+# Pagination & search
+
+This example builds an articles listing endpoint that supports **offset pagination**, **cursor pagination**, **full-text search**, and **faceted filtering** — all from a single `CrudFactory` definition.
+
+## Models
+
+```python title="models.py"
+--8<-- "docs_src/examples/pagination_search/models.py"
+```
+
+## Schemas
+
+```python title="schemas.py"
+--8<-- "docs_src/examples/pagination_search/schemas.py"
+```
+
+## Crud
+
+Declare `facet_fields` and `searchable_fields` once on [`CrudFactory`](../reference/crud.md#fastapi_toolsets.crud.factory.CrudFactory). All endpoints built from this class share the same defaults and can override them per call.
+
+```python title="crud.py"
+--8<-- "docs_src/examples/pagination_search/crud.py"
+```
+
+## Session dependency
+
+```python title="db.py"
+--8<-- "docs_src/examples/pagination_search/db.py"
+```
+
+!!! info "Deploy a Postgres DB with docker"
+    ```bash
+    docker run -d --name postgres -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=postgres -p 5432:5432 postgres:18-alpine
+    ```
+
+
+## App
+
+```python title="app.py"
+--8<-- "docs_src/examples/pagination_search/app.py"
+```
+
+
+## Routes
+### Offset pagination
+
+Best for admin panels or any UI that needs a total item count and numbered pages.
+
+```python title="routes.py:1:27"
+--8<-- "docs_src/examples/pagination_search/routes.py:1:27"
+```
+
+**Example request**
+
+```
+GET /articles/offset?page=2&items_per_page=10&search=fastapi&status=published
+```
+
+**Example response**
+
+```json
+{
+  "status": "SUCCESS",
+  "data": [
+    { "id": "3f47ac69-...", "title": "FastAPI tips", "status": "published", ... }
+  ],
+  "pagination": {
+    "total_count": 42,
+    "page": 2,
+    "items_per_page": 10,
+    "has_more": true
+  },
+  "filter_attributes": {
+    "status": ["archived", "draft", "published"],
+    "name": ["backend", "frontend", "python"]
+  }
+}
+```
+
+`filter_attributes` always reflects the values visible **after** applying the active filters. Use it to populate filter dropdowns on the client.
+
+### Cursor pagination
+
+Best for feeds, infinite scroll, or any high-throughput API where offset performance degrades.
+
+```python title="routes.py:30:45"
+--8<-- "docs_src/examples/pagination_search/routes.py:30:45"
+```
+
+**Example request**
+
+```
+GET /articles/cursor?items_per_page=10&status=published
+```
+
+**Example response**
+
+```json
+{
+  "status": "SUCCESS",
+  "data": [
+    { "id": "3f47ac69-...", "title": "FastAPI tips", "status": "published", ... }
+  ],
+  "pagination": {
+    "next_cursor": "eyJ2YWx1ZSI6ICIzZjQ3YWM2OS0uLi4ifQ==",
+    "prev_cursor": null,
+    "items_per_page": 10,
+    "has_more": true
+  },
+  "filter_attributes": {
+    "status": ["published"],
+    "name": ["backend", "python"]
+  }
+}
+```
+
+Pass `next_cursor` as the `cursor` query parameter on the next request to advance to the next page.
+
+## Search behaviour
+
+Both endpoints inherit the same `searchable_fields` declared on `ArticleCrud`:
+
+Search is **case-insensitive** and uses a `LIKE %query%` pattern. Pass a [`SearchConfig`](../reference/crud.md#fastapi_toolsets.crud.search.SearchConfig) instead of a plain string to control case sensitivity or switch to `match_mode="all"` (AND across all fields instead of OR).
+
+```python
+from fastapi_toolsets.crud import SearchConfig
+
+# Both title AND body must contain "fastapi"
+result = await ArticleCrud.offset_paginate(
+    session,
+    search=SearchConfig(query="fastapi", case_sensitive=True, match_mode="all"),
+    search_fields=[Article.title, Article.body],
+)
+```
