Hi,
In Virtual DataPort, 'Like' and 'Contains' are Comparison Operators that are used to perform pattern matching in a query.
* Like Operator : You could display the values with specified pattern with wildcard characters (% and _).
For example, executing the below query would return the results with field containing the text input1 and input2.
```
Select * from view where field like '%input1%' or field like '%input2%'
```
* Contains operator : You could retrieve the values using external index of an unstructured data sources. It is supported in Aracne and Google Search data sources.
For example, executing the below query would return the results with field containing the text input1 and input2.
```
Select * from view where field contains 'input1 AND input2’
```
For more information on **like** and **contains** operator, have a look at [Comparison Operators ](https://community.denodo.com/docs/html/browse/6.0/vdp/vql/language_for_defining_and_processing_data_vql/comparison_operators/comparison_operators#comparison-operators)of the Virtual DataPort VQL Guide.
Hope this helps you.
