Entity Search

Introduction

This guide focuses on how to utilize the Entity Search endpoint. Entity Search is a powerful tool for discovering entities or records of interest within the Sayari Knowledge Graph, primarily designed for lead-generation activities.

For entity matching at scale, we recommend utilizing the Resolution Matching endpoint.

Getting Started

1

Basic Search Structure

Entity Search supports both GET and POST methods. Both examples below are equivalent:

1GET /v1/search/entity?q=Apple
2
3POST /v1/search/entity
4{
5  "q": "Apple"
6}

The request will search against all available fields: name, address, identifier, business_purpose, and contact information.

GET requests require URL encoding of all search arguments (e.g., foo OR (bar~5) becomes foo%20OR%20(bar~5)).

2

Field-Specific Search

Narrow your search to specific fields for more targeted results:

1{
2  "q": "Apple",
3  "fields": ["name"]
4}
3

Apply Filters

Further refine your results using filters:

1{
2  "q": "Apple",
3  "fields": ["name"],
4  "filter": {
5    "entity_type": ["company"],
6    "country": ["USA"]
7  }
8}
4

Include Facets

Add facets to analyze your filtered results by country, source, and entity type:

1{
2  "q": "Apple",
3  "fields": ["name"],
4  "filter": {
5    "entity_type": ["company"],
6    "country": ["USA"]
7  },
8  "facets": true
9}
5

Submit the Query

1curl -X POST "https://api.sayari.com/v1/search/entity" \
2     -H "Authorization: Bearer <token>" \
3     -H "Content-Type: application/json" \
4     -d '{
5  "q": "apple",
6  "fields": ["name"],
7  "filter": {
8    "entity_type": ["company"],
9    "country": ["USA"]
10  },
11  "advanced": false,
12  "facets": true
13}'

Key Concepts

Corporate Extensions

Global company corporate extension terms that appear in names such as: Inc, LLC, private company, or s.a.g.r are treated as stop words / noise, and do not factor into matching logic.

Response Ranking

Entity Search prioritizes connections; entities with a higher degree (number of relationships) will be sorted to the top.

1{
2   "data": [
3       {
4           "id": "WS1zKrBef9JXaSL3BTk6Eg",
5           "label": "Apple Incorporated",
6           "degree": 81
7       }
8   ]
9}

Result Explainability

Sayari entities are resolved via multiple sources, resulting in arrays of attributes. The matches segment helps you understand which terms matched against the entity’s attributes.

1{
2  "matches": {
3    "name": [
4      "<em>Apple</em> Inc",
5      "<em>Apple</em> Incorporated"
6    ],
7    "address": [
8      "ONE APPLE PARK WAY, <em>Cupertino</em>, CA, 95014"
9    ]
10  }
11}
