# Contains
The **Contains** function searches for a specified substring in a text value. If the substring is found, the function returns `True`, otherwise it returns `False`.
### Syntax
```
Contains(string, substring...)
```
Function arguments:
| | |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **string** |
A text value or column of text values to search.
Individual text value input (not column input) must be enclosed in parentheses. For example, "My name is Bob".
Can only reference a column that contains text data.
|
| **substring...** |
One or more substrings or columns of substrings to search for in the text value.
Individual substring input (not column input) must be enclosed in parentheses. For example, "is Bob".
Multiple substrings must be input as separate arguments. For example, "name", "is Bob" or \[ColumnA], \[ColumnB].
|
### Notes
* Arguments are case sensitive. To bypass case sensitivity, use the [lower](https://support.meetuma.ai/uma-knowledgebase/data-and-reporting/analytics-pro/functions/text-functions/lower "mention") function to convert the arguments to lowercase as needed.
* When the multiple substring arguments are included, the function returns `True` if at least one substring is found.
### Examples
#### Example 1
```
Contains("Welcome to Sigma", "to sig")
```
Returns `False` because "to sig" (with a lowercase 's') isn't a substring in "Welcome to Sigma."
#### Example 2
```
Contains(Lower("Welcome to Sigma"), "to sig")
```
Converts the **string** argument to all lowercase characters and returns `True` because "to sig" is found as a substring in "welcome to sigma."
#### Example 3
```
Contains([Station], [City])
```
Returns `True` when the city name (text value in the *City* column) is found as a substring in the station name (text value in the *Station* column). Otherwise, the function returns `False`.
#### Example 4
```
Contains([Product Name], "Digital Camera", "DSLR")
```
Returns `True` when either "Digital Camera" or "DSLR" is found as a substring in the product name (text value in the *Product Name* column). Otherwise, the function returns `False`.
