When suggestion is enabled all results will be filled up (until limit, default 1000) with similar matches ordered by relevance.

|
||||
Actually phonetic suggestions are not supported, for that purpose use the encoder and tokenizer which provides similar functionality. Suggestions comes into game when a query has multiple words/phrases. Assume a query contains 3 words. When the index just match 2 of 3 words then normally you will get no results, but with suggestion enabled you will also get results when 2 of 3 words was matched as well 1 of 3 words was matched (depends on the limit), also sorted by relevance.

|

> Set the tokenizer at least to "reverse" or "full" when using RTL.
|
||||
|
||||
Just set the field "rtl" to _true_ and use a compatible tokenizer:
|
||||
|
||||
```js
|
||||
var index = FlexSearch.create({
|
||||
encode: "icase",
|
||||
tokenize: "reverse",
|
||||
rtl: true
|
||||
});
|
||||
```
|
||||
|
||||
<a name="cjk"></a>
|
||||
### CJK Word Break (Chinese, Japanese, Korean)
|
||||
|
||||
Set a custom tokenizer which fits your needs, e.g.:
|
||||
|
||||
```js
|
||||
var index = FlexSearch.create({
|
||||
encode: false,
|
||||
tokenize: function(str){
|
||||
return str.split(/[\x00-\x7F]+/);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
You can also pass a custom encoder function to apply some linguistic transformations.
|
||||
|
||||
```js
|
||||
index.add(0, "서울시가 잠이 든 시간에 아무 말, 미뤄, 미뤄");
|
||||
```
|
||||
|
||||
```js
|
||||
var results = index.search("든");
|
||||
```
|

```js
|
||||
var results = index.search("시간에");
