Why?

-----



Indonesia is the fourth most populous country in the world. Indonesian internet users use indonesian language as their primary language. So, developers need a tool to improve text searching in Indonesian language. One of the most important tool is a stemmer.



Stemming is the process of reducing morphological variants of a word to a common stem form. Some researches has shown that stemming is language-dependent.



Problems with common search approach

-------------------------------------



Let's say we have a blog content:



    Rakyat memenuhi halaman gedung untuk menyuarakan isi hatinya.



The query below will result none.



```sql

SELECT * FROM posts WHERE content LIKE '%suara%'

```



Even fuzzy full-text-search tool needs a stemmer to improve the result. A possible improvement would be to index the reduced version of the sentence as follow:



    rakyat penuh halaman gedung suara isi hati



We would also reduce the search keyword:



    Bersuara => suara



Our Goals

----------



- Have a high quality PHP library to ease stemming Indonesian words.

- Integrate well with other packages / frameworks.

- Have a simple and easy to use API
