# pg_bigm

pg_bigm 中文支持 比 pg_trgm 要好，pg_trgm 在 Mac osx 中不支持中文等 Unicode 字符，原因如下：

The pg_bigm module provides full text search capability in [PostgreSQL](https://www.postgresql.org/).

This module allows a user to create **2-gram** (bigram) index for faster full text search.

pg_bigm is released under the [PostgreSQL License](https://opensource.org/licenses/postgresql), a liberal Open Source license, similar to the BSD or MIT licenses.

For more information look at [the official pg_bigm web site](https://pgbigm.osdn.jp/index_en.html).
