Class type

A functor for building a Tfidf search index over one type of document.

Parameters

module Uid : Uid

module Doc : sig ... end

type doc = Doc.t

The type of documents we will search over

type uid = Uid.t

The type of unique identifiers we will use to identify distinct documents

type t

The search index

val index : t -> uid:uid -> token:string -> doc -> unit

index t doc uid indexes a given document doc in t with a unique identifier uid.

val add_document : t -> uid -> doc -> unit

Adds a new document to the indexer

val add_index : t -> (doc -> string) -> unit

Adds a new index and re-indexes everything.

val add_indexes : t -> (doc -> string) list -> unit

Same as add_index but allows you to add multiple indexes at a time before re-indexing occurs.

val search : t -> string -> doc list

search t k searches for t using k.

val empty : 
  ?santiser:(string -> string) ->
  ?strategy:(string -> string list) ->
  ?tokeniser:(string -> string list) ->
  unit ->
  t

Create a new empty search index.

parameter sanitiser
Run on each token to normalise them, by default this is String.lowercase_ascii

parameter strategy
The indexing strategy, by default this is a prefixing strategy such that abc is indexed with a, ab and abc

val pp : Format.formatter -> t -> unit

Dumps the index, mainly for debugging or testing.
