Overview

Domains

Hawksearch has three environments available: Development, Test and a load-balanced Production. When using the search API methods in this document, the following domains can be used to access each environment after your engine has been set-up in that environment.

🚧

Before You Begin

Please ensure that your client-specific endpoints are configured before implementing any API integrations. Please refer to this article to learn more about client-specific endpoints and reach out to our CSD team for any questions.

Development

client-specific URL: https://enginename.dev.index-na.hawksearch.com

Configurations for an engine in this location are maintained in the HawkSearch Workbench at dev.hawksearch.net.

Test

client-specific URL: https://enginename.test.index-na.hawksearch.com

Configurations for an engine in this location are maintained in the HawkSearch Workbench at test.hawksearch.net.

Production

client-specific URL: https://enginename.index-na.hawksearch.com

Configurations for an engine in this location are maintained in the Hawksearch Workbench at dashboard-na.hawksearch.com.

Hierarchy API Methods

Upsert

The Upsert method is used to insert hierarchy records. The hierarchy records are often categories or departments. There is a limit of 125 hierarchy objects that can be sent in a request. This method can be called multiple times to accommodate more than 125. After all hierarchy objects have been sent, the hierarchy/rebuild method can be used.

Hierarchy API Examples

Following operations are provided by Hawksearch hierarchy API:

• Upsert to add new or update existing hierarchies
• RebuildMapping to initiate hierarchy mapping
• DeleteHierarchyItems to remove a specific list of hierarchies
• DeleteAllHierarchyItems to remove all hierarchies

General Notes:

1. Ensure that the header contains the Hawksearch Key for all the operations:
   Request headers must contain the Hawksearch API Key as follows:
   Format: X-HawkSearch-ApiKey : {your engine API key}
   Example: X-HawkSearch-ApiKey : 12345678-9ABC-DEF0-1234-56789ABCDEF0
2. Hierarchy addition is a 3-step process with hierarchy upsert, hierarchy rebuild and index items operations.

A. Following steps are required to successfully add hierarchies to the engine

Some highly important notes to know before you add the hierarchies

1. If you intend to perform a full hierarchy update, please delete the existing hierarchies as mentioned in the section C below before inserting new hierarchies.
2. The name of the topmost hierarchy must be lower case and have no spaces or special symbols except for underscores. All other Hierarchy names under this do not have any naming restrictions. Usually, the topmost hierarchy name (without spaces) is category. The field name in the below example is category so there needs to be a field created by this name in the dashboard, other hierarchies do not need fields.
3. The difference in naming is that the names of other hierarchies are common names example Outdoor Kitchens or As Seen On TV, but the name of the topmost hierarchy must be the fieldname example products, category, department_name etc - please see Field Configuration: Naming Convention
4. The parent hierarchy id for the topmost hierarchy must be 0
5. The field created for category must be marked as hierarchical on the dashboard:
   
6. A facet must be created for this field which is either a nested checkbox or nested list:
   

Step 1: Upsert the hierarchies in a POST request

Upsert hierarchy API

{  
    "IndexName": "demo.20200101.123456",  
    "Hierarchies": [  
        {  
            "HierarchyId": "1234",  
            "Name": "category",  
            "ParentHierarchyId": "0",  
            "IsActive": true,  
            "SortOrder": 0,  
            "Custom": ""  
        },  
        {  
            "HierarchyId": "1111",  
            "Name": "Clothing",  
            "ParentHierarchyId": "1234",  
            "IsActive": true,  
            "SortOrder": 0,  
            "Custom": ""  
        },  
        {  
            "HierarchyId": "2222",  
            "Name": "Accessories",  
            "ParentHierarchyId": "1234",  
            "IsActive": true,  
            "SortOrder": 1,  
            "Custom": ""  
        },  
        {  
            "HierarchyId": "3333",  
            "Name": "Footwear",  
            "ParentHierarchyId": "1234",  
            "IsActive": true,  
            "SortOrder": 1,  
            "Custom": ""  
        },  
        {  
            "HierarchyId": "1212",  
            "Name": "Jackets",  
            "ParentHierarchyId": "1111",  
            "IsActive": true,  
            "SortOrder": 1,  
            "Custom": ""  
        },  
        {  
            "HierarchyId": "3434",  
            "Name": "Shirts",  
            "ParentHierarchyId": "1111",  
            "IsActive": true,  
            "SortOrder": 1,  
            "Custom": ""  
        }  
    ]  
}

Step 2: Map and configure the hierarchies added in step1

Rebuild index hierarchy

{  
	"IndexName": "demo.20200101.123456"  
}

B. Below API request lists the hierarchies

{  
	"IndexName": "demo.20200101.123456"  
}

C. Following are the options to remove hierarchies from the engine:

(Please rebuild hierarchy before and after deleting hierarchies)

Option 1: Delete certain hierarchies

Note that deleting a parent hierarchy will delete all other hierarchies under it

Delete items from hierarchy API

{  
	"IndexName": "demo.20200101.123456",  
	"Ids" : [  
		"1234","5678","1212","3434"  
	]  
}

Option 2: Delete all hierarchies

Delete all hierarchy items API

{  
	"IndexName": "demo.20200101.123456"  
}

D. Associate Items with one or more hierarchies

Since the hierarchies and the actual data items are indexed separately, we need to associate the items with the hierarchies. This can be established through normal indexing API.

📘

Note

1. The index-items request must contain the hierarchy ids as the value of the topmost category and must not be the name.
2. The hierarchies need to be split into multiple requests if they exceed the limit of 125 hierarchies in a request, splitting will not be necessary for hierarchies within this limit.
3. Please upsert the hierarchies, rebuild the hierarchies and then index all the items to ensure a seamless indexing activity.

If we have Clothing (1111) → Accessories (2222) → Jackets (1212) as one of the hierarchies, then the index-items request will be as follows:
The facet created out of the category field will be hierarchical

{  
"IndexName": "demo.20200101.123456",  
"Items":  
    \[  
        {  
            "name": [  
                "Demo item1"  
            ],  
            "id": [  
                "Test001"  
            ],  
            "brand": [  
                "Test brand item"  
            ],  
            "category": [  
                "1111","2222","1212"  
            ]  
        }  
    ]  
}
