Solr arrays not getting inserted in to solr

Hi I’m running mongo-connector latest build and I’m unable to insert list values into solr multiValued fields. In my test index, I have the followling solr fields.

<field name="_id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
   <field name="_ts" type="long" indexed="true" stored="true" multiValued="false" />
   <field name="_ns" type="string" indexed="true" stored="true" multiValued="false" />
   <field name="spec_name" type = "string" indexed = "true" stored = "true" multiValued="true"/>
   <field name="spec_value" type = "string" indexed = "true" stored = "true" multiValued="true"/>

Given these two documents from my mongodb

{ "_id" : ObjectId("5320d76ebdca98e379b97b9b"), "jobID" : "2597402", "spec_value" : "20" }
{ "_id" : ObjectId("5320d7ccbdca98e379b97b9c"), "jobID" : "2597402", "spec_name" : [  "one",  "two" ], "spec_value" : [  "20",  "test" ] }

the first document inserts the spec_value field correctly, but the second does not.

Is this possibly a bug?

Also, here is my mongo-connector call for starting it up.

mongo-connector -m localhost:27017 -t http://localhost:8181/solr/content  -d mongo-connector/mongo_connector/doc_managers/solr_doc_manager.py -n test.test -a tomcat -p tomcat -i spec_name,spec_value,jobID

Thanks for any help you may offer, Tim

@acmeinternetsolutions , Mongo Connector unwinds arrays, so

{ "_id" : ObjectId("5320d7ccbdca98e379b97b9c"), 
  "jobID" : "2597402", 
  "spec_name" : [  "one",  "two" ], 
  "spec_value" : [  "20",  "test" ] }

will be turned into the following before insertion into Solr:

{ "_id" : ObjectId("5320d7ccbdca98e379b97b9c"), 
  "jobID" : "2597402", 
  "spec_name.0" : "one", 
  "spec_name.1": "two", 
  "spec_value.0" : "20", 
  "spec_value.1": "test" }

This is necessary if there is a sub-document inside of an array. Solr has no notion of “sub-documents” like MongoDB does, and so these need to be flattened, and in order to do this, arrays must also be unwound. For a lengthier discussion about this, you can refer to #89. You might be able to get around this with the copyField directive in your schema.xml.

I see this post is closed. However, I would like to know if there is any way to handle an array of String within an array of Object.

Ex:

{ “name”: “doc1”, “a” : [ { “b” : “something.0”, “c” : [ “1001”, “1002” ] },{ “b” : “something.1”, “c” : [ “1006”, “1007” ] } ] }, { “name”: “doc2”, “a” : [ { “b” : “something.2”, “c” : [ “1001”, “1002” ] },{ “b” : “something 3”, “c” : [ “1006”, “1007” ] } ] }

This get converted as { “name” : “doc1”, a.0.b = “something.0”, a.0.c.0 = “1001”, a.0.c.1 = “1002” a.1.b=“something.1”, a.1.c.0 = “1006”, a.1.c.1 = “1007” }, { “name” : “doc2”, a.0.b = “something.2”, a.0.c.0 = “1001”, a.0.c.1 = “1002”, a.1.b=“something.3”, a.1.c.0 = “1006”, a.1.c.1 = “1007” }

Now how can I search in Solr to match all documents that has a..b=“something.0” and a..c contains “1002”

Sorry for the lengthy detail.
