Example
DatabaseDataStore
This section describes Database crawling.
This example uses MySQL. There is the following table in testdb, and you can access data with username=foo and password=bar.
CREATE TABLE doc (
id BIGINT NOT NULL AUTO_INCREMENT,
title VARCHAR(100) NOT NULL,
content VARCHAR(255) NOT NULL,
latitude VARCHAR(20),
longitude VARCHAR(20),
versionNo INTEGER NOT NULL,
PRIMARY KEY (id)
);
Insert the following data.
INSERT INTO doc (title, content, latitude, longitude, versionNo) VALUES ('Title 1', 'This is Content 1.', '37.77493', ' -122.419416', 1);
INSERT INTO doc (title, content, latitude, longitude, versionNo) VALUES ('Title 2', 'This is Content 2.', '34.701909', '135.494977', 1);
INSERT INTO doc (title, content, latitude, longitude, versionNo) VALUES ('Title 3', 'This is Content 3.', '-33.868901', '151.207091', 1);
INSERT INTO doc (title, content, latitude, longitude, versionNo) VALUES ('Title 4', 'This is Content 4.', '51.500152', '-0.13.636', 1);
INSERT INTO doc (title, content, latitude, longitude, versionNo) VALUES ('Title 5', 'This is Content 5.', '35.6813.6', '139.766084', 1);
Parameter
Set parameters of crawling config as below.
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/testdb?useUnicode=true&characterEncoding=UTF-8
username=foo
password=bar
sql=select * from doc
The value of parameters is key/value format. The description is below.
| driver | JDBC driver class |
| url | URL |
| username | Username to access to DB |
| password | Password to access to DB |
| sql | SQL statement to crawl data |
Table: Parameter for DB
Script
Set script values of crawling config as below.
url="http://localhost/" + id
host="localhost"
site="localhost"
title=title
content=content
digest=content
anchor=
content_length=content.length()
last_modified=new java.util.Date()
location=latitude + "," + longitude
latitude=latitude
longitude=longitude
The format is key/value. For specified values, Groovy language is available. The description for Script is below.
| url | URL(Displayed link in search result page) |
| host | Host name |
| site | Site path |
| title | Title |
| content | Content |
| cache | Content Cache(Not search target) |
| digest | Displayed description in search result page |
| anchor | Links contained in this document(optional) |
| content_length | Content length |
| last_modified | Last modified for this document |
Table: Configuaration for Script
JDBC Driver
To crawl data in database, you need JDBC driver and put Jar file into app/WEB-INF/lib directory. In this example, copy mysql-connector-java-5.1.39.jar to app/WEB-INF/lib.
CsvDataStore
CsvDataStore is to import data from CSV files.
For example, create test.csv in /home/john/csv, and the content is below.
1,Title 1,This is Test1.
2,Title 2,This is Test2.
3,Title 3,This is Test3.
4,Title 4,This is Test4.
5,Title 5,This is Test5.
6,Title 6,This is Test6.
7,Title 7,This is Test7.
8,Title 8,This is Test8.
9,Title 9,This is Test9.
Parameter
Set parameters of crawling config as below.
directories=/home/john/csv
fileEncoding=UTF-8
The value of parameters is key/value format. For the description, see below.
| directories | Directories which contains csv file(.csv or .tsv) |
| files | CSV files (if you want to specify them) |
| fileEncoding | Encofing of CSV files |
| separatorCharacter | Separator character in CSV content |
Table: Parameters for CSV file
Script
Set script values of crawling config as below.
url="http://localhost/" + cell1
host="localhost"
site="localhost"
title=cell2
content=cell3
cache=cell3
digest=cell3
anchor=
content_length=cell3.length()
last_modified=new java.util.Date()
The format is key/value. For keys, they are the same as database crawling. You can use values in CSV file as cell[number] (cell1 is a first cell). If cell does not exist, it returns null.
CsvListDataStore
You can use CsvListDataStore to crawl a large number of target files, and also reduce the crawling time to use CSV file which contains only updated file paths.
The file format is as below.
[Action]<Separator character>[Path]
Specify one of the following value for Action.
create：Created file modify：Updated file delete：Deleted file
For Path, you can sepecify a path in the same notation as a setting for file crawling.
For example, create test.csv in /home/john/csv, and the content is below.
modify,smb://servername/data/testfile1.txt
modify,smb://servername/data/testfile2.txt
modify,smb://servername/data/testfile3.txt
modify,smb://servername/data/testfile4.txt
modify,smb://servername/data/testfile5.txt
modify,smb://servername/data/testfile6.txt
modify,smb://servername/data/testfile7.txt
modify,smb://servername/data/testfile8.txt
modify,smb://servername/data/testfile9.txt
modify,smb://servername/data/testfile10.txt
Parameter
Set parameters of crawling config as below.
directories=/home/taro/csv
fileEncoding=Shift_JIS
The value of parameters is key/value format. For the description, see below.
| directories | Directories which contains csv file(.csv or .tsv) |
| fileEncoding | Encofing of CSV files |
| separatorCharacter | Separator character in CSV content |
Table: Parameter for CsvListDataStore
Script
Set script values of crawling config as below.
event_type=cell1
url=cell2
The format is key/value. For keys, they are the same as database crawling.
If authentication is required at the crawling destination, you must also add the following settings.
crawler.file.auth=example
crawler.file.auth.example.scheme=SAMBA
crawler.file.auth.example.username=username
crawler.file.auth.example.password=password
