I need a bit of advice on a method of showing related articles other than using the Similar module and any input will be greatly appreciated.
I need to be able to manually enter keywords for an article. These keywords should not be categories as I do not want them as part of the taxonomy. I just want to be able to enter keywords either by selecting them from a drop down or typing them in. Then when a person views the node it would automatically show links to other nodes with similar keywords (preferably based on how many keywords in common but not necessary).
The reason I do not want to use Free Tagging for this (as I have seen recommended in other threads) is because there could be dozens of keywords and I do not want the keywords visible to the user anywhere. I just want one category listed and a nice clean page, plus my vocab/terms are complex enough already without throwing hundreds of other things into them.
I am assuming there must be a module that can do this but I am simply unable to find it. I am using Drupal 4.7.
Basically I want something like this:
An article on how a fight broke out and the Cubs vs White Sox's game may be tagged with keywords such as:
Chicago, Cubs, Whitesox, Fight, Suspension, Baseball, mlb, Interleague, Player A, Player B, Player C, Rivalry.
After the keywords are filled out I would want to show, somewhere on this nodes page, articles to other fights in sports, other articles about the teams, players, inter-league play, etc.
