Methods
__construct
Constructs a new ezcSearchQuerySolr object for the handler $handler
The handler implements mapping field names and values based on the document $definition.
Parameters
between
string between(
string
$field, mixed
$value1,
$value2, mixed
$value2
)
Returns a string containing a field/value specifier, and an optional boost value.
The method uses the document definition field type to map the fieldname to a solr fieldname, and the $fieldType argument to escape the values correctly.
Parameters
| Name |
Type |
Description |
$field |
string |
|
$value1 |
mixed |

string
$clause, float
$boostFactor )
Modifies a clause to give it higher weight while searching.
This method accepts a clause and adds a boost factor.
Parameters

eq
string eq(
string
$field,
$value, mixed
$value
)
Returns a string containing a field/value specifier, and an optional boost value.
The method uses the document definition field type to map the fieldname to a solr fieldname, and the $fieldType argument to escape the $value correctly. If a definition is set, the $fieldType will be overridden with the type from the definition.
