Re: DataImportHandler
I faced the same problem before, but that's because some parent classloader has loaded the DataImport class instead of using the SolrResourceLoader's delegated classloader. How are you starting your Solr? Via Eclipse? If you try starting Solr using cmdline, will you encounter the same issue?

Re: highlighting in multiValued field
Hi All, I'll share my own workaround for my own issue. I simply created a new multiValued field that concatenantes the multiValued fields for index. During search, I will then have both fields in the same array position. Thanks, Jeff On Fri, May 27, 2011 at 10:24 PM, Jeffrey Chang jclal...@gmail.com wrote: Hi Bob, Hmm...

highlighting in multiValued field
Hi All, I am having a problem with search highlighting for multiValued fields and am wondering if someone can point me in the right direction. I have in my schema a multiValued field as such: field name=description type=text stored=true indexed=true multiValued=true/ When I search for term Tel, it returns me the correct doc: doc ... arr name=description strTel to talent 1/str strTel to talent 2/str /arr ... /doc When I enable highlighting, it returns me the following highlight with only one vector returned: ... lst name=highlighting lst name=1 arr name=description stremTel/em to talent 1/str /arr /lst /lst What I'm expecting is actually both vectors to be returned as such: lst name=highlighting lst name=1 arr name=description stremTel/em to talent 1/str stremTel/em to talent 2/str /arr /lst /lst Am I doing something wrong in my config or query (I'm using default)? Any help is appreciated. Thanks, Jeff

Re: Solr without Server / Search solutions with Solr on DVD (examples?)

Re: FW: DIH relating multiple DataSources
I'll reply the solution to this thread on my own (with a different email
address).
Did some debugging on 1.4.1 source code, my issue is in the data-config.xml
file, the field column name when stored in Map object uses the DBs column
casing (e.g. ID -- id):
entity name=parentEntity ...
field column=ID name=XXX /
...
entity childEntity ... query=select * from jctest where
ID='${parentEntity.ID}'
...
The config above does not work because the parentEntity.ID, the ID token
when compared in the Map object is stored as 'id'. If I change
parentEntity.ID to parentEntity.id (lower case id) then it works.
Perhaps the class *VariableResolverImpl *should consider a case insensitive
Map get?
Thanks,
Jeff

Subject: DIH relating multiple DataSources
Hi All,
I'm a newbie to SOLR and is hoping to get some help.
I was able to get DIH to work with one datasource. What I'm trying to
achieve is using two datasources to build my document. Below is my
data-config:
dataConfig
dataSource name=localDB driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/ebook user=ebook password=masked
batchSize=1 /
dataSource name=remoteDB driver=com.mysql.jdbc.Driver
url=jdbc:mysql://tw-stntlab1:3306/test user=root password=masked
batchSize=1 /
document name=epub
entity dataSource=localDB rootEntity=true name=epub
pk=ID query=select * from epub
field column=ID name=id /
field column=Name name=url /
field column=Author name=content /
entity dataSource=remoteDB name=test
query=select TESTCOLUMN from jctest where ID='${epub.ID}'
field column=TESTCOLUMN name=title /
/entity
/entity
/document
/dataConfig
If the above possible? I can't seem to get my title field above populated
from a second datasource but the fields identified in my rootEntity using
the first datasource works perfectly fine.
Thanks,
Jeff

Re: Cant retrieve data
I'm also new but I was able to get DIH working. From your response your have: ... Indexing completed. Added/Updated: 0 documents. Deleted 0 documents. ... str name=Total Documents Processed0/str I believe your fetch (db source and query) is correct based on the response but perhaps your mapping isn't. I would check required fields on your schema.xml and see if they are properly mapped.
