# Method name: contains(propertyName: string, string: string)

# Method package: wixPricingPlansBackend

# Method menu location: wixPricingPlansBackend --> PublicPlansQueryBuilder --> contains

# Method Link: https://dev.wix.com/docs/velo/apis/wix-pricing-plans-backend/public-plans-query-builder/contains.md

# Method Description:

Refines a query to match items whose specified property value contains a specified string.

The `contains()` function refines a `PublicPlansQueryBuilder` to
 only match items where the value of the specified property contains the
 specified `string`. Matching with `contains()` is case-sensitive, so
 `"TEXT"` does not contain `"text"`.  

 You can only use `contains()` with a property whose value is a String.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## Add a 'contains' filter to a query

```javascript
const newQuery = wixPricingPlansBackend.queryPublicPlans().contains("slug", "free");
```

## Create a query, add a 'contains' filter, and run it

```javascript
import wixPricingPlansBackend from 'wix-pricing-plans-backend';

// ...

wixPricingPlansBackend.queryPublicPlans()
  .contains("slug", "free")
  .find()
  .then((results) => {
    if (results.items.length > 0) {
      const items = results.items;
      const firstItem = items[0];
      const totalCount = results.totalCount;
      const pageSize = results.pageSize;
      const currentPage = results.currentPage;
      const totalPages = results.totalPages;
      const hasNext = results.hasNext();
      const hasPrev = results.hasPrev();
      const length = results.length;
      const query = results.query;
    } else {
      // handle case where no matching items found
    }
  })
  .catch((error) => {
    const queryError = error;
  });
```
