Hello, in my index, there are certain documents that I want to disable or hide during a k-nearest neighbors (KNN) search. However, there may be situations where I need to enable or reveal these documents. How can I do this? ---

Hello @r1ckC139, When talking about disabling some documents, are you referring to restricting the search? If so, you can consider performing a [filtered kNN](https://www.elastic.co/guide/en/elasticsearch/reference/current/knn-search.html#knn-search-filter-example) search. The search will return the top k documents that also match the filter query. In situations that you don’t need it you would simply not perform a filtered search. ---

However, there may be situations where I need to enable or reveal these documents. How can I do this? Hi, you can use a filtered search to ignore these documents. You can add a filter to your k-nearest neighbors (KNN) search query to only include documents where the vector-embedding field exists. Regards ---

Hi I have tried and found that, documents without embedding fields will be automatically ignored by Elasticsearch. ---
