Exercises: wildcard and regex

wildcard

🔗 Playground link: words that starts-with not matching as expected

Solution

"analyzer": "lucene.standard"

The matching needs to occur at the word level, and thus needs (non-keyword) tokenization.

And allowAnalyzedField: true needs to be set, allowing searches when using a tokenizing analyzer.

regex

🔗 Playground link: Full string regex not working as expected

Solution

"analyzer": "lucene.keyword"

Matching needs to occur across the full string, and thus needs to be lucene.keyword analyzed so that the full string is indexed as a single unit.
