Hey, I finally fixed the issue I was having while importing from csv.
Your plugin ignores the first and the last values for brands of each product in the row, when it's like this:
NIGHT RUNNER | MAMBO MIX | BLACK KS | JOOP | FERRARI PASSION
Then i fixed this by adding | in front of the first and the last keywords, like this:
| NIGHT RUNNER | MAMBO MIX | BLACK KS | JOOP | FERRARI PASSION |
An now, the plugin can find them.
All of this is when using: regular engine, with AND exact word matching.
Maybe you should fix this for a future version.
