Users might search 8 or eight for title, I want these two word could be synonym of each other in the search result. Similar problem exist when Japanese user search for 8. They might type 8 or 八つ.
I tried to enable synonym_filter in config/elasticsearch.yml
Then create a synonym.txt with content: 8, eight
By search though commond line "POST http://localhost:9200/moegirl_content/_search", I got both 8 and eight in return result. However, on website the MW search suggestion and the MW search result doesn't match both.
Hope Wikipedia can add these synonym in search result and search suggestion too. Some article have very similar variants in title. Users have to type exactly the word to find that article. Add some necessary synonym can benefit may people.
