I am taking an example from the Fabrik wiki: http://site.com/mypage? tablename___user_town[value]=La Rochlle &tablename___user_town[value]=Paris &tablename___user_town[join]=OR &tablename___user_town[condition]=CONTAINS It's clear that I am trying to search for values 'La Rochlle' and 'Paris' in the table 'tablename' under the column 'user_town'. Let's expand this a bit now and say I am trying to search for 75 different 'user_town' instead of just the 2 towns as above. Out of those 75 towns, only 70 of them are present under the 'user_town' column and the other 5 are not. The search result will return the list of those 70 towns that are present under 'user_town'. The issue here is how would I know which 5 towns were not found during the search. It is not practical to go through the returned list and look through each column one by one. If my explanation is not clear enough please message to explain in more detail. Any help/ideas would be highly appreciated.
