what is solr's default query parser

Question

i am confused by these words in the solr document:

https://cwiki.apache.org/confluence/display/solr/The+Standard+Query+Parser

Before Solr 1.3, the Standard Request Handler called the standard query parser as the default query parser. In versions since Solr 1.3, the Standard Request Handler calls the DisMax query parser as the default query parser.

https://cwiki.apache.org/confluence/display/solr/The+DisMax+Query+Parser

The q parameter does not support wildcard characters such as *.

so i download solr 4.7.2, unzip it

checking that i have

  <requestHandler name="/select" class="solr.SearchHandler">

in solr-4.7.2/example/solr/collection1/conf/solrconfig.xml, by default.

then, i index this document

<?xml version="1.0"?>
<add>
  <doc boost="1.0">
        <field name="id">item1</field>
    </doc>
</add>

but

http://localhost:8983/solr/collection1/select?q=id:it*

finds the document,

http://localhost:8983/solr/collection1/select?q=id:it*defType=dismax

finds no item

so looks like standard query parser is the default instead of the dismax query parser?

Answer 1

The default is defined in your solrconfig.xml file. The default solrconfig.xml file that comes with 4.7.2 has the following entry:

edismax

This means that the default is the extended dismax query parser. http://wiki.apache.org/solr/ExtendedDisMax
