Hi,

I am trying to filter moreLikeThis results by adding additional query - but  
it seems to ignore it at all.

I tried to run my ignoreQuery separately and it works fine, but how to make  
it work with moreLikeThis? Please help me.

$ignoreQuery = $this-\>IgnoreCategoryQuery('movies')

$this-\>resultsSet = $this-\>index-\>moreLikeThis(  
new \Elastica\Document($id),  
array\_merge($this-\>mlt\_fields, array('search\_size' =\> $this-\>size  
, 'search\_from' =\> $this-\>from)),  
$ignoreQuery);

My IgnoreCategory function:

public function IgnoreCategoryQuery($category = 'main')  
{  
$categoriesTermQuery = new \Elastica\Query\Term();  
$categoriesTermQuery-\>setTerm('categories', $category);

$categoriesBoolQuery = new \Elastica\Query\Bool();  
$categoriesBoolQuery-\>addMustNot($categoriesTermQuery);

return $categoriesBoolQuery;  
}

Hello Alexey,

You should use the query DSL and not the more like this API. You can create  
a boolean query where one clause is your more like this query and the other  
one is your ignore category query (better use a filter here if you can).

However, more like this of the DSL only takes a like\_text parameter, you  
cannot pass the id of the document. This will change in a subsequent  
version of ES. For now, to simulate this functionality, you can use  
multiple mlt queries with a like\_text set to the value of each field of the  
queried document, inside a boolean query. Let me know if this helps.

Alex
