Reply To: How to i highlight the matched keyword?

As you can see in the attachment, i have “Primary Description Field for Posts/Pages/CPT” filled with “car_type” where car type is something like “Brio CBU DD2 1.3, Brio Satya DD1, Brio Satya New DD1, City GD8 IDSI, City GD8 VTEC, Civic Estilo SR3, Civic Genio SR4, Jazz GD3 IDSI, Jazz GD3 VTEC”

1. How can this (“Brio”) not be found?
2. How the plugin determines which to show between PRIMARY and SECONDARY description?
