Not possible to use in web worker

[mslourens]

It is not possible to run pouchdb-quick-search in a web worker, because at the end of the script this line of code is executed:

if (typeof window !== 'undefined' && window.PouchDB) {
  window.PouchDB.plugin(exports);
}

In a web worker process window is not defined, so the plugin is never added to PouchDb. I would suggest you use the way the pouchdb-find plugin is added:

if (typeof PouchDB !== 'undefined') {
  PouchDB.plugin(exports);
}
