Attachment Unindex Content

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.
