| This tutorial presents examples in {{esql}} syntax. Refer to [the Query DSL version](querydsl-full-text-filter-tutorial.md) for the equivalent examples in Query DSL syntax. | ||

| This is a hands-on introduction to the basics of [full-text search](full-text.md) with Elasticsearch, also known as *lexical search*, and how to filter search results based on exact criteria. In this scenario, we're implementing a search function for a cooking blog. The blog contains recipes with various attributes including textual content, categorical data, and numerical ratings. |

Here we focus primarily on lexical search. where do you think we should add a note on semantic search with match? If possible I would add a section on semantic search in this guide - can also be done as a follow up.

@ioanatia happy to do it here. The first pass was just duplicating the existing tutorial but I agree that given the simplicity of working with semantic_text in the match workflow, why not add that here too.

Do you think we should move this closer to FROM, so it doesn't interfere with score calculation but is part of the filtering part?

ESQL equivalent of existing tutorial + semantic search bonus
I had a bash at adding this to learn the new syntax, hopefully at least a few of the examples are correct 😄
