Hello, I'm using MoreLikeThisRequestBuilder to prepare a query.  
Everything works fine, but I need to filter the result. For example I  
need to return all MLT documents but they must have certain value in  
some field. In Solr I had filter query, do we have something like this  
in ElasticSearch?  
Thank you,  
Eugene S.

You have two options: Either pass to setSearchSource a SearchSourceBuilder  
initialized with a filter, or, build your own mlt by creating your own  
search request that includes an mlt query (wrapped in other queries,  
with/without filters), with the text for the mlt extracted from the  
relevant doc you want.

Thank you, I've used the first option and it looks fine. Here is an  
example for someone who would have such task in future:

SearchResponse  
response=clientProvider.getClient().prepareMoreLikeThis(  
clientProvider.getIndexName(), "post", postId)  
.setField("text")  
.setSearchSource(  
SearchSourceBuilder.searchSource()  
.query(QueryBuilders.matchAllQuery())  
.filter(FilterBuilders.andFilter(  
FilterBuilders.termFilter("imgWidth", 300),  
FilterBuilders.termFilter("replica", false)))  
)  
.setMinTermFreq(1)  
.setSearchFrom(0)  
.setSearchSize(settings.getPostsOnPage())  
.execute().actionGet();
