We also implemented an autocomplete mechanism using ElasticSearch, indexed files, and geographical information. However, by the end of this chapter, you will have learned the following:
Why your document was matched
How to influence document score
How to use synonyms
How to handle multilingual data
How to use term position aware queries (span queries)
