Question

i use solr php client.

but when i use the search method:

$params = array('qf' => 'threads.title posts.body', 'defType' => dismax);

$results = $solr->search($query, $offset, $limit, $params);

when i use defType = dismax it searches $query = ‘Peter Jakob’ as the whole string instead of Peter OR Jakob. it works fine when i dont use the $params. But main problem is i have to use dismax to be able to search in multiple fields.

How can i make solr php client to know that i have to search in multiple fields and for multiple values (OR)?

Here is my search handler im using:

<requestHandler name="standard" class="solr.SearchHandler" default="true">
    <!-- default values for query parameters -->
     <lst name="defaults">
       <str name="echoParams">explicit</str>
       <!--
       <int name="rows">10</int>
       <str name="fl">*</str>
       <str name="version">2.1</str>
        -->
     </lst>
  </requestHandler>

Solr has the interface that let’s you see how it processes your query. Maybe you can get some hints there? It’s in ANALYSIS link (http://ora.ouls.ox.ac.uk:8080/solr/admin/analysis.jsp?highlight=on ) in solr admin page (http://ora.ouls.ox.ac.uk:8080/solr/admin/ ) although it doesn’t seem to work in this instance of solr. Please check it out in your own instance.

Maybe you should read this: http://wiki.apache.org/solr/SolrQuerySyntax
and this: http://lucene.apache.org/java/2_4_0/queryparsersyntax.html

In documentation of schema.xml http://wiki.apache.org/solr/SchemaXml it is stated that

The default operator used by Solr’s
query parser (SolrQueryParser) can be
configured with

<solrQueryParser defaultOperator="AND|OR"/>

The
default operator is “OR” if
unspecified.

So it should work for you without doing anything specific.

If you want to convert $query = “Peter Jakob” to Peter OR Jakob just do the following:

$query = preg_replace('`(\\s)(\\w|"[^"]+")`', '\\1OR \\2', $query);
