The effect is both delightful and enticing, making the game play feel like a hunt through the wild of whatever city you’re playing in.” – David Attenborough’s ‘Pokémon Go’ Narration Is So Soothing
  • “Vacations are times to kick back and relax, but getaways can also be a source of friction among families, friends or couples, as back-seat driving or paying restaurant bills cause tempers to fray. Here are a few tips from Sonia Prades, a psychologist specializing in family relationships, on how to ensure a stress-free summer break.” – Stress-free summer: How to vacation with friends
  • “…stress can really do a number on your body. Too much of it can cause headaches, stomachaches, muscle tension, and fatigue, according to the Mayo Clinic. It can also increase anxiety, and totally ruin your mood. So yes — it’s totally worth taking the time to increase your moments of relaxation throughout the day.” – 11 Ways To Find Moments Of Relaxation In Your Day
  • “I’m not sure what impresses me the most in this video of workers painting the street. Is it the perfect angles drawn free hand with a tool that’s essentially a stick with an open box at the end? Is it the dude dropping the hot thermoplastic into that box, while his partner is drawing the letters? Or is it the exquisite, ballerina-like footwork of the two workers who make sure not to step on the letters they just made?” – Watching Workers Paint Letters on a Street Is So Soothing
  • “Although stereotype threat is not unique to women, we have singled it out as a primary cause of women’s greater workplace stress for a simple reason: the workplace is a minefield of negative stereotypes for women. This minefield exists because success in business and the professions — being perceived as a leader, effective negotiator, strong advocate, and keen evaluator — involves performing tasks associated with positive male stereotypes and negative female ones.” – Why Women Feel More Stress at Work

Feature: Mango Query

This is the fourth in a series of blog posts introducing the Apache CouchDB 2.0 release. Read parts one, two, and three in the series. 

Two years ago, Cloudant developed a declarative style syntax for creating and querying Cloudant indexes. The idea was to attract users who were not familiar with Map-Reduce and Javascript but still wanted to experience the power of NOSQL databases. Moreover, the syntax was MongoDB-inspired, meaning that users already familiar with MongoDB’s find() operator could easily transition over to Cloudant’s new declarative API. Cloudant introduced this feature as Cloudant Query. Within a few months, Cloudant donated Cloudant Query to CouchDB. We decided to adopt the development codename for introduction to the CouchDB community. Lo and behold: Mango.

For a quick introduction on how to get started with creating and querying indexes using Mango, check out this informative post: Introducing Cloudant Query.

When Mango was first donated to CouchDB, the codebases were identical. However, the repositories diverged as Cloudant added a new text-search feature to Cloudant Query that leveraged Cloudant’s existing full-text-search API. The new text-search feature also made the existing query API more flexible and truly ad-hoc. At the time, Cloudant’s full-text-search was not open sourced, and thus CouchDB’s version could not reap the benefits.

In late July of 2015, Cloudant open sourced full-text-search. This allowed Cloudant Query and Mango Query to become synchronized.

Check out Enable Full Text Search in Apache CouchDB to start using text search with Mango Query.

To fully understand the differences between original Mango JSON indexes and text indexes checkout Mango JSON vs Text Indexes. One of the restrictions of Mango in the past two years was that users had to create an index first before running a query. This was a nuisance to developers who just wanted to execute a query against the database, especially when they encountered the infamous no_index_found error. We’re happy to announce that in CouchDB 2.0, this restriction has been lifted. Users can now execute queries without the need to create an index first.

You can download the latest release candidate from http://couchdb.apache.org/release-candidate/2.0/. Files with -RC in their name a special release candidate tags, and the files with the git hash in their name are builds off of every commit to CouchDB master.

We are inviting the community to thoroughly test their applications with CouchDB 2.0 release candidates. See the testing and setup instructions for more details.
