Hello,
I have a list & search type with a generic search field which searches different fields. Now I have an external calendar script (in the same database) with date values. Each content entry in Seblod is connected over an calendar_id field with a specific calendar. Now I want to filter the search list (additional) with the calender date (give me all entries from my content which fit the generic search + the calendar has no entry for this day (or better an range of days)). In general I have no problems to work with SQL etc. so it's not the problem to expand the given query from Seblod. My question is:
Do I have to code a new search field which searches the other tables or is it possible to use e.g. the calendar field in Seblod, force the field _not_ to search Seblod entries and write a small plugin where I can append the additional query filter.
Thank you for any ideas and help :)
Best regards.
Edit: Updated the description what i wanna do:
Find all entries which has no calendar entries for a given range of dates (while the dates are in a 3rd party extension table)
