I'm using the latest 1.7.1 release of Elastic with Oracle JDK 8.0\_40 on Linux. The following sequence of statements don't produce what I'm expecting. What am I doing wrong? Please help, thanks. # The index curl -XPUT [http://localhost:9200/mlt\_test/\_mappings/mlt\_type](http://localhost:9200/mlt_test/_mappings/mlt_type) -d ‘{"mlt\_type":{"properties":{"text":{"type":"string","analyzer":"keyword","term\_vector":"yes"}}}}' # Added two documents curl -XPUT [http://localhost:9200/mlt\_test/mlt\_type/1](http://localhost:9200/mlt_test/mlt_type/1) -d '{"text":["1113064548","1229341624","1322900872","2721480379","3160379314","3855009424","4137621045","4241342909"]}' curl -XPUT [http://localhost:9200/mlt\_test/mlt\_type/2](http://localhost:9200/mlt_test/mlt_type/2) -d '{"text":["2566818807","2721480379","3502753730","4021564766"]}' # MLT returns doc 2 even though only 1 term matches. curl -XGET '[http://localhost:9200/mlt\_test/mlt\_type/\_search?pretty](http://localhost:9200/mlt_test/mlt_type/_search?pretty)' -d '{"fields":["id", "text"],"query":{"more\_like\_this":{"ids":["1"],"min\_term\_freq":0, "min\_doc\_freq":0, "minimum\_should\_match":"30%"}}}' I expected no results. Variations on the min/max input parameters didn't help either. ---

Thanks for the github link. Guess, I have to generate my own boolean query using the term vectors in order to gain more control over how the parameters are used. ---
