Open Source Document Management System | OpenKM

I already post 6 .pdf documents and respetives Keyboards.

How I can search documents by Keyboards? And where?

OpenKM Version: 6.3.12 with Community Extension.

And other question. How i can search documents searching by document information?

I has already libreoffice installed, version 6.4.7.2.

In which menu can I do it?

* There's a field in the search for searching by keyword. Simply add a keyword in a document and then try to search in the search panel filling the keyword field with it.
* About searching by content -> start uploading a text file -> wait for some minutes 5-10 and then the document should be available ( the documents are processed in a queue by a cron each 5 minutes ) -> then you should be able to search by content

I upload 3 documents:

Test.pdf -> keyboard -> 123 -> Content -> Test123
Test.txt -> keyboard -> 1234 -> Content -> Test1234
Test.docx -> keyboard -> 12345 -> Content -> Test12345

Find document by keyboard, its working perfect!
When I try search by content I only find .txt file.
.pdf and .docx .. I cannot find.

I check my table "OKM_NODE_DOCUMENT" when i upload a .txt file in column "NDC_TEXT" i have content.
When I upload .pdf or .docx in my "NDC_TEXT" column is null.

Its necessary force system.pdf.force.ocr? Its necessary put value on system.openoffice.dictionary?

system.ocr -> /usr/bin/tesseract ${fileIn} ${fileOut}

system.ocr.rotate -> 0;90;180;270

system.pdf.force.ocr -> X

system.openoffice.dictionary -> ""

How I can Install missing language pack for 'spanish', as I thought it was already installed/included during installation of OpenKM ?

You have started the post with a topic about keywords that seems solved. Please for the other matter open a new post and we'll try to help with it ( about the problem with non txt file indexing and tesseract multilanguage -> please one post for each topic )
