Frappe Search System

Four Search Subsystems

frappe.desk.search

frappe.utils.global_search

frappe.search.full_text_search

frappe.search.sqlite_search

Decision Tree

What search do you need?
│
├─ Link field autocomplete (user types in a Link field)?
│  ├─ Default behavior sufficient → Configure search_fields on DocType
│  └─ Custom logic needed → standard_queries hook or query parameter
│
├─ Cross-doctype search (user searches for anything)?
│  ├─ Desk users → Global Search (auto-enabled)
│  │  └─ Set in_global_search=1 on important fields
│  └─ Website visitors → web_search() or WebsiteSearch (Whoosh)
│
├─ Custom full-text search for your app [v15+]?
│  └─ SQLiteSearch subclass + sqlite_search hook
│     → Spelling correction, recency boost, custom scoring
│
└─ Awesomebar customization?
   └─ Client-side: override build_options or use search dialog

Link Field Search

Configuring search_fields (Most Common Need)

# In DocType JSON or via customize form
{
    "search_fields": "customer_name, customer_group",
    "title_field": "customer_name",
    "show_title_field_in_link": 1
}

ALWAYS set

search_fields

name

CUST-001

How Link Search Works

1. User types in link field → calls

   search_link(doctype, txt)

2. Searches across:

   name

   +

   title_field

   +

   search_fields

3. Allowed field types: Data, Text, Small Text, Long Text, Link, Select, Autocomplete, Read Only, Text Editor
4. Prefix matches rank higher than substring matches
5. Respects

   fields automatically

Custom Link Query

# hooks.py — override search for a specific DocType
standard_queries = {
    "Customer": "my_app.queries.customer_query"
}

# my_app/queries.py — MUST be @frappe.whitelist()
@frappe.whitelist()
def customer_query(doctype, txt, searchfield, start, page_length, filters,
                   as_dict=False, reference_doctype=None,
                   ignore_user_permissions=False):
    # Return list of dicts: [{"value": name, "description": label}, ...]
    return frappe.db.sql("""
        SELECT name, customer_name as description
        FROM `tabCustomer`
        WHERE (name LIKE %(txt)s OR customer_name LIKE %(txt)s)
        AND status = 'Active'
        ORDER BY customer_name
        LIMIT %(start)s, %(page_length)s
    """, {"txt": f"%{txt}%", "start": start, "page_length": page_length},
    as_dict=True)

Per-Field Query Override

// In Client Script or Form JS
frappe.ui.form.on("Sales Order", {
    setup(frm) {
        frm.set_query("customer", () => ({
            filters: { status: "Active", territory: frm.doc.territory }
        }));
    }
});

Global Search

Enabling

Set

in_global_search = 1

How It Works

• Indexed fields stored in

  __global_search

  table
• Synced via Redis queue every 15 minutes
• Uses DB-native fulltext: MariaDB

  MATCH...AGAINST

  , PostgreSQL

  TSVECTOR

• Permission-filtered results

Rebuilding Index

# Rebuild for specific DocType
from frappe.utils.global_search import rebuild_for_doctype
rebuild_for_doctype("Sales Order")

# Rebuild everything
from frappe.utils.global_search import rebuild
rebuild()

hooks.py Configuration

# Default doctypes for global search
global_search_doctypes = {
    "Default": [
        {"doctype": "Contact"},
        {"doctype": "Customer"},
        {"doctype": "Sales Order"},
    ]
}

SQLiteSearch [v15+]

Creating Custom Search

# my_app/search.py
from frappe.search.sqlite_search import SQLiteSearch

class ProjectSearch(SQLiteSearch):
    INDEX_SCHEMA = {
        "metadata_fields": ["project", "owner", "status"],
        "tokenizer": "unicode61 remove_diacritics 2 tokenchars '-_'",
    }

    INDEXABLE_DOCTYPES = {
        "Task": {
            "fields": ["name", {"title": "subject"}, {"content": "description"},
                       "modified", "project"],
            "filters": {"status": ("!=", "Cancelled")}
        },
        "Project": {
            "fields": ["name", {"title": "project_name"}, {"content": "notes"},
                       "modified", "status"],
        }
    }

    def get_search_filters(self, query, scope=None):
        """Permission filtering — return additional WHERE conditions"""
        return {}

Register in hooks.py

sqlite_search = ['my_app.search.ProjectSearch']

Features (automatic)

• Spelling correction: Trigram-based fuzzy matching
• Recency boosting: 1.8x (24h) → 1.5x (7d) → 1.2x (30d) → 1.1x (90d)
• Resumable indexing: Progress tracked, atomic replacement
• Auto-scheduling: Build every 3h, queue every 5min, doc events trigger updates
