-With `case_sensitive: false`, filtering for "john" would match "John", "JOHN", "john", etc.
+### SQL behavior examples
+
+Given a filter value `jes` on a dimension like `customers.first_name`:
+
+- With `case_sensitive: true` (default), generated SQL uses case-sensitive matching, for example:
+
+```sql
+("customers"."first_name") LIKE '%jes%'
+```
+
+- With `case_sensitive: false`, generated SQL normalizes both sides for case-insensitive matching:
+
+```sql
+UPPER("customers"."first_name") LIKE UPPER('%jes%')
+```
+
+So with `case_sensitive: false`, filtering for `john` would match `John`, `JOHN`, `john`, etc.
 
 <Info>
   Dimension-level `case_sensitive` settings override explore-level and project-level settings. See [Tables reference](/references/tables#case-sensitive) for explore-level configuration and [lightdash.config.yml reference](/references/lightdash-config-yml#defaults-configuration) for project-level defaults.
