OpenSearch is an open web standard for describing search functions of web services. If a website supports it, the browser will take note and offer the user to install the website as a search machine.
One especially nice aspect of it is, that OpenSearch can be implemented in just a few lines of code. It was thus easy to bring to both the frontend of museum-digital and musdb, to make searching objects right from the browser’s search bar possible, just as you can quickly search Wikipedia or Amazon on many browsers by default.
Since musdb does not feature a simple, unqualified search function (one always needs to specify, whether one searches for a tag, place, etc.), OpenSearch offers using the full text search on musdb.
