Hi,

i need to create filter or search module for searching articles with multi criteria keywords. Each article will have some keywords or custom fields in to article manager where I put some keywords. For example: customer will search for breed dogs with multiple criterias,.... so he will select between 4 and 20 check boxes with this criteria and if there is matching at least 4 criteria then it shows some search results if not must see a warning...

Does it make sense?

p.s. Sorry for my bad english:)

Hi and welcome, mosquito12!

Your best bet would be to use Fabrik:
extensions.joomla.org/extensions/contact...-feedback/forms/1659

It's extremely powerful at building custom forms that leverage tables from the database. Here are our tutorials on it to give you a good idea:

www.ostraining.com/blog/joomla/joomla-user-list/
www.ostraining.com/blog/joomla/fabrik-user-registration-form/

Also, here's their wiki page with their documentation:
fabrikar.com/wiki/index.php/Main_Page

Alternatively, you might consider hiring a developer to get this done for you since it's a complicated task. On the following page you can see our list of recommended developers:

Hope this helps! :)

Kind regards,
