Query Examples

Given data like:

{
"symbol": "ID_42140878",
"timestamp": 1766358000000000,
"sequence": 0,
"price": 6905.75,
"open": 6906.25,
"high": 6910,
"low": 6900.5,
"close": 6905.75,
"volume": 0,
"date": "2025-12-21T23:00:00.000Z",
"chartId": "ID_42140878_volume_20000"
}


You can write queries like:

Simple equality:

symbol = 'ID_42140878'


Date range:

date >= '2025-12-01' and date < '2025-12-15'


Troubleshooting

• No databases found: Make sure you're on a page that uses IndexedDB
• Permission denied: Some websites may have strict Content Security Policies
• Extension not loading: Check the Browser Console (Ctrl+Shift+J) for errors

Multiple conditions with AND:

symbol = 'ID_42140878' and date >= '2025-12-01' and date < '2025-12-15'


Numeric comparisons:

price > 7000 and volume < 1000


BETWEEN operator:

price between 6800 and 6900


Complex query with date range and price range:

date >= '2025-11-01' and date < '2025-12-01' and price between 6800 and 6900


OR operator:

price > 7000 or volume > 10000


Nested properties (dot notation):

user.name = 'John' and user.age >= 18


Supported Operators

• Comparison: =, !=, <>, >, <, >=, <=
• Logical: AND, OR
• Range: BETWEEN x AND y

Data Types

The query parser automatically handles:
- Strings: Enclosed in single or double quotes ('value' or "value")
- Numbers: Plain numeric values (123, 45.67)
- Booleans: true, false
- Null: null
- Dates: Strings that can be parsed as dates are automatically compared as dates
