What is Yandex Search Engine?

Yandex Search Engine is a powerful tool developed by Yandex, a major Russian tech company. It utilizes artificial intelligence to enhance search results, providing users with relevant and accurate information quickly. It competes closely with other search engines like Google and includes many unique features tailored for its audience.

How Yandex Search Engine Works

The Yandex Search Engine uses complex algorithms to index web pages and improve search relevancy. It applies natural language processing and machine learning to understand user queries better, enhancing the quality of search results. Users receive personalized content based on their search history and preferences, making the search experience more intuitive.

πŸ” Yandex Search Engine: Core Formulas and Ranking Principles

Yandex Search Engine is a complex system that combines classic information retrieval models with advanced machine learning and natural language processing. Below are key formulas and concepts used in ranking and indexing.

1. Term Frequency (TF)

TF measures how often a term appears in a document:

TF(t, d) = count(t in d) / total_terms_in_d

2. Inverse Document Frequency (IDF)

IDF measures how rare a term is across all documents:

IDF(t) = log(N / df_t)

Where N is the total number of documents, and df_t is the number of documents containing term t.

3. TF-IDF Score

Classic relevance scoring function:

TFIDF(t, d) = TF(t, d) * IDF(t)

4. BM25 Ranking Function

Used in Yandex for baseline scoring:


BM25(t, d) = IDF(t) * ((TF(t, d) * (k + 1)) / 
(TF(t, d) + k * (1 - b + b * (|d| / avg_dlen)))

Where k and b are tunable parameters, |d| is document length, and avg_dlen is the average document length.

5. MatrixNet Scoring (Yandex Machine Learning)

MatrixNet is a proprietary gradient-boosting algorithm used for ranking:

Score(q, d) = MatrixNet(features(q, d))

Where features(q, d) are engineered metrics such as click data, user behavior, and content relevance.

6. Final Ranking Formula

Yandex combines multiple signals into a weighted ranking score:

FinalScore = Ξ± * BM25 + Ξ² * BehavioralScore + Ξ³ * MatrixNetScore

Where Ξ±, Ξ², and Ξ³ are model weights learned from user feedback and historical data.

πŸ”Ž Yandex Search Engine: Practical Examples

Example 1: Calculating TF-IDF for Query Matching

Query: weather forecast

Document contains term weather 3 times in 100 words:

TF(weather, d) = 3 / 100 = 0.03

If df_weather = 1000 and total docs N = 1,000,000:

IDF(weather) = log(1,000,000 / 1000) = log(1000) β‰ˆ 6.9

TF-IDF Score:

TFIDF = 0.03 * 6.9 β‰ˆ 0.207

Example 2: BM25 Scoring for Ranking

Given:


TF = 4, |d| = 200, avg_dlen = 250
k = 1.5, b = 0.75
IDF = 3.2

BM25 calculation:


BM25 = 3.2 * ((4 * 2.5) / (4 + 1.5 * (1 - 0.75 + 0.75 * (200 / 250))))
     = 3.2 * (10 / (4 + 1.5 * (1 - 0.75 + 0.6)))
     = 3.2 * (10 / (4 + 1.5 * 0.85))
     β‰ˆ 3.2 * (10 / 5.275) β‰ˆ 3.2 * 1.895 β‰ˆ 6.06

Example 3: MatrixNet Final Ranking Score

Features:


BM25 = 5.4
BehavioralScore = 0.8
MatrixNetScore = 0.92
Weights: Ξ± = 0.4, Ξ² = 0.3, Ξ³ = 0.3

Final score calculation:


FinalScore = 0.4 * 5.4 + 0.3 * 0.8 + 0.3 * 0.92
            = 2.16 + 0.24 + 0.276 = 2.676

This score is used to rank the document for the user’s query.
