A Filter is all about implementing some conditions in the query to reduce the matching result set. When we use a query in Elasticsearch, the query computes a relevance score for matching the documents. But in some situations, we don’t need relevance scores when the document falls in the range of two provided timestamps.
So, for this yes/no criteria, we use Filters. We use Filters for matching particular criteria, and they are cacheable to allow faster execution. The Token filters receive a flow of tokens from a tokenizer, and they can change, add, and delete the tokens.
