i want to incorporate an additional textbox that allows users to choose words they want to have ignored in the results (like on google advanced search - none of these words) is there a search filter / query option to handle this? i would need to plug it in to the existing default search ---

Depends on how you are doing the initial query, but you can do NOT/- using simple query - [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html) ---

ok im utilising NEST within a C# project to do my search so where i have - a.Match(m =\> m.OnField("\_all").Query(m\_strSearchQuery)) - to do my existing search.... how would i access the simple search query and flag option to add to this with my "none of these words" search string? ---
