Hi, I am trying to implement middle word search, as Completion Suggester doc[http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-suggesters-completion.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-suggesters-completion.html) said, preserve\_position\_increments: if disabled and using stopword analyzer, you could get a string starting with 'the beatles', if you suggest for 'b'. i am trying to implement same by providing below mapping: curl -XPUT '[http://localhost:9200/sugg\_test/test/\_mapping](http://localhost:9200/sugg_test/test/_mapping)' -d '{ "test" : { "properties" : { "name" : { "type" : "string" }, "auto\_suggest" : { "type" : "completion", "index\_analyzer" : "simple", "search\_analyzer" : "stop", "preserve\_position\_increments" : false, "payloads" : true } } } }' but it dosen't work. Please any body help me, where i am doing wrong. i know i can do the same by splitting the word and add them in input, but i want to implement it by mapping.

you're using the "simple" analyzer at index time, which means that it is indexing ["the","beatles"]. If you change it to use the "stop" analyzer at both search and index time then it should work. clint On 4 March 2014 15:38, Shams Haque [shams.hq@gmail.com](mailto:shams.hq@gmail.com) wrote: > Hi, > > I am trying to implement middle word search, as Completion Suggester doc[http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-suggesters-completion.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-suggesters-completion.html) said, > preserve\_position\_increments: if disabled and using stopword analyzer, you > could get a string starting with 'the beatles', if you suggest for 'b'. > > i am trying to implement same by providing below mapping: > > curl -XPUT '[http://localhost:9200/sugg\_test/test/\_mapping](http://localhost:9200/sugg_test/test/_mapping)' -d '{ "test" : > { "properties" : { "name" : { "type" : "string" }, "auto\_suggest" : { > "type" : "completion", "index\_analyzer" : "simple", "search\_analyzer" : > "stop", "preserve\_position\_increments" : false, "payloads" : true } } } }' > > but it dosen't work.
