 Hi,

 I am using Solr with DIH and started getting errors when the database
 time/date fields are getting imported in to Solr. I have used the date as
 the field type but when i looked up at the docs it looks like the date
 field does not accept (Thu, 06 Sep 2012 22:32:33 +) or (1346976590)
 formats.

 Also, When i used field_type as 'text_ar' and indexed a line with arabic
 text, Solr is displaying some non-ISO characters. It looks like the text is
 not being unicoded.

 Did anyone face a similar issue ? The Solr date field type does not support
 a variety of formats.

 Is there any work around to solve this kind of issues ?

 Many Thanks,

Debugging DIH

[Hasan Diwan]

I have some data in an H2 database that I'd like to move to SOLR. I
probably should/could extract and post the contents as 1 new document per
record, but I'd like to configure the data import handler and am having
some difficulty doing so. Following the wiki instructions[1], I have the
following in my db-data-config.xml:
dataConfig
dataSource type=JdbcDataSource driver=org.h2.Driver
url=jdbc:h2:tcp://192.168.1.6/finance user=sa /
document
  entity name=receipt query=select location as location, amount as
amount, done_on as when from RECEIPTS as r join APP_USERS as a on r.user_id
= a.id/
/document
/dataConfig

I also have dropped the JDBC driver into db/lib, witness:
% jar tvf ./lib/h2-1.3.164.jar | grep 'Driver'
13 Fri Feb 03 12:02:56 PST 2012 META-INF/services/java.sql.Driver
  2508 Fri Feb 03 12:02:56 PST 2012 org/h2/Driver.class
   485 Fri Feb 03 12:02:56 PST 2012 org/h2/util/DbDriverActivator.class

and I've added the appropriate fields to schema.xml:
  field name=location type=string indexed=true stored=true/
   field name=amount type=currency indexed=true stored=true/
   field name=when type=date indexed=true stored=true/

There's nothing in my index and 343 rows in my table. What is going on? -- H

 Two easy ones:
 1) Facets on a text field are simple word counts by document.
 2) If you want the number of times a word appears inside a document,
 that requires a separate dataset called a 'term vector'. This is a
 list of all words in a document with a count for each one.
 These are simple queries. There are also batch computations where you
 create a 'term-document matrix', with a row for each document and a
 column for all terms that appear in any document. These computations
 require exporting all of your data into a separate computation.

  I'd like to put an arbitrary set of text into Solr and then have Solr
 tell

 put
  in 100 paragraphs of text about sports, I would like to retrieve topics
  like swimming, basketball, tennis if the three most popular and
 discussed
  topics are those inside the text.
 
  Is Solr the correct tool to do something like this?  Or, is this too
  unstructured to get this kind of result without manually categorizing it?
 
  Is the correct term for this faceting?  It seems to me that faceting
  requires putting the data into a more structured format (for example,
  telling the index that this is the manufacturer, etc.)
 
  Basically, I would like to get something like a tag cloud (relevant
 topics
  with weights for each term) without asking users to tag things manually.

JDBC import yields no data

trying to use the JDBC importer[1]. My configuration is given below:
dataConfig
  dataSource driver=net.sf.log4jdbc.DriverSpy user=sa

  deltaQuery=SELECT 'transaction' as type, name, currency, amount,
done_on from receipts join app_users on user_id = app_users.id where
done_on  '${dataimporter.last_index_time}'
field column=NAME name=name /

field column=transaction_time name=done_on / !-- resolve

 Expert:
 The Merge Scheduler in Lucene controls how merges are performed.  The
ConcurrentMergeScheduler (Lucene 2.3 default)
  can perform merges in the background using separate threads.  The
SerialMergeScheduler (Lucene 2.2 default) does not.

  As long as Solr is the only process modifying your index, it is
  safe to use Lucene's in process locking mechanism.  But you may
  specify one of the other Lucene LockFactory implementations in
  the event that you have a custom situation.

  none = NoLockFactory (typically only used with read only indexes)
  single = SingleInstanceLockFactory (suggested)
  native = NativeFSLockFactory
  simple = SimpleFSLockFactory

  ('simple' is the default for backwards compatibility with Solr 1.2)

 This defeats the locking mechanism that allows multiple
 processes to safely access a lucene index, and should be
 used with care.
 This is not needed if lock type is 'none' or 'single'
