- Setup Solarium in codeigniter
- Simple Select Query
- Simple Search Query
- Simple Facet Query
- Multiple Selection using Facet
- Set Page limit
- Select query with Between option
- Show Selective Fields
Please refer Solr-Multiconnection-Codeigniter to setup solarium in codeigniter from scratch.
This query is used to list all values from the solr core.
// Create select query
$query = $this->client->createSelect();
// Store result
$result = $this->client->select($query);
The createSelect() is to create a basic query structure in solarium. The basic query structure is as follows,
Solarium\QueryType\Select\Query\Query Object
(
[options:protected] => Array
(
[handler] => select
[resultclass] => Solarium\QueryType\Select\Result\Result
[documentclass] => Solarium\QueryType\Select\Result\Document
[query] => *:*
[start] => 0
[rows] => 10
[fields] => *,score
[omitheader] => 1
)
[tags:protected] => Array
(
)
[fields:protected] => Array
(
[*] => 1
[score] => 1
)
[sorts:protected] => Array
(
)
[filterQueries:protected] => Array
(

[helper:protected] =>
[params:protected] => Array
(
)
[components:protected] => Array
(
)
[componentTypes:protected] => Array
(
[morelikethis] => Solarium\Component\MoreLikeThis
[spellcheck] => Solarium\Component\Spellcheck
[suggest] => Solarium\Component\Suggester
[debug] => Solarium\Component\Debug
[spatial] => Solarium\Component\Spatial
[facetset] => Solarium\Component\FacetSet
[dismax] => Solarium\Component\DisMax
[edismax] => Solarium\Component\EdisMax
[highlighting] => Solarium\Component\Highlighting\Highlighting
[grouping] => Solarium\Component\Grouping
[distributedsearch] => Solarium\Component\DistributedSearch
[stats] => Solarium\Component\Stats\Stats
[queryelevation] => Solarium\Component\QueryElevation
[rerankquery] => Solarium\Component\ReRankQuery
)
)
And the select() is to process the query and store the result values.

The setQuery() is used to perform search function.
The solarium Query format is below,
$query->setQuery('field_name:"search_key"');
field_name is refer to what type of thing we found. For example price, id or some other.
search_key is refer what thing we find that field.
The solarium search is first to verify the field is available or not. If the field is available it move to find the matches. If the field is not available it's throw error message.

The getFacetSet() is used to multi-purpose function in solarium. It is used to both search and filter functionality.
The solarium Query format is below,
// Initialise facet
$facetSet = $query->getFacetSet();
// Get Facet values depends on field
$facetSet->createFacetField('field_name_shortly')->setField('field_name');
field_name is a field name.
field_name_shortly is a Facet name. It is help to retrieve the facet result using this name.
$facet = $result->getFacetSet()->getFacet('field_name_shortly');
It is return output as unique value with total count.
For example, If you have this below recards in your core.
-----------------------------
| price: 2.5 |
| id: "id1" |
-----------------------------
| price: 2.5 |
| id: "id2" |
-----------------------------
| price: 5.0 |
| id: "id3" |
-----------------------------
| price: 2.5 |
| id: "id4" |
-----------------------------
If the output of the above table depends on price field is below,
------------------------
| price | Count |
------------------------
| 2.5 | 3 |
------------------------
| 5.0 | 1 |
------------------------

In facet we use createFilterQuery() to implement multiple search.
The code structure is here,
// Multiple select using Facet
$query->createFilterQuery('price')->addTag('price')->setQuery('price:"2.5" OR price:"1.5"');
// get the facetset component
$facetSet = $query->getFacetSet();
$facetField = $facetSet->createFacetField('multiple_select');
The createFilterQuery() is used to filter the whole table/core depends on the condition like price:"2.5" OR price:"1.5".
And the createFacetField() is store the facet values with count including the createFilterQuery.

In solarium search only show 10 records for every search. Because this is the default mode for the solr.
So if you want more than 10 records in your result use setRows() in solarium.
The code structure is here,
$query->setStart('start')->setRows('no-of-rows');
The setStart() is the starting position of the result. It set '0' as default. If you set value as '5'. The result record is listed from 5th row.
The setRows() is used to how many records we want. It set '10' as default. If you set value as '50'. It shows 50 records from setStart() row.

The between is used to get value depends on some range.
For example, we need products details based on some range using this option.
This code format is below,
$query->setQuery('price:[ 0.50 TO 3 ]');
In the above line [ 0.50 TO 2 ] is refer to list the record only the price range between 0.50 to 3.
If you want the code, Please download from here.
The solarium is list all field values as default.
If you want some specific fields only to listing the output use setFields().
The code structure is below,
$query->setFields(array('id','price'));
The array is used to mention what are the fields we want.
