How to approach Solr schema for the first time - node.js

Question

I am trying to understand what is the best way to design my Solr Schema. and if there is a possibility to do it in a less complex way using solrJ.
I am currently working with solr's example server so i can understand how solr works.
if i understood correctly so far, the way to define the following schema:
Book= { title: String,
year: Int }
Author = { name: String,
books: [book] } <-- list/array of book objects
is to use CopyFields:
<fields>
<field name="name" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="books" type="string" indexed="true" stored="false" multiValued="false"/>
<!-- books will contain: -->
<field name="title" type="string" indexed="true" stored="true" multiValued="true"/>
<field name="year" type="int" indexed="true" stored="true"/>
</fields>
<copyField source="title" dest="books"/>
<copyField source="year" dest="books"/>
was i correct?
if so, how do i upload a new author to my database?
i tried to upload form my node.js server using solr-client:
function ADDONE(){
var docs = [];
//generate 4 docs.
for(var i = 0; i <= 4 ; i++){
var doc = {
id : 20 + i ,
name : "Author"+i ,
books: [{title: "firstBook" , year: 1900+i} ,
{title: "SecondBook" , year: 1901+i} ]
}
docs.push(doc);
}
// Add documents to Solr
client.add(docs,function(err,obj){
if(err){
console.log(err);
}else{
console.log(obj);
}
});
}
ADDONE();
But this won't work. what is the correct way to define each document? am i even close?
the example i gave was written for node.js solr-client, but i prefer to use Java and it's solr Client (solrJ?).
I would also like to know how a contract a query for books form the years 1900 to 1910.
Thanks.

Answer 1

you can also use the dynamics fields
<fields>
<field name="name" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="books" type="string" indexed="true" stored="false" multiValued="false"/>
<dynamicField name="books_year_*" type="string" indexed="true" stored="true" multiValued="false"/>
<dynamicField name="books_title_*" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="book_title" type="string" indexed="true" stored="true" multiValued="true"/>
<copyField source="books_title_*" dest="book_title"/>
<field name="book_year" type="string" indexed="true" stored="true" multiValued="true"/>
<copyField source="books_year_*" dest="book_year"/>
</fields>
and with your method,
books: [{title: "firstBook" , year: 1900+i} =>
"books_title_"+i : firstBook
"books_year_"+i : 1900+i
Query:
select?q=book_year:"1970"

solr does not allow for structured objects.
If you want to do this, you must define entities.
For example, passing with Data Import Request Handler
http://wiki.apache.org/solr/DataImportHandler#Full_Import_Example
So you can have one entity for book and one entity for author
