Hi,

i'm a new user but elastic search is amazing! I use it for a PHP  
project and use the elastica php client.

I created an index and insert 30.000 documents. With mysql i search  
title like 'foo bar boo' and he finds 5 entrys. If i try eleastic  
search with the more like this function i doesn't find any entry. Only  
if if i set min\_term\_freq to 1.

I thing it musst be an error on analyzing the text?

The Code:  
$queryMlt = new Elastica\_Query\_MoreLikeThis();  
$queryMlt-\>setFields(array('humanTitle'));  
$queryMlt-\>setLikeText(strtolower($filter['mltTitle']));  
$queryMlt-\>setMinTermFrequency(2);  
$queryMlt-\>setAnalyzer('whitespace');  
$queryBool-\>addMust($queryMlt);  
Doesn't find any thing.

The Mapping is like this:  
$mapping = array(  
'title' =\> array('type' =\> 'string', 'store' =\>  
'yes','index'=\>'analyzed','analyzer'=\>'simple'),  
'humanTitle' =\> array('type' =\> 'string', 'store' =\>  
'yes','index'=\>'analyzed'),  
'categoryId' =\> array('type' =\> 'integer', 'store' =\>  
'yes'),  
'showDate' =\> array('type' =\> 'string', 'store' =\>  
'no'),  
'genre' =\> array('type' =\> 'string', 'store' =\>  
'no','index'=\>'analyzed'),  
'image' =\> array('type' =\> 'string', 'store' =\>  
'yes','index'=\>'no'),  
'status' =\> array('type' =\> 'string', 'store' =\>  
'no','index'=\>'analyzed'),  
);

Where is the fault?
