+Handling languages was completely replaced by a more generic approach. All language-specific definitions has excluded and was optimized for maximum dead-code elimination when using compiler/bundler. Each language exists of 5 definitions, which are divided into two groups:
 
-1. Charset (mandatory)
-    1. `encode`
-    2. `split`
-    3. `rtl`
-2. Language (optional)
-    1. `stemmer`
-    2. `filter`
-    3. `matcher`
-

+    3. ___filter___, type: `string[]`
+
+The charset contains the encoding logic, the language contains stemmer, stopword filter and matchers. Multiple language definitions can use the same charset encoder. Also this separation let you manage different language definitions for special use cases (e.g. names, cities, dialects/slang, etc.).

-#### About Tokenizer
-
-In FlexSearch you can't provide your own tokenizer, because it is a direct dependency to the core unit. What in FlexSearch is called "split" is often named the "tokenizer" on other libraries. Of course splitting sentences into words is also a kind of tokenize, but the tokenizer of FlexSearch splits the word itself into chunks (strict, forward, reverse/both, full, ngram).
-
 ### 1. Language Packs: ES6 Modules
 
-The goal is to collect language definitions and providing them as built-ins for simple reusing. The folder `/lang/` includes all definitions, also divided by charset and language. Let's take an example on how to make a full qualified initialization of a built-in language:
+The most simple way to assign charset/language specific encoding via modules is:
 
 ```js
-import { encode, split, rtl } from "./dist/module/lang/latin/index.js";
+import charset from "./dist/module/lang/latin/soundex.js";
+import lang from "./dist/module/lang/en.js";
+
+const index = FlexSearch({
+    charset: charset,
+    lang: lang
+});
+```
+
+Just import the __default export__ by each module and assign them accordingly.
+
+The full qualified example from above is:
+
+```js
+import { encode, rtl, tokenize } from "./dist/module/lang/latin/soundex.js";
 import { stemmer, filter, matcher } from "./dist/module/lang/en.js";
 
 const index = FlexSearch({
-    // charset:
     encode: encode,
-    split: split,
+    // assign forced tokenizer first:
+    tokenize: tokenize || "forward",
     rtl: rtl,
-    // language:
-    filter: filter,
     stemmer: stemmer,
-    matcher: matcher
+    matcher: matcher,
+    filter: filter
 });
 ```
 
 The example above is the standard interface which is at least exported from each charset/language.
 
-When passing nothing to the initializer:
-
-```js
-const index = FlexSearch();
-```
-
-it uses the default `latin` schema by default, pretty much the same like:
-
-```js
-import { encode, split } from "./dist/module/lang/latin/index.js";
-
-const index = FlexSearch({
-    encode: encode,
-    split: split
-});
-```
+__Note:__ Some of the encoder variants limit the use of built-in tokenizer (e.g. soundex). To be save prioritize the forced tokenizer and fall back to your choice, e.g. `tokenize || "forward"`.
 
 #### Encoder Variants
 
-You remember the old encoding variants like `simple`, `advanced`, `extra`, or `balanced`? These are also supported and provides you several variants of encoding (which has different performance and results).
+You remember the encoding variants like `simple`, `advanced`, `extra`, or `balanced`? These are also supported and provides you several variants of encoding (which differs in performance and degree of normalization).
 
 It is pretty straight forward when using a encoder variant:

+import advanced from "./dist/module/lang/latin/advanced.js";
+import { encode } from "./dist/module/lang/latin/extra.js";
 
 const index_advanced = FlexSearch({
-    encode: advanced,
-    split: split
+    // inherit all definitions:
+    charset: advanced
 });
 
 const index_extra = FlexSearch({
-    encode: extra,
-    split: split
+    // just inherit the encoder:
+    encode: encode
 });
 ```
 
+#### Available Latin Encoders
+
+1. default
+2. simple
+3. advanced
+4. extra
+5. balance
+6. soundex
+
+You can assign a charset by passing the charset during initialization, e.g. `charset: "latin"` for the default charset encoder or `charset: "latin:soundex"` for a encoder variant.
+
 #### Dialect / Slang
 
 Language definitions (especially matchers) also could be used to normalize dialect and slang of a specific language.
 
 ### 2. Language Packs: ES5 Modules
 
+You need to make the charset and/or language definitions available:
+
+1. All charset definitions are included in the `flexsearch.min.js` build by default, but no language-specific definitions are included
+2. You can load packages located in `/dist/lang/` (files refers to languages, folders are charsets)
+3. You can make a custom build

-    // language:

-    stemmer: "en",
-    matcher: "en"
-});
-```

-```js
-var index = FlexSearch({
-    charset: "latin",
+const index = FlexSearch({
+    charset: "latin:soundex",
     lang: "en"
 });
 ```
 
+> Use the `charset:variant` notation to assign charset and its variants. When just passing the charset without a variant will automatically resolve as `charset:default`.
+
+The example above is a shortcut for:

+```js

+    encode: "latin:soundex",

+});

+
+```js
+const index = FlexSearch({
+    charset: "latin",
+    lang: "en",
+    matcher: {}
+});
+```

+### Partial Tokenizer
+
+In FlexSearch you can't provide your own partial tokenizer, because it is a direct dependency to the core unit. The built-in tokenizer of FlexSearch splits each word into chunks by different patterns:

+2. forward

 ### Language Processing Pipeline
 
 This is the default pipeline provided by FlexSearch:

 </p>
 
-You can specify your own pipeline or extend it in the upcoming release.
+#### Custom Pipeline
+
+At first take a look into the default pipeline in `src/common.js`. It is very simple and straight forward. The pipeline will process as some sort of inversion of control, the final encoder implementation has to handle charset and also language specific transformations. This workaround has left over from many tests.
+
+Inject the default pipeline by e.g.:
+
+```js
+this.pipeline(
+
+    /* string: */ str.toLowerCase(),
+    /* normalize: */ false,
+    /* split: */ split,
+    /* collapse: */ false
+);
+```
+
+Use the pipeline schema from above to understand the iteration and the difference of pre-encoding and post-encoding. Stemmer and matchers needs to be applied after charset normalization but before language transformations, filters also.
+
+Here is a good example of extending pipelines: `src/lang/latin/extra.js` → `src/lang/latin/advanced.js` → `src/lang/latin/simple.js`.
