Executes a TripalFieldQuery using the provided conditions.

This hook is called to find the entities having certain field conditions and sort them in the given field order.

Parameters

$conditions: An array of filter representing the conditions to be applied to the query. Each filter is an associative array whose keys include the following:

• field: an array representing the field identical to the output of the field_info_field() function.
• filter: the name of the field on which the filter should be applied.
• value: the value of the filter.
• operator: the operation to apply: '=', '<>', '>', '>=', '<', '<=', 'STARTS_WITH', 'CONTAINS': These operators expect $value to be a literal of the same type as the column. 'IN', 'NOT IN': These operators expect $value to be an array of literals of the same type as the column.

$orderBy: An array of sorting instructions. Each sort is an associative array with the following keys:

• field: an array representing the field identical to the output of the field_info_field() function.
• orderBy: the name of the field on which the filter should be applied.
• direction: either the string 'ASC' (for ascending sort) or 'DESC' (for descending).
