What is Querqy?

Querqy is a query rewriting library. It can help you better connect user intent to the relevance signals in your search index. You can massage user input into a better query by fixing typos, removing spurious terms, or injecting filters or synonyms automatically.

Rationale

• You want to define and maintain rules client side.
• Build a rich vocabulary of rules, beyond what Querqy templates support.
• No ability, or desire, to install custom Elasticsearch plugins.
