Examples

Save a rule

C#

Rule ruleToSave = new Rule
{
    ObjectID = "a-rule-id",
    Enabled = false,
    Conditions = new List<Condition>
    {
      new Condition { Anchoring = "contains", Pattern = "smartphone" },
    },
    Consequence = new Consequence
    {
        Params = new ConsequenceParams
        {
            AutomaticFacetFilters = new List<AutomaticFacetFilter>
            {
                new AutomaticFacetFilter { Facet = "category = 1" }
            }
        }
    },
    Validity = new List<TimeRange>
    {
        new TimeRange
        {
            From = new DateTimeOffset(DateTime.UtcNow).ToUnixTimeSeconds(),
            Until = new DateTimeOffset(DateTime.UtcNow.AddDays(10)).ToUnixTimeSeconds()
        }
    }
  };

index.SaveRule(rule, forwardToReplicas: false);

// Asynchronous
await index.SaveRuleAsync(rule, forwardToReplicas: false);

Save a rule with alternatives enabled

C#

Rule ruleToSave = new Rule
{
    ObjectID = "a-rule-id",
    Conditions = new List<Condition>
    {
      new Condition { Anchoring = "contains", Pattern = "smartphone", Alternatives = true },
    }
    Consequence = new Consequence
    {
        Params = new ConsequenceParams
        {
            Filters = "category = 1"
        }
    },
  };
index.SaveRule(rule);

Save a rule with a context-based condition

C#

Rule ruleToSave = new Rule
{
    ObjectID = "a-rule-id",
    Conditions = new List<Condition>
    {
      new Condition { Context = "mobile"  }
    },
    Consequence = new Consequence
    {
        Params = new ConsequenceParams
        {
            AutomaticFacetFilters = new List<AutomaticFacetFilter>
            {
                new AutomaticFacetFilter { Facet = "release_date >= 1568498400" }
            }
        }
    }
  };

index.SaveRule(rule, forwardToReplicas: false);

Parameters

rule · object · required

The rule object with conditions and consequences. For a complete JSON rule object, see the saveRule HTTP API reference.

Show child attributes

consequence · object · required

Action to perform when this rule is triggered. For more information, see Consquences.

Show child attributes

filterPromotes · boolean · default: false

Determines whether promoted records must also match active filters for the consequence to apply.

This ensures user-applied filters take priority and irrelevant matches aren’t shown. For example, if you promote a record with color: red but the user filters for color: blue, the “red” record won’t be shown.

hide · object[]

List of objects with objectID properties for records you want to hide.

Example:

JSON

{
  "consequence": {
    "hide": [
      {
        "objectID": "test-record-123"
      }
    ]
  }
}

promote · object[]

Fix positions of records in the search results. You can promote up to 300 records per rule.

Show child attributes

objectID · string

Object ID of the record to promote. Either objectID or objectIDs is required.

objectIDs · string

Object IDs of a group of records to promote. A group can have up to 100 records. Either objectID or objectIDs is required.

The records are placed as a group at position. For example, if you want to promote four records to position 0, they will be the first four search results.

position · integer · required

Position in the search results where you want to show the promoted records, starting with 0.

params · object

Parameters to apply to this search. You can use all search parameters, plus the special fields query, automaticFacetFilters, and automaticOptionalFacetFilters.

Show child attributes

automaticFacetFilters · string[] | object[]

Facet filters to apply to this search. You can use this to respond to search queries that match a facet value. For example, if users search for “comedy”, which matches a facet value of the “genre” facet, you can filter the results to show the top-ranked comedy movies.

Show child attributes

facet · string · required

Facet name. It must match the placeholder used in the patterns parameter of the rule’s condition. For example, with pattern: {facet:genre}, automaticFacetFilters.facet must be genre.

disjunctive · boolean · default: false

Whether multiple matching filter conditions should be combined with OR. By default, multiple matching filter conditions are combined with AND.

score · integer · default: 1

Filter scores to give different weights to individual filters.

automaticOptionalFacetFilters · string[] | object[]

Optional filters to apply to this search. This is the same as automaticFacetFilters, but with optionalFilters: records that don’t match the filters will be ranked below matching records.

query · string | object

If query is a string, it replaces the entire search query. If query is an object, it describes the incremental edits made to the query.

Show child attributes

remove · string[]

Words to delete from the query.

edits · object[]

Changes to make to the query.

• Remove words or patterns from the query: (Example: remove “red” from the query)

  JSON

  {
    "query": {
      "edits": [
        {
          "type": "remove",
          "delete": "red"
        }
      ]
    }
  }
  

• Replace words or patterns in the query: (Example: replace “red” with “blue”)

  JSON

  {
    "query": {
      "edits": [
        {
          "type": "replace",
          "delete": "red",
          "insert": "blue"
        }
      ]
    }
  }
  

userData · object

A JSON object with custom data that will be appended to the userData array in the search response. This object isn’t interpreted by the API and is limited to 1 kB of minified JSON.

objectID · string · required

Unique identifier of the rule object.

conditions · object[]

List of conditions that should trigger this rule. You can add up to 25 conditions per rule.

Show child attributes

alternatives · boolean · default: false

Whether the pattern should match plurals, synonyms, and typos. For example, if pattern is shoe, and alternatives is true, the rule is also triggered when the query is shoes, or sheo (typo).

For each word in pattern, Algolia checks up to 10 alternatives.

If the total number of alternatives is more than 10, Algolia may not check some or even any of the words.

anchoring · enum<string>

Which part of the query pattern must match to trigger the rule:

• contains: the pattern can match anywhere in the query
• is: the pattern must exactly match the query
• endsWith: the pattern must match the end of the query
• startsWith: the pattern must match the beginning of the query

Empty queries are only allowed with is.

context · string

An additional restriction that only triggers the rule, when the search has the same value as ruleContexts parameter. For example, if context: "mobile", the rule is only triggered when the search request has a matching ruleContexts: "mobile". A rule context must only contain alphanumeric characters.

filters · string

Filters that trigger the rule.

You can add filters using the syntax facet:value so that the rule is triggered, when the specific filter is selected. You can use filters on its own or combine it with the pattern parameter. You can’t combine multiple filters with OR and you can’t use numeric filters.

pattern · string

Query pattern that triggers the rule.

You can use either a literal string, or a special pattern {facet:ATTRIBUTE}, where ATTRIBUTE is a facet name. The rule is triggered if the query matches the literal string or a value of the specified facet. For example, with pattern: {facet:genre}, the rule is triggered when users search for a genre, such as “comedy”.

When specifying a query pattern, you must also specify an anchoring.

description · string

Descriptive text, that helps you find the rule when searching and understand its purpose.

enabled · boolean · default: true

Whether the rule is active. If false, the rule is still added to the index but it’s not applied when searching.

validity · object[]

Time ranges when this rule should be active. By default, a rule is always active.

Show child attributes

from · integer

Timestamp when the rule should become active, in seconds since the Unix epoch.

to · integer

Timestamp when the rule should become inactive again, in seconds since the Unix epoch.

forwardToReplicas · boolean · default: false

Whether to add or update the rule for all replicas of the index.

Response

taskID · integer

The task ID used with the waitTask method.

updatedAt · string

Date at which the indexing job has been created.

Response as JSON

This section shows the JSON response returned by the API. Each API client wraps this response in language-specific objects, so the structure may vary. To view the response, use the getLogs method. Don’t rely on the order of properties—JSON objects don’t preserve key order.
