Lucilla's FTS index stores a map of documents and frequencies for each term, which can also be used to calculate the document frequency.

Modify the index to also store the starting position/offset for each term in the documents.

Some of my data classes are huge and adding @ignore to every field I didn't want to search would be tedious, as there are only a few fields I'd like to search with, maybe an @include would be good?

Allow users to search the index for specific properties of a document only.

For example, the ability to search only the titles of indexed books, even if other properties are indexed too:

data class Book(
  @Id val id: Int,
  val title: String,
  val description: String,
)

val index = useFts(getBooks())

// Only return results that contain "recursion" in the book title
val results = index.search("recursion", Book::title)

Lucilla treats every document as a blob of text, which does not work well for field-specific or field boosts. Storing field related information in the document would make it easier to implement such functionality.

Add ability to fetch auto completion suggestions for a search query.

A simple autocomplete suggestions provider can be built using prefix search. For a search query, return matching words in the index that contain the query as a prefix.
