Hi everyone, I'm replacing the search on [http://jobs.perl.org/](http://jobs.perl.org/) with Elastic Search. So far everything is working very nicely - it's been a pleasure to work with (well, except the obscure errors while I was learning the query syntax). I loaded all the old/expired jobs into the index, too -- the intention was to be able to do a "more like this" query to help the user find an active similar job when requesting details for a job that's expired or been removed from the site by the poster. To do this I added an 'active: [0 | 1]' flag to each document and in regular search I just filter on this; it works great. However -- I can't figure out how to do the filter on the mlt query. Is it not possible? - ask ---

Hi Ask > However -- I can't figure out how to do the filter on the mlt query. > Is it not possible? You are using the /\_mlt query? This just gets converted to a standard search with a more\_like\_this query: [http://www.elasticsearch.com/docs/elasticsearch/rest\_api/more\_like\_this/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/more_like_this/) which you can then wrap in query filter: [http://www.elasticsearch.com/docs/elasticsearch/rest\_api/query\_dsl/query\_filter/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/query_dsl/query_filter/) clint ---

I think that it should be wrapped with a filtered query: [http://www.elasticsearch.com/docs/elasticsearch/rest\_api/query\_dsl/filtered\_query/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/query_dsl/filtered_query/), the mlt\_query will be the query, and the filter will include the active ones.

Thanks Shay & Clint: Yes - I was trying to use the 'mlt' query (with the id of the old posting). Clint pointed out to me on IRC that I need to do it with a regular search to combine it with other filters. I changed the code to just build the "like\_text" and pass it in as a regular filter and all is well now. Thanks! > - ask -- [http://askask.com/](http://askask.com/) ---
