ATS: Support for "OR" searches in genres / countries and other fields

This is because genres search works as an "and" search not an "or" search. 

For example, if you check both Romance and Comedy, you are searching for titles which have both of these genres -> http://www.imdb.com/search/title?genres=comedy,romance&title_type=feature

When you are searching for five genres, you are asking for titles with all five selected genres NOT any one of the five selected genres.  Very few titles have five genres so this is why your search returns no results. 

This reply was created from a merged topic originally titled ATS: or vs. and & | in advanced IMDb search.

in the advanced search they used to support using the | symbol between genre's in the search.

example: http://www.imdb.com/search/title?count=100&genres=action|adventure|biography|comedy|crime|docume...

now that gives me a an error. If I want to see all the movies in all genre's that meet my criteria I need an OR | not an AND &

please bring this feature back, I used it often. if I select all the genres by checkboxes it only shows me movies that fit all the genres which is NONE.

Please allow multiple "Genre" to be selected in the "Advanced Title Search." 

Example: "Adventure" *OR* "Drama"

(OR logic, rather than AND logic)

It would be great if advanced searches had an "or" option.For instance, right now I can do an advanced title search on films whose genres are "romance" AND "horror," but I can't search for films that are "romance" OR "horror," or "romance" NOT "horror."

Hello,I wanted to search for European comedies of the 1960s, and so had selected several European countries from the Countries box, thinking that the operator in between all selected countries is OR. It turns out it's actually AND, which is why I was getting zero results, since no film was made between ALL of those countries.A good way to improve this search form would be to make the Countries selection box work not just as "all" countries selected (AND operator, as it is now), but also as as "any" country from those selected (OR logical operator).

For everyone, who have the same problem with genres - there is a workaround! Though it's not obvious from the UI, the engine actually supports excluding genres by specifying "!" before them, like "...&genres=drama,!horror&" which would show you all of the drama titles, that are not horrors. In the UI, you can do it only for Documentary and Short genres, but luckily internally it works for all of them. So this way, if you want to search for multiple genres using OR logic, you just need to include all of the other genres with this negative filter, and you will get the desired results.

But for developers, it would be much better if you include this support in the UI - especially considering that you don't need to change anything in back-end. All you have to do, is to include two panels with genre buttons, but make the second add genres to the filter with exclamation mark, so let's hope this issue will be fixed soon.
