I have a CSV file in which I have a column containing timestamps and a column containing text. I want to be albe to look for occurrences of certain keywords (let's say 10 keywords) and to show the number of occurrences of each keyword on a chart. It would also be good to find a display them over time. What I do not understand is how to search for multiple keywords on this strings while counting the occurrences... can you help me?
Example file (where timestamp represent the day):
20;The quick brown fox jumps over the lazy dog
