How to get all results from solr query?

Question

I executed some query like \"Address:Jack*\". It show numFound = 5214 and display 100 documents in results page(I changed default display results f

Answer 1

What you should do is to first create a SolrQuery shown below and set the number of documents you want to fetch in a batch.

int lastResult=0; //this is for processing the future batch

String query = "id:[ lastResult TO *]"; // just considering id for the sake of simplicity

SolrQuery solrQuery = new SolrQuery(query).setRows(500); //setRows will set the required batch, you can change this to whatever size you want.

SolrDocumentList results = solrClient.query(solrQuery).getResults(); //execute this statement

Here I am considering an example of search by id, you can replace it with any of your parameter to search upon.

The "lastResult" is the variable you can change after execution of the first 500 records(500 is the batch size) and set it to the last id got from the results.

This will help you execute the next batch starting with last result from previous batch.

Hope this helps. Shoot up a comment below if you need any clarification.
