The search giant Google could be the very first place people visit to search for things and answers on the web. While it has a massive data to about practically anything on the web, search engines like Google's Search don't go well for programming languages queries. Google is trying to fix that.
Google is improving its Search by giving it the ability to understand queries containing sequences of 2-3 special characters, such as [== vs ===] and [+=].
What this means, Google Search should at least show more relevant answers about technical search queries than before, as it will return results on the meaning of these sequences in programming languages.
Google explained this in its blog post on March 2nd, 2017, saying that:
As the internet grows and the web expanding, Google has secured its place as one of the most prominent search engines. Google has been more than capable to fetch answers from the usual alphanumeric queries. But it may find difficulties to relate results from queries that include syntax and special characters.
With the improvement, the search giant has become better in seeking for information about various programming languages. Users that use Google to learn the basics of computer science, for example, can include Google as one of their resources.
Google stated that it's going to continue to improve the experience over time. Just like Google said, "we're techies, too!"
