Getting only 10 rows in Solr Cassandra search

问题

I am working on Datastax Cassandra with Apache Solr for multiple partial search. Issue is, everytime I am getting only 10 rows even once I am doing count(*) query, I am able to check there are 1300 rows belong to particular query.

nandan@cqlsh:testo> select id from empo where solr_query = 'isd:9*';

 id

 6669cc42-6f47-11e6-8b77-86f30ca893d3

(10 rows)

After searching few links, I make changes into solrconfig.xml file. and changes are as below.

<requestHandler class="solr.SearchHandler" default="true" name="search">
    <!-- default values for query parameters can be specified, these
         will be overridden by parameters in the request
      -->
     <lst name="defaults">
       <int name="rows">1000000</int>
     </lst>
 <!-- SearchHandler for CQL Solr queries:
    this handler doesn't support any additional components, only default parameters
    -->

  <requestHandler class="com.datastax.bdp.search.solr.handler.component.CqlSearchHandler" name="solr_query">
     <lst name="defaults">
       <int name="rows">1000000</int>
     </lst>
  </requestHandler>

But still I am getting same issue. Please let me know what will be the solution for this. Thanks.

回答1:

I don't think it should be managed from the schema. The query has a rows and a start parameter. Use those: rows defines the max number of items to return, start defines the first item in the list to return:

q=isd:9*&rows=22&start=17&wt=json

isd:9* returns all items where isd starts with 9.

start=17 says begin at the 18th item in the list.

rows=22 returns 22 items, from 18 to 40.

try this

select id from empo where solr_query = 'isd:9*' limit 1300;

this will give you all 1300 rows, by default solr limits the rows it return to 10.
