Custom Scoring in Elasticsearch Using function_score

Elasticsearch calculates a relevance score for each document, but using the function_score query you can customize this scoring by combining the original query_score with a user-defined func_score through various functions such as weight, random_score, field_value_factor, decay_function, and script_score, allowing flexible ranking based on business needs.
