Search without the Internet. New beta Yandex application. Yandex mobile application - a universal assistant for iOS and Android The best Yandex applications

Mobile applications produced by Yandex are tools for optimizing the user's life. You won't find games, entertaining puzzles or photo filters here. Yandex applications are designed to: simplify tasks, monitor expenses, make quick purchases, order cheap tickets, etc. Below we suggest looking at the most useful software that will be useful to everyone.

1. Yandex.Taxi

This is an application for quickly ordering a budget taxi to anywhere in your city. The main advantage of this software is that the user can compare the cost of moving from one point to another. Thanks to this application, you do not need to call the operator, check prices, change banknotes and worry about the timely delivery of the car. To order a car in Yandex.Taxi, you need to fill out a small application

• car delivery address;
• passenger delivery address;
• time (you can specify “in 10 minutes” and the car will arrive shortly);
• mobile phone;
• tariff (there are “Economy” and “Business”).

2. Yandex.Health

This is a healthcare consultant application. Of course, the software will not replace an examination with a doctor, and the user will in any case have to visit the hospital to clarify the diagnosis.

The application was created for those who want to find out details about their disease, reviews of prescribed medications, or get advice from a doctor online.

Yandex.Health features:

• consultations with doctors of various specializations;
• complete confidentiality;
• 24/7 assistance;
• communication with a doctor via chat or video call.

Consultations are absolutely free. Here you can ask any question you are interested in and receive a detailed answer from a professional. The topic can be anything: wound treatment, pregnancy, infections, flu in a child, etc.

3. Yandex.Metro

The application contains metro maps of Moscow, St. Petersburg, Kyiv, Minsk and Istanbul. With Yandex.Metro, you no longer need to ask passers-by about the location of a particular station, the fare and the exact names of the lines.

Just install the application on your smartphone and use it every time you visit the above capitals. Here you will find information about the metro (opening hours, ticket prices, etc.), schedule, numbering of stops and much more. With Yandex.Metro you won't get lost in the big city!

4. Yandex.Fines

The application will be useful for both car owners and those who do not have a car. The interface is very concise: it displays only what the user needs to know. Yandex.Fines displays:

• the amount to be paid;
• the period for which you are required to pay the fine;
• an extract from the legislation under which you were fined.

Install this application even if you don’t have a car (pedestrians get fined too!). You can pay directly through software by clicking on the corresponding icon under the amount. All that is required from the user is to enter the details from which the money will be withdrawn (bank card or electronic wallet).

5. Yandex.Conversation

Very the right application, which can come in handy at any time. This is software that makes it easier to communicate with blind and hard of hearing people. The application reacts to voice and turns what is written into text, and vice versa - it speaks out what was typed. The only rule: words must be pronounced clearly and legibly so that the system does not confuse them with similar root and similar combinations.

Many of us still find ourselves in situations where we need to quickly find important information, but internet access is limited or non-existent. It’s one thing to try to open an entertaining post on a website, and quite another to look for a phone number hotline bank or hospital. Today, for the first time, I will tell Habr readers about how the acceleration of search in the Yandex application has led to the ability to search for important information without the Internet.

But first, you need to understand the main thing: why did we even undertake offline search if the sites from the search results are still inaccessible in the absence of a network?

EDGE search

Yandex's radar traditionally shows people who enter a query, but then leave the page without waiting for it to load due to poor mobile internet. In this situation, we could not influence the overall quality of the network and the loading speed of all sites, but it was worth trying to make at least the search process less painful and save some time. Actually, that’s why this project was originally called EDGE search, i.e. search on slow internet.

There are two ways to speed up your search. First, optimize the web version and the APIs that the application uses as much as possible. And this work is also being done, but even this is not enough. Secondly, you can pre-load onto your device something that will be useful in case of a poor connection. Obviously, it is physically impossible to fit the entire Internet index into a phone. Therefore, it was necessary to go from the local storage of ready-made search results for specific queries. According to what? No one yet knows how to predict a person’s future needs with high accuracy (but we are learning). Therefore, we take popular recurring queries.

When we talk about popular queries, many people imagine a [VKontakte] query and several similar ones. In fact, we have hundreds of thousands of less obvious requests that are regularly repeated in large quantities. And this is already many hundreds of megabytes of results. Moreover, we planned to save not only the search results, but also the hints that appear during the process of entering a query. And here many will ask: why store hints offline, since a person is quite capable of entering a query without them?

When entering queries in the Yandex application, users see unusual search tips, but in the form of individual words/pairs of words (i.e. predictive text input). Regular hints cannot be edited: if you need to add a word, you will have to enter the entire query yourself. Hints in the form of words allow you to make edits, cover a much larger number of queries and significantly speed up their entry by a person.

But the main thing is that the tips turned out to be especially useful when working offline. These hints help people phrase their question in a way that most people do, which in turn increases the chance that the answer will be retrieved from the local cache. That is why it was important to save the tips.

Empirically, we have selected a certain minimum search queries(about 150 thousand) and hints, less than which there was no point in keeping. But the volume of all this luggage was still beyond decent (several hundred megabytes). Even taking into account the fact that only the top 10 results were stored for each query. Something had to be done.

From optimization to offline

We started looking for everything that could be sent “under the knife.” Each result contained not only links to sites, but also favicons and snippets. Favicons are pictures, which means serious savings could be achieved here. The same site can appear in the results for completely different queries, so we initially did not duplicate favicons, but stored them by site. And then we made it so that the probability of saving the favicon is directly proportional to the frequency of the site appearing in search results. In other words, we abandoned most of the favicons, but visually this is not very noticeable.

The more we reduced organic search results in favor of ready-made answers, the closer we came to understanding that our EDGE search was no longer just speeding up the work, but was capable of answering a wide range of questions without an Internet connection at all. Without noticing it, we were already working on offline search. This means that you have to rely on ready-made answers. Having realized this, we began to enrich the database with important facts that previously could not get there due to limited popularity of the request. These results contain only answers, without listing sites.

Using a similar scheme, we copied into the database all the object response cards and all requests for which the object response is available. Offline search cards differ from the originals in the almost complete absence of pictures: we removed them for reasons of economy.

The growth of the fact base required further work over the optimization of such a data storage structure that would be careful about device resources.

Dictionaries

The database is not downloaded to the device as a whole, but in the form of separate dictionaries, and only with a Wi-Fi connection and only with a sufficient charge level. The division into dictionaries was made for two reasons. Firstly, if the connection breaks during downloading, then during the next attempt only those dictionaries will be downloaded that were not downloaded earlier. Secondly, to further save space, the database is downloaded and stored on the device in a compressed form, but with each request it is not unpacked entirely, but only in the necessary parts.

Each dictionary contains queries starting with certain letters, as well as all the data for search results and hints for these queries. It turned out to be more logical to sort the data before dividing it into dictionaries by the first letters of queries than, for example, by their popularity. Imagine the situation: the first dictionary contains the most popular queries, the second contains slightly less popular ones, and so on. But the popularity of queries often changes, and this will lead to the need to regularly update dictionaries just to move a query from one to another. This costs traffic, energy and time. Therefore, it was important to ensure that when updating the database, queries did not move between dictionaries. Alphabetical order turned out to be a simple and effective solution.

Answers to the same queries may vary in different parts of the country, so different dictionaries are formed for different regions. Moreover, during short-term visits to another region, the application will not rush to update dictionaries - we have provided scenarios for business trips and tourism.

No matter how hard we try, offline search does not cover all possible queries, but it already helps out on average with every third one. As with any average result, this means that some users encounter offline responses much more often than others. Therefore, we, of course, allow you to completely disable offline search in the settings.

Our team would be interested to know the opinion of Habr readers about this direction and to receive feedback on the work of the beta
