I created multivalued field in schema.xml:
<field name="path" type="pint" multiValued="true" indexed="true" stored="true"/>
I created my own search component class like this:
public class CustomComponent extends SearchComponent {
private static final Logger LOG = LoggerFactory.getLogger(CustomComponent.class);
#Override
public void prepare(ResponseBuilder rb) throws IOException {
}
#Override
public void process(ResponseBuilder rb) throws IOException {
LOG.info("CustomComponent running ---");
SolrParams params = rb.req.getParams();
CoreContainer coreContainer = rb.req.getCore().getCoreContainer();
SolrCore solrCore = coreContainer.getCore("example_core");
SolrIndexSearcher categorySearcher = solrCore.getSearcher().get();
IndexReader categoryReader = categorySearcher.getIndexReader();
String pathId = params.get("pathId"); //3
FieldType path = solrCore.getLatestSchema().getField("path").getType();
StandardQueryParser standardQueryParser = new StandardQueryParser();
standardQueryParser.setAnalyzer(path.getQueryAnalyzer());
Query q = standardQueryParser.parse(pathId, "path");
DocList docList = searcher.getDocList(q, null, null, 0, 1000, 1000);
LOG.info(docListsize()); // returns 0
//even if there is a document which has field with such value
}
}
What is wrong here? Is there a way to search on multivalued field? Thanks for answer in advance.
Whenever I try to query Solr using a Spring data repository I get the following exception:

Document:
public class Product {
#Id

#Field
private String description;
#Field
private String title;
// getter/setter
}
Repository:
public interface ProductRepository extends SolrCrudRepository<Product, String> {
List<Product> findByTitleStartingWith(String title);
}
Configuration + Test:
#ComponentScan
#EnableSolrRepositories("foo.bar.repository")
public class Application {
#Bean
public SolrServer solrServer() {
return new HttpSolrServer("http://localhost:8983/solr");
}
#Bean
public SolrTemplate solrTemplate(SolrServer server) throws Exception {
return new SolrTemplate(server);
}
public static void main(String[] args) {
ApplicationContext context = new AnnotationConfigApplicationContext(Application.class);
ProductRepository repository = context.getBean(ProductRepository.class);
Product product = new Product();
product.setTitle("Foo title");
product.setDescription("Bar description");
product.setId(UUID.randomUUID().toString());
repository.save(product);
List<Product> list = repository.findByTitleStartingWith("Foo"); // <-- error
System.out.println("result: " + list);
}
}
I Found the solution myself:
I was using the default field configuration for Solr (schema.xml). This configuration includes the fields title and description by default:
<field name="title" type="text_general" indexed="true" stored="true" multiValued="true"/>
<field name="description" type="text_general" indexed="true" stored="true"/>
By default title is a multiValued field. This caused an error when Spring data tried to map the fields back to my Product class.
Removing multiValued="true" (or setting it to false) from the title field solved the problem.
I have the below bean class for defining my solrInputDocument
public class VenueDocumentSolr extends SolrInputDocument {
#Field
private int id;
#Field
private String uid;
...
}
And I try to get the results using the below code:
SolrQuery query = new SolrQuery();
query.setQuery(SearchForRestaurants);
QueryResponse rsp = SolrUtil.issueSolrQuery(query);
for (SolrDocument s : rsp.getResults())
System.out.println(s);
List<VenueDocumentSolr> beans = rsp.getBeans(VenueDocumentSolr.class);
the above code works sometimes and throws the below Exception rest of the time.
I cross checked and added missing fields to my bean class. But of no use. I still get the error :(

beanlist = binder.getBeans(PortalBean.class, list);
} catch (SolrServerException | IOException e) {
// TODO Auto-generated catch block

}
return beanlist;
}
}
The bean is mapped as :

}
#Field("currencies")
public void setCurrencies(String [] currencies) {

}
}
Also please note that managed-schema file need to have proper definition of the fields:
example as per my use case:
<field name="branding" type="string"/>
<field name="currencies" type="strings"/>
<field name="description" type="string"/>
<field name="how_to_url" type="string"/>
<field name="id" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
<field name="image" type="string"/>
<field name="name" type="string"/>
<field name="rating" type="tdouble"/>
<field name="setup_fee" type="tdouble"/>
<field name="transaction_fee" type="string"/>
Unfortunately you do not post all of your pojo and all of your schema, so I can only guess.
The only thing I see, from the code you posted is that you are trying to let solr do some sort of conversion for you.
That is for
#Field
private String last_indexed;
And
<date name="last_indexed">*</date>
Solr will not convert a Date to a String for you, just will not. But without a full schema and the full code of your Bean, I cannot give you a full answer.
Other things I noted from the code you post
why are you putting * within the elements of your schema as far as I know that does not have any effect
why are you extending SolrInputDocument? You do not need to. #Field is designed so that you do not need to subclass anything, but may use your model's POJOs right away.
My error was: BindingException: Could not instantiate object
I added a no variable constructor to the POJO and it started to work.
public class MyItem {
String id;
#Field("id")
public void setId(String id) {
this.id = id;
}
public String getId() {
return id;
}
public MyItem() {
}
}
To get to here the only fields in my schema were:
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="_root_" type="string" indexed="true" stored="false"/>
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="text" type="string" indexed="true" stored="false" multiValued="true"/>
<uniqueKey>id</uniqueKey>
This is the code to dump the ids in the solr.
private void dumpSolr2() throws SolrServerException {
System.out.println("dumpSolr2");
SolrQuery query = new SolrQuery();
query.setQuery( "*:*" ); // get all
query.setFields("id"); // get the id field
query.setStart(0); // row to start on. First row is 0.
query.setRows(10); // number of rows to get at a time.
System.out.println(query.toString());
QueryResponse rsp = _solr.query( query );
List<BulkLoad1Data> bulkLoad1DataList = rsp.getBeans(BulkLoad1Data.class);
RplHelper1.rplSay("bulkLoad1DataList.size(): " + bulkLoad1DataList.size());
int count = 0;
Iterator<BulkLoad1Data> i = bulkLoad1DataList.iterator();
while (i.hasNext()) {
BulkLoad1Data bld = (BulkLoad1Data) i.next();
RplHelper1.rplSay("dumpSolr2 - count: " + ++count + " " +
" id: " + bld.getId());
}
}
Iam using SOLR as my search query database.
I am facing difficulty in binding multiple nodes (a collection) within a node in SOLR. Can any body tell me the schema for the same.
My Document is as follows
namespace SOLRApp
{
public class Table1Document
{
public Table1Document()
{
MobileNos = new List<int>();
EducationalDetails = new List<EducationalDetails>();
}
[SolrField("FirstName")]
public string FirstName { get; set; }
[SolrField("MobileNos")]
public List<int> MobileNos { get; set; }
[SolrField("EducationalDetails")]
public List<EducationalDetails> EducationalDetails { get; set; }
}
public class EducationalDetails
{
public EducationalDetails()
{
Details = new List<Details>();
}
public List<Details> Details { get; set; }
}
public class Details
{
[SolrField("IntitutionName")]
public string IntitutionName { get; set; }
[SolrField("EnrollDate")]
public DateTime EnrollDate { get; set; }
[SolrField("PassoutDate")]
public DateTime PassoutDate { get; set; }
[SolrField("InstituteRating")]
public int InstituteRating { get; set; }
}
}
And my schema file is as shown below.
<field name="FirstName" type="string" indexed="true" stored="true"/>
<field name="MobileNos" type="string" indexed="true" stored="true" multiValued="true" />
<field name="EducationalDetails" type="EducationalDetails" indexed="true" stored="true" multiValued="true">
<field name="Details" type="string" indexed="true" stored="true" multiValued="true">
<field name="IntitutionName" type="string" indexed="true" stored="true"/>
<field name="EnrollDate" type="date" indexed="true" stored="true"/>
<field name="PassoutDate" type="date" indexed="true" stored="true"/>
<field name="InstituteRating" type="string" indexed="true" stored="true"/>
</field>
</field>
My main question is what would be the type of 'EducationalDetails' node. This gives me error of
Cannot initialize type 'SOLR.EducationalDetails' with a collection initializer because it does not implement 'System.Collections.IEnumerable'.
I would like to know how can we add user defined datatypes in SOLR. Like in my example, 'EducationalDetails' is a user defined datatype (class). Can any one tell me how to add that in SOLR.
Thank you in advance.

the issue here is when I do the selectComponentSpecByID query, the dynamic item list is supposed has nothing , but actual result is two elements, I think it's a problem with result map definition, but no glue. any suggestions? thanks .
finally I found the solution by myself, because when id property is null ,meaning no records retrieved in the result, mybatis still compare them and treat them as valid result and put them into sub list,that's the reason, to fix it,just define notNullColumn of Collection element preventing null id. Done!
