# Method name: or(query: WixDataQuery)

# Method package: wixData

# Method menu location: wixData --> WixDataQuery --> or

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

# Method Description:

Adds an `or` condition to the query or filter.

The `or()` function adds an inclusive `or` condition to a `WixDataQuery` or `WixDataFilter`. A query or filter
 with an `or` returns all the items that match the query or filter as defined up to
 the `or` function, the items that match the query or filter passed to the `or`
 function, and the items that match both.

 The collections used by both the initial query and the query passed
 to the `or` function must be the same.

 The 'or()' function is designed to work with 2 or more queries or filters.
 If you use it on its own, it will return all the items in a collection.



# Method Code Examples:

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

## Add an or to a query

```javascript
let newQuery = query1.or(query2);
```

## Create a query, add an or, and run it

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

// ...

wixData.query("myCollection")
  .lt("age", 25)
  .or(
    wixData.query("myCollection")
      .gt("age", 65)
  )
  .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;
  });

  /*
   * For example, results contain items where age is:
   * 18
   * 21
   * 67
   * 90
   *
   * But not items where age is:
   * 25
   * 30
   * 40
   * 65
   */
```
