我目前正在将一个大项目转移到 Laravel 框架 http://hobbyathletes.com/events/south-america/all-event-types/all/.我需要迁移我的内部搜索引擎，它使用以下查询(如果搜索一个词，这里有额外的预选选项南美洲):

I'm currently transfering a big project to Laravel framework http://hobbyathletes.com/events/south-america/all-event-types/all/. I need to migrate my internal searchengine, which uses the following query (if searched for one word, here additional pre-selected option South America ):

SELECT *, (
 (CASE WHEN name LIKE '%searchthis%' THEN 1000 ELSE 0 END) + 
 (CASE WHEN name LIKE 'searchthis %' THEN 10 ELSE 0 END) + 
 (CASE WHEN name LIKE 'searchthis%' THEN 1 ELSE 0 END) + 
 (CASE WHEN name LIKE '% searchthis %' THEN 5 ELSE 0 END) + 
 (CASE WHEN city LIKE '%searchthis%' THEN 500 ELSE 0 END) + 
 (CASE WHEN city LIKE 'searchthis%' THEN 10 ELSE 0 END) + 
 (CASE WHEN city LIKE 'searchthis %' THEN 1 ELSE 0 END) + 
 (CASE WHEN city LIKE '% searchthis %' THEN 5 ELSE 0 END) + 
 (CASE WHEN country LIKE '%searchthis%' THEN 500 ELSE 0 END) + 
 (CASE WHEN country LIKE 'searchthis%' THEN 10 ELSE 0 END) + 
 (CASE WHEN country LIKE 'searchthis %' THEN 1 ELSE 0 END) + 
 (CASE WHEN country LIKE '% searchthis %' THEN 5 ELSE 0 END) + 
 (CASE WHEN homepage LIKE '%searchthis%' THEN 600 ELSE 0 END) + 
 (CASE WHEN headline LIKE '%searchthis%' THEN 100 ELSE 0 END) + 
 (CASE WHEN headline LIKE 'searchthis%' THEN 10 ELSE 0 END) + 
 (CASE WHEN headline LIKE 'searchthis %' THEN 1 ELSE 0 END) + 
 (CASE WHEN headline LIKE '% searchthis %' THEN 5 ELSE 0 END) + 
 (CASE WHEN description LIKE '%searchthis%' THEN 100 ELSE 0 END) + 
 (CASE WHEN description LIKE 'searchthis%' THEN 10 ELSE 0 END) + 
 (CASE WHEN description LIKE 'searchthis %' THEN 1 ELSE 0 END) + 
 (CASE WHEN description LIKE '% searchthis %' THEN 5 ELSE 0 END) + 
 (CASE WHEN distances LIKE '%searchthis%' THEN 100 ELSE 0 END) + 
 (CASE WHEN distances LIKE 'searchthis%' THEN 10 ELSE 0 END) + 
 (CASE WHEN distances LIKE 'searchthis %' THEN 1 ELSE 0 END) + 
 (CASE WHEN distances LIKE '% searchthis %' THEN 5 ELSE 0 END) + 
 (CASE WHEN date LIKE '%2014%' THEN 300 ELSE 0 END) + 
 (CASE WHEN name LIKE '%2014%' THEN 200 ELSE 0 END) + 
 (CASE WHEN date LIKE '%2013%' THEN 200 ELSE 0 END) + 
 (CASE WHEN name LIKE '%2013%' THEN 100 ELSE 0 END) 
) 
 AS relevance 
 FROM events 
 WHERE 
 (
 country = 'Argentina' or 
 country = 'Bolivia' or 
 country = 'Brazil' or 
 country = 'Chile' or 
 country = 'Colombia' or 
 country = 'Ecuador' or 
 country = 'Guyana' or 
 country = 'Paraguay' or 
 country = 'Peru' or 
 country = 'Suriname' or 
 country = 'Uganda' or 
 country = 'Uruguay' or 
 country = 'Venezuela'
 ) 
 AND
 ( 
 name LIKE '%searchthis%' OR 
 country LIKE '%searchthis%' OR 
 city LIKE '%searchthis%' OR 
 homepage LIKE '%searchthis%' OR 
 headline LIKE '%searchthis%' OR 
 description LIKE '%searchthis%' OR 
 distances LIKE '%searchthis%'
) 
ORDER BY relevance DESC

如何将此查询转移到 Eloquent Query builder?我已经尝试过 DB:raw($query) 这似乎不起作用......尝试使用的是非常需要的 ->paginate(25) 和 ->get()，都不起作用.这里的任何人都可以让我朝着正确的方向前进吗?

How can I transfer this query to Eloquent Query builder? I tried already DB:raw($query) which seems not to work... Tried is with the much needed ->paginate(25) and with ->get(), all not working. Anyone here can put me in the right direction?
