant but I don't think it'will be the best solution.
Maybe there is a kind of IA or something ? Or should I parse my PDF first with an other application ?

What do you mean? Do you have an example for this question?
Ideally open a new discussion about it because this one is marked as solved and your original question is not directly related to the new question IMO. 😉
