Install Solr
download and install Solr from http://lucene.apache.org/solr/.
you can access Solr admin from your browser: http://localhost:8983/solr/
use the port number used in installation.
MySQL connector
Download JDBC driver for MySQL from http://dev.mysql.com/downloads/connector/j/.
Copy file from the downloaded archive 'mysql-connector-java-*.jar' to the folder 'contrib/dataimporthandler/lib' in the folder where Solr was installed. Create 'lib' folder if needed.
MS SQL Server connector
Download Microsoft JDBC Driver 4.0 for SQL Server from: http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774
copy file 'sqljdbc4.jar' to 'contrib/dataimporthandler/lib'
Setup a new collection
create a new folder for a new collection - 'myproducts'. The collection will be located in '/solr/myproducts' folder. Create folders conf and data in the collection folder:
- /solr/myproducts/conf
- /solr/myproducts/data
solrconfig.xml
copy solrconfig.xml from an existing collection. Find my version of solrconfig.xml below in this gist.
edit solrconfig.xml by adding:
<lib dir="../../contrib/dataimporthandler/lib" regex=".*\.jar" />
<lib dir="../../dist/" regex="solr-dataimporthandler-.*\.jar" />
Make sure that 'dist' folder contains two files for data import handler:
- solr-dataimporthandler-4.10.2.jar
- solr-dataimporthandler-extras-4.10.2.jar
add these lines to solrconfig.xml:
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
data-config.xml for MySQL database
the file 'data-config.xml' will define data we want to import/index from our datasource. Assuming that our DB named mydb1 and we have table products with columns id, name and updated_at. Column 'updated_at' of datetime type stores the date of last modification of the row. This column will be used in incremental import to track rows modified since the last import into Solr.
# define data source
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/mydb1"
user="root"
password=""/>
<document>
<entity name="product"
pk="id"
query="select id,name from products"
deltaImportQuery="SELECT id,name from products WHERE id='${dih.delta.id}'"
deltaQuery="SELECT id FROM products WHERE updated_at > '${dih.last_index_time}'"
>
<field column="id" name="id"/>
<field column="name" name="name"/>
</entity>
</document>
</dataConfig>
- The 'query' gives the data needed to populate fields of the Solr document in full-import
- The 'deltaImportQuery' gives the data needed to populate fields when running a delta-import
- The 'deltaQuery' gives the primary keys of the current entity which have changes since the last index time
Full-import command uses the "query" query, delta-import command uses the delta components.
data-config.xml for SQL Server database
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://servername\instancename;databaseName=mydb"
user="sa"
password="mypass"/>
<document>
<entity name="product"
pk="id"
query="select id,name from products"
deltaImportQuery="SELECT id,name from products WHERE id='${dih.delta.id}'"
deltaQuery="SELECT id FROM products WHERE updated_at > '${dih.last_index_time}'"
>
<field column="id" name="id"/>
<field column="name" name="name"/>
</entity>
</document>
</dataConfig>
schema.xml
edit file 'schema.xml' accordingly to fields defined in data-import.xml:
<schema name="example" version="1.5">
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="name" type="text_general" indexed="true" stored="true"/>
...
add collection to solr
use admin interface in your browser to add a new collection. Add core:
- name: myproducts
- instanceDir: myproducts
Perform full or incremental import
After successfully adding a collection to Solr you can select it and run dataimport commands:
- full-import - use URL: http://localhost:8983/solr/myproducts/dataimport?command=full-import
- delta-import - use URL: http://localhost:8983/solr/myproducts/dataimport?command=delta-import
The full import loads all data every time, while incremental import means only adding the data that changed since the last indexing. By default, full import starts with removal the existing index (parameter clean=true).
Note! Use clean=false while running delta-import command.
debug=true - The debug mode limits the number of rows to 10 by default and it also forces indexing to be synchronous with the request.

<!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer)
Kuromoji has a search mode (default) that does segmentation useful for search. A heuristic
is used to segment compounds into its parts and the compound itself is kept as synonym.
Valid values for attribute mode are:
normal: regular segmentation
search: segmentation useful for search with synonyms compounds (default)
extended: same as search mode, but unigrams unknown words (experimental)
For some applications it might be good to use search mode for indexing and normal mode for
queries to reduce recall and prevent parts of compounds from being matched and highlighted.
Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.
Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
model with your own entries for segmentation, part-of-speech tags and readings without a need
to specify weights. Notice that user dictionaries have not been subject to extensive testing.
User dictionary attributes are:
userDictionary: user dictionary filename
userDictionaryEncoding: user dictionary encoding (default is UTF-8)
See lang/userdict_ja.txt for a sample user dictionary file.
Punctuation characters are discarded by default. Use discardPunctuation="false" to keep them.
See http://wiki.apache.org/solr/JapaneseLanguageSupport for more on Japanese language support.

fitting into the URL. addHttpRequestToContext - if set to true, it will instruct
the requestParsers to include the original HttpServletRequest

key "httpRequest". It will not be used by any of the existing

<searchComponent name="highlight" class="solr.HighlightComponent" />
