Query Examples

Given data like:

<code>{
  "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"
}
</code>

You can write queries like:

<strong>Simple equality:</strong>

<code>symbol = 'ID_42140878'
</code>

<strong>Date range:</strong>

<code>date &gt;= '2025-12-01' and date &lt; '2025-12-15'
</code>

Troubleshooting
<ul><li><strong>No databases found</strong>: Make sure you're on a page that uses IndexedDB</li><li><strong>Permission denied</strong>: Some websites may have strict Content Security Policies</li><li><strong>Extension not loading</strong>: Check the Browser Console (Ctrl+Shift+J) for errors</li></ul>
<strong>Multiple conditions with AND:</strong>

<code>symbol = 'ID_42140878' and date &gt;= '2025-12-01' and date &lt; '2025-12-15'
</code>

<strong>Numeric comparisons:</strong>

<code>price &gt; 7000 and volume &lt; 1000
</code>

<strong>BETWEEN operator:</strong>

<code>price between 6800 and 6900
</code>

<strong>Complex query with date range and price range:</strong>

<code>date &gt;= '2025-11-01' and date &lt; '2025-12-01' and price between 6800 and 6900
</code>

<strong>OR operator:</strong>

<code>price &gt; 7000 or volume &gt; 10000
</code>

<strong>Nested properties (dot notation):</strong>

<code><a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/330f4f94ee1c6a143e09308c914dac27641291de8ddc58baea6257a74a992b9c/http%3A//user.name" rel="nofollow">user.name</a> = 'John' and user.age &gt;= 18
</code>

Supported Operators
<ul><li><strong>Comparison:</strong> <code>=</code>, <code>!=</code>, <code>&lt;&gt;</code>, <code>&gt;</code>, <code>&lt;</code>, <code>&gt;=</code>, <code>&lt;=</code></li><li><strong>Logical:</strong> <code>AND</code>, <code>OR</code></li><li><strong>Range:</strong> <code>BETWEEN x AND y</code></li></ul>
Data Types

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