think it worked
I think your corrections worked. I am getting results that seem to occur with more than one keyword. I am not putting commas between keywords right now, just spaces. it did not work if I happened (as a user) to put in commas in the input field. I will have to rest the results more to make sure I am pulling the correct rows given multiple keywords.
Now I need to work on the concat and multiple ways of searching.
1. someone may just use a category dropdown and pull all the drills in a certain category. Not all the categories are similar to keywords.
2. the filtering type functionality I mentioned in which I might choose a category or keyword + number of players required for a drill.
