Hi @Kishore Nallan, @Jason Bosco Can I filter search result for string using following scenario: 1. Contains with "" 2. Start with ""

For contains check on the infix query option. However you need to enable that index during collection creation and it can be quite performance intensive. Starts with is supported by prefix search which is enabled by default.

This is my document and below is search query:

{
  "q": "su",
  "query_by": "name",
  "filter_by": "opening_name:ta"
}

You can only do exact searching on filters
