Adding Filters

Key	Action
a	Add new WHERE filter
d	Delete current WHERE filter

Filter Fields

Each WHERE filter has four components:

1. Field - The document field to filter on (e.g., status, age, createdAt)
2. Operator - Comparison operator (opens popup selector)
3. Type - Value type (auto-detected or manual)
4. Value - The value to compare against

Operators

Operator	Description
==	Equal to
!=	Not equal to
<	Less than
<=	Less than or equal
>	Greater than
>=	Greater than or equal
in	Value in array
not-in	Value not in array
array-contains	Array contains value
array-contains-any	Array contains any of values

Value Types

Type	Description
auto	Auto-detect type from value
string	Text value
integer	Whole number
double	Decimal number
boolean	true/false
null	Null value
array	Array (for in, not-in, array-contains-any)

ORDER BY

Set the field to sort results by and the direction:

• ASC - Ascending (smallest first)
• DESC - Descending (largest first)

LIMIT

Maximum number of documents to return (default: 50).

Executing Queries

Press Enter on the Execute button to run the query.

Top-level Collection Query

Results replace the entire tree view.

Subcollection Query

Results appear under the subcollection node in the tree, preserving the rest of the tree structure.

Clearing Queries

Press Enter on the Clear button to reset all filters, ORDER BY, and LIMIT to defaults.

Examples

Find Active Users

WHERE: [status] [==] (string) [active]

Find Users Over 18, Sorted by Age

WHERE: [age] [>] (integer) [18]
ORDER BY: [age] [ASC]

Find Recent Orders

WHERE: [createdAt] [>] (auto) [2024-01-01]
ORDER BY: [createdAt] [DESC]
LIMIT: [100]

Tips

• Use auto type for most values - it will detect strings, numbers, and booleans
• For date fields, enter ISO format dates as strings
• Firestore requires composite indexes for some query combinations
• If a query fails, check the error message for index requirements
