normalize-for-search

About

Un-accents and un-umlauts characters in a string. Also preliminary converts the string to lower case. We use it for autocomplete: both for the matched strings -- on the server side, when indexing; and for the strings the user types into a text input in the browser.

Has nothing to do with Unicode Normalization, but rather expects the passed strings being already Unicode-normalized.

Installation

Under Node.js

$ npm install --save normalize-for-search

then

var normalizeForSearch = require('normalize-for-search');

In CouchDB

Just drop the src/normalize.js contents into your CouchDB design document -- for example, into {views: {lib: {normalize: 'JSON-ENCODED src/normalize.js CODE HERE'}}}, and then require it elsewhere:

var normalizeForSearch = require('views/lib/normalize');

In the browser, with AngularJS

$ bower install --save normalize-for-search

then

<script src="/components/normalize-for-search/src/normalize.js"></script>

<script>
    var injector = angular.injector(['normalizeForSearch']);
    injector.invoke(function (normalizeForSearchFilter) { ... });
</script>

<p>{{ text | normalizeForSearch }}</p>

Thus, the Angular module normalizeForSearch declares a filter function available both in the HTML partials, and in the controllers' code.

API

normalizeForSearch('Dät ist naïve und ÜBERCOOL, ё-маё!');
// Results in 'dat ist naive und ubercool, е-мае!'
