Search operators are special words, symbols, and phrases included in the search query that help you specify the requested information in order to produce the most accurate result. Their main task is to filter out queries with specific content, narrow down the data, and exclude unnecessary information. You can combine operators with each other to make your search even more productive.

For example, let's take the word "key", which has several meanings, so to get the result that we need, we will refine the query: key +treble, key +spring, key +spanner. As a result, you get sites that have the full set of words from the query.

How do search engines work?
There are three main stages in the operation of search engines:
- Scanning. A search robot or spider is responsible for the first stage. It collects and selects information from sites, analyzes changes in content, URLs, as well as code and site maps. All this is done in order to determine the type of information displayed.
- Indexing. As soon as the scan is completed, the indexer organizes and performs a quick search for the collected information, i.e. analyzes the site data.
- Search engine. At the last stage, sites are sorted according to the query preferences, quality, and degree of compliance. This way, we see the content on the search results page.
