https://www.toptal.com/android/android-customization-how-to-build-a-ui-component-that-does-what-you-want
It is not uncommon for developers to find themselves in need of a UI component that is either not provided by the platform they are targeting or is, indeed, provided, but lacks a certain property or behavior. The answer to both scenarios is a custom UI component. The Android UI model is inherently customizable, offering the means to create custom UI components in various ways.
Needle in a Haystack: A Nifty Large-Scale Text Search Algorithm Tutorial (Publication)
https://www.toptal.com/algorithms/needle-in-a-haystack-a-nifty-large-scale-text-search-algorithm
When coming across the term "text search", one usually thinks of a large body of text, which is indexed in a way that makes it possible to quickly look up one or more search terms when they are entered by a user. This is a classic problem in computer science, to which many solutions exist. But how about a reverse scenario? What if what's available for indexing beforehand is a group of search phrases, and only at runtime is a large body of text presented for searching?
