The forgotten daughter of Elip, inheriting it's minimalism.

Elipdotter is an embeddable, rusty full-text search engine, with fuzzy search and rating of results. It supports complex queries using AND, OR, and NOT operators with parentheses.

Kvarn integration

Using the kvarn-search, you can easily use this search engine in your Kvarn web server.

Usage example

See the source of kvarn-search for a comprehensive example.

The tests of this crate contain minimal examples.



  • Removed unwanted debugging.


  • Added lossless index for faster query resolution times.
    • 10x better performance at the cost of having all the documents in memory.
  • Fixed parsing issue where for me would be parsed as OR(f, me).
  • Fixed issue with AND NOT, where AND didn't find the closest NOT occurrence.
  • Added size method to indices to estimate the memory usage.
  • Improvements to docs.


  • Fixed issue where AND NOT queries got erroneous results.
  • Fixed issue with OR queries. Now all occurrences in either of the documents are returned.
  • Major improvements to relevancy of results, by checking more combinations of occurrences within a document. Small performance impact.
  • Text next-gen is now matched by the query nextgen - words with hyphens are registered as both separate words and one single.
  • Better docs.
  • Fewer allocations - less memory usage.
