Advanced search syntax for Django Admin that enables powerful filtering capabilities directly from the search bar.

[中文版 说明](README_zh.md)

## Features

- Enhanced search capabilities in Django Admin with advanced syntax
- Support for field-specific searches with various operators
- Case-sensitive and case-insensitive matching options
- Quoted values support for exact phrase matching
- Multiple conditions combination with AND logic
- Seamless integration with existing Django Admin interfaces
- Performance-conscious implementation with database-level filtering

## Requirements

- Python >= 3.12
- Django >= 5.1

Note: This package has been tested specifically on Django 5.1, 5.2 with Python 3.12. While it may work on other versions, compatibility is not guaranteed for versions outside this range.

## Installation

```bash
pip install django-admin-advanced-search
```

## Usage

1. Add `django_admin_advanced_search` to your `INSTALLED_APPS`:

```python
INSTALLED_APPS = [
    ...
    'django_admin_advanced_search',
    ...
]
```

2. Use the advanced search in your admin classes:

```python
from django.contrib import admin
from django_admin_advanced_search.mixins import AdvancedSearchMixin

class MyModelAdmin(AdvancedSearchMixin, admin.ModelAdmin):
    search_fields = ['name', 'description', 'author__name']  # Fields that can be searched
    # Your other admin configuration

admin.site.register(MyModel, MyModelAdmin)
```

## Search Syntax

| Syntax | Description | Example | SQL Equivalent |
|--------|-------------|---------|----------------|
| `field:value` | Case-insensitive contains | `name:john` | `name ILIKE '%john%'` |
| `field:=value` | Case-insensitive exact | `name:=john` | `name ILIKE 'john'` |
| `field:==value` | Case-sensitive exact | `name:==John` | `name = 'John'` |
| `field:!value` | Case-sensitive contains | `name:!john` | `name LIKE '%john%'` |
| `field:*suffix` | Case-insensitive endswith | `name:*son` | `name ILIKE '%son'` |
| `field:!*suffix` | Case-sensitive endswith | `name:!*son` | `name LIKE '%son'` |
| `field:prefix*` | Case-insensitive startswith | `name:john*` | `name ILIKE 'john%'` |
| `field:!prefix*` | Case-sensitive startswith | `name:!john*` | `name LIKE 'john%'` |
| `"quoted values"` | Exact phrase matching | `name:"John Doe"` | `name ILIKE 'John Doe'` |

## Examples

- `title:django*` - Items with titles starting with "django" (case-insensitive)
- `author__name:*smith` - Items by authors whose names end with "smith" (case-insensitive)
- `title:==Learning Python` - Items with the exact title "Learning Python" (case-sensitive)
- `title:"Python Programming"` - Items with titles containing the exact phrase "Python Programming"
- `title:python author__name:john` - Items with titles containing "python" AND authors whose names contain "john"

## Database Collation and Performance Notes

- This package generates database-level filters, ensuring optimal performance
- For case-insensitive operations, the package uses the database's native case-insensitive comparison operators when available
- Make sure your database columns have appropriate collation settings for optimal performance
- Complex searches with multiple fields may generate complex SQL queries; consider adding database indexes on frequently searched fields
- When using related field lookups (e.g., `author__name:john`), ensure foreign key relationships are properly indexed
