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

# Method package: wixData

# Method menu location: wixData --> WixDataFilter --> contains

# Method Link: https://dev.wix.com/docs/velo/apis/wix-data/wix-data-filter/contains.md

# Method Description:

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

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

 You can use `contains()` with a property whose value is a String or a Reference.
 For properties of type reference it is recommended that you use the [`eq()`](#eq)
 function instead of `contains()`. With properties that are References, `contains()`
 matches by the ID of the referenced item as 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
let newQuery = query.contains("description", "some words");
```

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

```javascript
import wixData from 'wix-data';

// ...

wixData.query("myCollection")
  .contains("description", "some words")
  .find()
  .then((results) => {
    if(results.items.length > 0) {
      let items = results.items;
      let firstItem = items[0];
      let totalCount = results.totalCount;
      let pageSize = results.pageSize;
      let currentPage = results.currentPage;
      let totalPages = results.totalPages;
      let hasNext = results.hasNext();
      let hasPrev = results.hasPrev();
      let length = results.length;
      let query = results.query;
    } else {
      // handle case where no matching items found
    }
  })
  .catch((error) => {
    let errorMsg = error.message;
    let code = error.code;
  });
```

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

```javascript
import wixData from 'wix-data';

// ...

wixData.query("myCollection")
  .contains("description", "some words")
  .gt("age", 25)
  .ascending("last_name", "first_name")
  .limit(10)
  .find()
  .then((results) => {
    if(results.items.length > 0) {
      let items = results.items;
      let firstItem = items[0];
      let totalCount = results.totalCount;
      let pageSize = results.pageSize;
      let currentPage = results.currentPage;
      let totalPages = results.totalPages;
      let hasNext = results.hasNext();
      let hasPrev = results.hasPrev();
      let length = results.length;
      let query = results.query;
    } else {
      // handle case where no matching items found
    }
  })
  .catch((error) => {
    let errorMsg = error.message;
    let code = error.code;
  });
```
