PGroonga is a PostgreSQL extension that makes PostgreSQL fast full text search platform for all languages! It's released under PostgreSQL license.
There are some PostgreSQL extensions that improves full text search feature of PostgreSQL such as pg_trgm^1.
pg_trgm doesn't support languages that use non-alphanumerics characters such as Japanese and Chinese.
PGroonga supports all languages, provides rich full text search related features and is very fast. Because PGroonga uses Groonga^2 that is a full-fledged full text search engine as backend.
See the following benchmark results for performance:
PGroonga also supports JSON search. You can use each value for condition. You can also perform full text search against all texts in JSON like textsearch in PostgreSQL.
Here are changes in PGroonga 3.0.0:
query_allow_column=true index option in
You can use PGroonga without full text search knowledge. You just create an index and puts a condition into WHERE:
CREATE INDEX index_name ON table USING pgroonga (column);
SELECT * FROM table WHERE column &@~ 'PostgreSQL';
You can also use LIKE to use PGroonga. PGroonga provides a feature that performs LIKE with index. LIKE with PGroonga index is faster than LIKE without index. It means that you can improve performance without changing your application that uses the following SQL:
SELECT * FROM table WHERE column LIKE '%PostgreSQL%';
You can install PGroonga easily. Because PGroonga provides packages for major platforms. There are binaries for Windows.
