Data Type

In value type ranges, [] indicates that the two end values are included while {} indicates that the two end values are not included.
```
    rowkey:[1 TO *] Equal to or greater than 1
    rowkey:[* TO 1]  Equal to or less than 1
    rowkey:[1 TO 10]  1 to 10
```
Single value
```
    rowkey:1 The value is 1.
```

If multiple conditions need to be met, use () to differentiate priorities.

    rowkey:[1 TO *] && externalImageID:1
    (rowkey:[1 TO *] && externalImageID:1) || timestamp:1000 
    rowkey:[1 TO *] && (externalImageID:1 || timestamp:1000)

Non-statement. You need to add brackets before and after a non-statement.
```
    externalImageID:1 && (!rowkey:2)
```
