Hi Radovan,

I had a similar problem in my company. I partially solved it by developping some module like https://github.com/grap/grap-odoo-incubator/tree/12.0/multi_search_product
Basically, I say to the user to don't enter special char.
In your exemple, searching "CD*12345" will return all product containing "CD" and "12345" in any order.

Maybe it can help you.

Note : the wildcard caracter "*" is a global setting that can be changed.

Kind regards.

Well if you can't use trigram, you need to suffer the performance penalty of using Btree indexes for openended text searches. You could partially mitigate by sanitizing to just lowercase and using a like search rather than ilike but probably only worth it for 25k+ products by the time you massage inputs.

But odoo.sh lets you connect via psql, so you can try. pg_trgm is bundled in contrib, same as pg_unaccent so should be there. Just whether you have rights to create extensions.

Graeme,

thanx for input. This part of your email caught my attention:

Stored computed sanitized code - no problem. I can do that and had that in 
mind.

Sanitize search args on way in - you say search for bank accounts shows how to 
do this? Will check that out.

Trigram index that stored field - I am on odoo.sh not sure if that is possible 
there. However if I am able to sanitize both stored code and input that should 
generally be enough. I am looking specifcally to work with internal reference 
(default_code) so no need to handle cases like "Red Cat" or "Cat Red" although 
it would nice also.

Best regards
