在SOLR中完全导入NEW索引后保留OLD索引。

Question

I am using SOLR 3.5.0..!!

I have made two Indexes : " Cars " and " Vendors "

Both indexes fetch results from the Database and populate Documents..!!

My request handlers are as follows :

    <requestHandler name="/selectCars" class="org.apache.solr.handler.dataimport.DataImportHandler">
      <lst name="defaults">
        <str name="config">solr/jcoreDocuments/CarsConfig.xml</str>
      </lst>
    </requestHandler>

     <requestHandler name="/selectVendors" class="org.apache.solr.handler.dataimport.DataImportHandler">
        <lst name="defaults">
        <str name="config">solr/jcoreDocuments/vendorConfig.xml</str>
        </lst>
     </requestHandler>

Now when i hit the following URL :

http://localhost:8983/solr/selectVendors?command=full-import

It fetches the corresponding 47531 documents..!!

when i hit : http://localhost:8983/solr/select?q=*:* .... It shows that i have 47531 documents available..!! (THATS CORRECT)

Now when i want to fetch my " Cars " documents, but retaining the " Vendor " documents..I hit the following URL :

http://localhost:8983/solr/selectCars?command=full-import&clean=false

It shows that it has fetched corresponding 802 documents..!!

Now when i hit http://localhost:8983/solr/select?q=*:* ....I still have 47531 documents available ..!!

(But now it contains 802 NEW - Cars documents and REDUCED 46729 Vendors documents )

---

Note : After fetching two Indexes the total documents should be 47531 + 802 = 48333

How is it possible...Am i missing something..??

When you are reindexing data with the same ID would be "updated" that might mean your vendors would become cars. In your dataimport conf change id to they will be unique for vendors and cars
