Hi, @toderesa97. You can use it like this;
```
scala> Seq("abc", "def").toDF("v").write.saveAsTable("t")
scala> sql("SELECT * FROM t WHERE v LIKE '%bc'").explain()
== Physical Plan ==
*(1) Project [v#18]
+- *(1) Filter (isnotnull(v#18) AND EndsWith(v#18, bc))
^^^^^^^^
+- *(1) ColumnarToRow
+- FileScan parquet default.t[v#18] ...
scala> sql("SET
spark.sql.optimizer.excludedRules=org.apache.spark.sql.catalyst.optimizer.LikeSimplification")
scala> sql("SELECT * FROM t WHERE v LIKE '%bc'").explain()
== Physical Plan ==
*(1) Project [v#18]
+- *(1) Filter (isnotnull(v#18) AND v#18 LIKE %bc)
^^^^
+- *(1) ColumnarToRow
+- FileScan parquet default.t[v#18] ...
```
