Odoo-18.0-20251222/attachment_unindex_content/readme/DESCRIPTION.md

This module disables the indexation of attachments content.

Attachment model has a field called 'index_content' where the content of the attachment is read and stored directly in the database. This field is useful in order to search content of a file. But most of cases it is not used, so, you can install this module in order to:

• Avoid Duplicating Data: Because indexation extracts text content from files and put it on the database in order it could be searched, but this implies you have the file data in your filestore directory, and also part (or sometimes all) of that data in your database too.
• Improve Performance: Since not all indexed files are plain text, they require extra process to read them.

Maybe you could try to uninstall modules like document in order to disable its indexation features, but you could face the uninstallation of other modules that could be useful for you (e.g, hr_recruitment depends on that).

But even if you don't have document installed, you'd still have plain text content indexation by default. As you can see in this SQL query results, indexation is active even without it:

Using this module you will not require to uninstall any module to disable the attachment content indexation, because we directly disable it at ir.attachment base.

Also, after the installation, the index_content field on attachments already recorded in database will be cleared.
