Fetching records in solr:

Once you have finished with indexing in solr, now you can perform search on your records with the help of queries.

Go to the url:

http://localhost:8983/solr/#/collection/query 

There is box with q, here you can query for your records. For fetching all records we write *:* and execute the queries, the records will be fetched accordingly.

Limiting the records based on the no. of word per record:

Suppose we have indexed this file example.xml

<add>
  <doc>
    
    <field name="record1">
  This is an example.This is an example.This is an example.</field>
  <field name="record2">This is an example.This is an example.This is an example.This is an example.</field>
 </doc>
  <doc>
    
    <field name="record1">
  This is an example.</field>
  <field name="record2">This is an example.</field>
 </doc>
  <doc>
    
    <field name="record1">
  This is example </field>
  <field name="record2">This is an example.This is an example.This is an example.This is an example.</field>
 </doc>
  <doc>
    
    <field name="record1">
  This is an example.This is an example</field>
  <field name="record2">Example</field>
 </doc>
  <doc>
    
    <field name="record1">
  This is an example.This is an example</field>
  <field name="record2">This is an example.This is an example.This is an example.This is an example.</field>
 </doc>
</add>

If you want to fetch the records from the field named record1 which should not be more than fifteen characters than you can write a filter query along with main query using regex:

/.{0,14}./

so the filter query will be:

 record1:/.{0,14}./

 and if you want to specify the least no. of words, suppose at least 15 should be there per record, then you can use the regex:

/.{15}./
