Thanks everyone, that was a very informative thread. One more curiosity: why are different set of fields being used based on the query string:-
http://localhost:8983/solr/filesearch/select?fq=id:1193&; q=*:*&debugQuery=true - parsedquery: "+DisjunctionMaxQuery((user_email:*:* | user_name:*:* | tags:*:* | (name_shingle_zh-cn:, , name_shingle_zh-cn:, ,) | id:*:*)~0.01) DisjunctionMaxQuery(((name_shingle_zh-cn:", , , ,"~100)^100.0 | tags:*:*)~0.01)", I find it perplexing as the default values for qf and pf are very different from above so I am not sure where these fields are coming from (although they are all valid fields) e.g. following query uses the my expected set of pf and qf. http://localhost:8983/solr/filesearch/select?fq=id:1193&; q=hello&debugQuery=true - parsedquery: "+DisjunctionMaxQuery(((name_token:hello)^60.0 | user_email:hello | (name_combined:hello)^10.0 | (name_zh-cn:hello)^10.0 | name_shingle:hello | comments:hello | user_name:hello | description:hello | file_content_zh-cn:hello | file_content_de:hello | tags:hello | file_content_it:hell | file_content_fr:hello | file_content_es:hell | file_content_en:hello | id:hello)~0.01) DisjunctionMaxQuery((description:hello | (name_shingle:hello)^100.0 | comments:hello | tags:hello)~0.01)", On Sat, Jan 6, 2018 at 12:05 PM, Chris Hostetter <hossman_luc...@fucit.org> wrote: > > : Yes, i am using dismax.
