To use the Lucene full text search, you first need to rename the file FullTextLucene.java.txt to FullTestLucene.java and compile it. Also, you need the Lucene library in the classpath.
To initialize, call:
</p>
<pre>
CREATE ALIAS IF NOT EXISTS FTL_INIT FOR "org.h2.fulltext.FullTextLucene.init";
CALL FTL_INIT();
</pre>
<p>
Afterwards, you can create a full text index for a table using:
</p>
<pre>
CREATE TABLE TEST(ID INT PRIMARY KEY, NAME VARCHAR);
INSERT INTO TEST VALUES(1, 'Hello World');
CALL FTL_CREATE_INDEX('PUBLIC', 'TEST', NULL);
</pre>
<p>
PUBLIC is the schema, TEST is the table name. The list of column names (column separated) is optional,
in this case all columns are indexed. The index is updated in read time. To search the index, use the following query:
</p>
<pre>
SELECT * FROM FTL_SEARCH('Hello', 0, 0);
</pre>
<p>
You can also call the index from within a Java application:
H2 supports Lucene full text search and native full text search implementation.
Using the Native Full Text Search
To initialize, call:
CREATE ALIAS IF NOT EXISTS FT_INIT FOR "org.h2.fulltext.FullText.init";
CALL FT_INIT();
Afterwards, you can create a full text index for a table using:
CREATE TABLE TEST(ID INT PRIMARY KEY, NAME VARCHAR);
INSERT INTO TEST VALUES(1, 'Hello World');
CALL FT_CREATE_INDEX('PUBLIC', 'TEST', NULL);
where PUBLIC is the schema, TEST is the table name. The list of column names (column separated) is optional, in this case all columns are indexed. The index is updated in read time. To search the index, use the following query:
SELECT * FROM FT_SEARCH('Hello', 0, 0);
