What happened?

I am currently testing Smart Search and have added a custom filter.

My setup is as follows:

• A documentation category in com_content
• Akeeba Ticket System (ATS), which provides a Smart Search plugin

Without any filter applied, everything works as expected. Smart Search returns relevant results from both Joomla Articles and ATS tickets.

Since I want to limit the search to specific article categories while still including ATS content, I created a filter and experimented with the Search Types options.

Here are the results:

• When no search type is selected, relevant results are returned correctly.
• When I select Articles and choose the required category, the search behaves as expected and returns only relevant articles from that category.
• When I select Tickets (ATS) only, I correctly see the relevant ATS topics.

However, the issue occurs when I select both Articles and Tickets at the same time and select specific categories for Articles. In this case, the search results do not behave as expected. No content. As soon as I deselect Tickets - the component gives correct result with articles taken from selected categories.

I am not sure whether this is a misconfiguration on my side or a limitation/issue in Smart Search when multiple content types are selected within the same filter.

content maps:

Ticket: 1
Article: 105

Could it be that the filter applies conditions using AND instead of OR between different map groups or content types?

Version

6.1

Expected result

When I search 'Joomla' word, then I expect results within Akeeba Ticket System ('First Ticket') and Articles from DOCS category.

Actual result

There is DOCS category and several articles inside. And there is Akeeba Ticket System which contains 'First ticket' ticket. Since I've selected two types in Smart Search filter - Tickets and Articles, I am expecting Smart Search to display content relevant to the selected sources. But no result at all.
If I deselect specific category of Articles, then Smart Search displays content from Tickets and from all Articles.
So, I am not able to use filtering in combination with 3rd party extension.

I suppose there is a problem with conditions using AND instead of OR between different map groups or content types.

System Information

Joomla 6.1.1, PHP 8.4.22
